[\fIinterval\fR [\fIcount\fR]] .fi .SH DESCRIPTION .sp .LP The \fBzpool\fR command configures \fBZFS\fR storage pools. A storage pool is a collection of devices that provides physical storage and data replication for \fBZFS\fR datasets. .sp .LP All datasets within a storage pool share the same space. See \fBzfs\fR(1M) for information on managing datasets. .SS "Virtual Devices (vdevs)" .sp .LP A \fBvirtual device\fR describes a single device or a collection of devices organized according to certain performance and fault characteristics. The following virtual devices are supported: .sp .ne 2 .mk .na \fB\fBdisk\fR\fR .ad .sp .6 .RS 4n A block device, typically located under \fB/dev/dsk\fR. \fBZFS\fR can use individual slices or partitions, though the recommended mode of operation is to use whole disks. A disk can be specified by a full path, or it can be a shorthand name (the relative portion of the path under \fB/dev/dsk\fR). A whole disk can be specified by omitting the slice or partition designation. Alternatively, whole disks can be specified using the \fB/dev/chassis/.../disk\fR path that describes the disk's current location. When given a whole disk, \fBZFS\fR automatically labels the disk, if necessary. .RE .sp .ne 2 .mk .na \fB\fBfile\fR\fR .ad .sp .6 .RS 4n A regular file. The use of files as a backing store is strongly discouraged. It is designed primarily for experimental purposes, as the fault tolerance of a file is only as good as the file system of which it is a part. A file must be specified by a full path. .RE .sp .ne 2 .mk .na \fB\fBmirror\fR\fR .ad .sp .6 .RS 4n A mirror of two or more devices. Data is replicated in an identical fashion across all components of a mirror. A mirror with \fIN\fR disks of size \fIX\fR can hold \fIX\fR bytes and can withstand (\fIN-1\fR) devices failing before data integrity is compromised. .RE .sp .ne 2 .mk .na \fB\fBraidz\fR\fR .ad .br .na \fB\fBraidz1\fR\fR .ad .br .na \fB\fBraidz2\fR\fR .ad .br .na \fB\fBraidz3\fR\fR .ad .sp .6 .RS 4n A variation on \fBRAID-5\fR that allows for better distribution of parity and eliminates the "\fBRAID-5\fR write hole" (in which data and parity become inconsistent after a power loss). Data and parity is striped across all disks within a \fBraidz\fR group. .sp A \fBraidz\fR group can have single-, double- , or triple parity, meaning that the \fBraidz\fR group can sustain one, two, or three failures, respectively, without losing any data. The \fBraidz1\fR \fBvdev\fR type specifies a single-parity \fBraidz\fR group; the \fBraidz2\fR \fBvdev\fR type specifies a double-parity \fBraidz\fR group; and the \fBraidz3\fR \fBvdev\fR type specifies a triple-parity \fBraidz\fR group. The \fBraidz\fR \fBvdev\fR type is an alias for \fBraidz1\fR. .sp A \fBraidz\fR group with \fIN\fR disks of size \fIX\fR with \fIP\fR parity disks can hold approximately (\fIN-P\fR)*\fIX\fR bytes and can withstand \fIP\fR device(s) failing before data integrity is compromised. The minimum number of devices in a \fBraidz\fR group is one more than the number of parity disks. The recommended number is between 3 and 9 to help increase performance. .RE .sp .ne 2 .mk .na \fB\fBspare\fR\fR .ad .sp .6 .RS 4n A special pseudo-vdev which keeps track of available hot spares for a pool. For more information, see the "Hot Spares" section. .RE .sp .ne 2 .mk .na \fB\fBlog\fR\fR .ad .sp .6 .RS 4n A separate-intent log device. If more than one log device is specified, then writes are load-balanced between devices. Log devices can be mirrored. However, \fBraidz\fR \fBvdev\fR types are not supported for the intent log. For more information, see the "Intent Log" section. .RE .sp .ne 2 .mk .na \fB\fBcache\fR\fR .ad .sp .6 .RS 4n A device used to cache storage pool data. A cache device cannot be configured as a mirror or \fBraidz\fR group. For more information, see the "Cache Devices" section. .RE .sp .LP Virtual devices cannot be nested, so a mirror or \fBraidz\fR virtual device can only contain files or disks. Mirrors of mirrors (or other combinations) are not allowed. .sp .LP A pool can have any number of virtual devices at the top of the configuration (known as \fBroot vdevs\fR). Data is dynamically distributed across all top-level devices to balance data among devices. As new virtual devices are added, \fBZFS\fR automatically places data on the newly available devices. .sp .LP Virtual devices are specified one at a time on the command line, separated by whitespace. The keywords \fBmirror\fR and \fBraidz\fR are used to distinguish where a group ends and another begins. For example, the following creates two root vdevs, each a mirror of two disks: .sp .in +2 .nf # \fBzpool create mypool mirror c0t0d0 c0t1d0 mirror c1t0d0 c1t1d0\fR .fi .in -2 .sp .sp .LP Alternatively, the following command could be used: .sp .in +2 .nf # \fBzpool create tank \e mirror \e /dev/chassis/RACK29.U01-04/DISK_00/disk \e /dev/chassis/RACK29.U05-08/DISK_00/disk \e mirror \e /dev/chassis/RACK29.U01-04/DISK_01/disk \e /dev/chassis/RACK29.U05-08/DISK_01/disk\fR .fi .in -2 .sp .SS "Pool or Device Failure and Recovery" .sp .LP \fBZFS\fR supports a rich set of mechanisms for handling device failure and data corruption. All metadata and data is checksummed, and \fBZFS\fR automatically repairs bad data from a good copy when corruption is detected. .sp .LP In order to take advantage of these features, a pool must make use of some form of redundancy, using either mirrored or \fBraidz\fR groups. While \fBZFS\fR supports running in a non-redundant configuration, where each root vdev is simply a disk or file, this is strongly discouraged. A single case of bit corruption can render some or all of your data unavailable. .sp .LP A pool's health status is described by one of four states: .sp .ne 2 .mk .na \fB\fBDEGRADED\fR\fR .ad .sp .6 .RS 4n A pool with one or more failed devices, but the data is still available due to a redundant configuration. .RE .sp .ne 2 .mk .na \fB\fBONLINE\fR\fR .ad .sp .6 .RS 4n A pool that has all devices operating normally. .RE .sp .ne 2 .mk .na \fB\fBSUSPENDED\fR\fR .ad .sp .6 .RS 4n A pool that is waiting for device connectivity to be restored. A suspended pool remains in the wait state until the device issue is resolved. .RE .sp .ne 2 .mk .na \fB\fBUNAVAIL\fR\fR .ad .sp .6 .RS 4n A pool with corrupted metadata, or one or more unavailable devices and insufficient replicas to continue functioning. .RE .sp .LP The health of the top-level vdev, such as mirror or \fBraidz\fR device, is potentially impacted by the state of its associated vdevs, or component devices. A top-level vdev or component device is in one of the following states: .sp .ne 2 .mk .na \fB\fBDEGRADED\fR\fR .ad .sp .6 .RS 4n One or more top-level vdevs is in the degraded state because one or more component devices are offline. Sufficient replicas exist to continue functioning. .sp One or more component devices is in the degraded or faulted state, but sufficient replicas exist to continue functioning. The underlying conditions are as follows: .RS +4 .TP .ie t \(bu .el o The number of checksum errors exceeds acceptable levels and the device is degraded as an indication that something may be wrong. \fBZFS\fR continues to use the device as necessary. .RE .RS +4 .TP .ie t \(bu .el o The number of I/O errors exceeds acceptable levels. The device could not be marked as faulted because there are insufficient replicas to continue functioning. .RE .RE .sp .ne 2 .mk .na \fB\fBOFFLINE\fR\fR .ad .sp .6 .RS 4n The device was explicitly taken offline by the \fBzpool offline\fR command. .RE .sp .ne 2 .mk .na \fB\fBONLINE\fR\fR .ad .sp .6 .RS 4n The device is online and functioning. .RE .sp .ne 2 .mk .na \fB\fBREMOVED\fR\fR .ad .sp .6 .RS 4n The device was physically removed while the system was running. Device removal detection is hardware-dependent and may not be supported on all platforms. .RE .sp .ne 2 .mk .na \fB\fBUNAVAIL\fR\fR .ad .sp .6 .RS 4n The device could not be opened. If a pool is imported when a device was unavailable, then the device will be identified by a unique identifier instead of its path since the path was never correct in the first place. .RE .sp .LP If a device is removed and later reattached to the system, \fBZFS\fR attempts to put the device online automatically. Device attach detection is hardware-dependent and might not be supported on all platforms. .SS "Hot Spares" .sp .LP \fBZFS\fR allows devices to be associated with pools as \fBhot spares\fR. These devices are not actively used in the pool, but when an active device fails, it is automatically replaced by a hot spare. To create a pool with hot spares, specify a \fBspare\fR vdev with any number of devices. For example, .sp .in +2 .nf # \fBzpool create pool mirror c0d0 c1d0 spare c2d0 c3d0\fR .fi .in -2 .sp .sp .LP Spares can be added with the \fBzpool add\fR command and removed with the \fBzpool remove\fR command. Once a spare replacement is initiated, a new spare vdev is created within the configuration that will remain there until the original device is replaced. At this point, the hot spare becomes available again if another device fails. .sp .LP An in-progress spare replacement can be cancelled by detaching the hot spare. If the original faulted device is detached, then the hot spare assumes its place in the configuration, and is removed from the spare list of all active pools. .sp .LP If the original failed device is physically replaced, brought back online, or the errors are cleared, either through an FMA event or by using the \fBzpool online\fR or \fBzpool clear\fR commands, and the state of the original device becomes healthy, the \fBINUSE\fR spare device will become \fBAVAIL\fR again. .sp .LP Spares cannot replace log devices. .SS "Intent Log" .sp .LP The \fBZFS\fR Intent Log (\fBZIL\fR) satisfies \fBPOSIX\fR requirements for synchronous transactions. For instance, databases often require their transactions to be on stable storage devices when returning from a system call. \fBNFS\fR and other applications can also use \fBfsync\fR() to ensure data stability. By default, the intent log is allocated from blocks within the main pool. However, it might be possible to get better performance using separate intent log devices such as \fBNVRAM\fR or a dedicated disk. For example: .sp .in +2 .nf # \fBzpool create pool c0d0 c1d0 log c2d0\fR .fi .in -2 .sp .sp .LP Multiple log devices can also be specified, and they can be mirrored. See the EXAMPLES section for an example of mirroring multiple log devices. .sp .LP Log devices can be added, replaced, attached, detached, and imported, and exported as part of the larger pool. Mirrored log devices can be removed by specifying the top-level mirror for the log. .SS "Cache Devices" .sp .LP Devices can be added to a storage pool as \fBcache devices\fR. These devices provide an additional layer of caching between main memory and disk. For read-heavy workloads, where the working set size is much larger than what can be cached in main memory, using cache devices allow much more of this working set to be served from low latency media. Using cache devices provides the greatest performance improvement for random read-workloads of mostly static content. .sp .LP To create a pool with cache devices, specify a \fBcache\fR \fIvdev\fR with any number of devices. For example: .sp .in +2 .nf # \fBzpool create pool c0d0 c1d0 cache c2d0 c3d0\fR .fi .in -2 .sp .sp .LP Cache devices cannot be mirrored or part of a \fBraidz\fR configuration. If a read error is encountered on a cache device, that read \fBI/O\fR is reissued to the original storage pool device, which might be part of a mirrored or \fBraidz\fR configuration. .sp .LP The content of the cache devices is considered volatile, as is the case with other system caches. .SS "Processes" .sp .LP Each imported pool has an associated process, named \fBzpool-\fR\fIpoolname\fR. The threads in this process are the pool's I/O processing threads, which handle the compression, checksumming, and other tasks for all I/O associated with the pool. This process exists to provides visibility into the CPU utilization of the system's storage pools. The existence of this process is an unstable interface. .SS "Properties" .sp .LP Each pool has several properties associated with it. Some properties are read-only statistics while others are configurable and change the behavior of the pool. The following are read-only properties: .sp .ne 2 .mk .na \fB\fBallocated\fR\fR .ad .sp .6 .RS 4n Amount of storage space within the pool that has been physically allocated. This property can also be referred to by its shortened column name, \fBalloc\fR. .RE .sp .ne 2 .mk .na \fB\fBcapacity\fR\fR .ad .sp .6 .RS 4n Percentage of pool space used. This property can also be referred to by its shortened column name, \fBcap\fR. .RE .sp .ne 2 .mk .na \fB\fBdedupratio\fR\fR .ad .sp .6 .RS 4n The deduplication ratio specified for a pool, expressed as a multiplier. This value is expressed as a single decimal number. For example, a \fBdedupratio\fR value of \fB1.76\fR indicates that 1.76 units of data were stored but only 1 unit of disk space was actually consumed. This property can also be referred to by its shortened column name, \fBdedup\fR. .sp Deduplication can be enabled as follows: .sp .in +2 .nf # \fBzfs set dedup=on \fIpool\fR/\fIdataset\fR\fR .fi .in -2 .sp The default value is \fBoff\fR. .sp See \fBzfs\fR(1M) for a description of the deduplication feature. .RE .sp .ne 2 .mk .na \fB\fBfree\fR\fR .ad .sp .6 .RS 4n Number of blocks within the pool that are not allocated. .RE .sp .ne 2 .mk .na \fB\fBguid\fR\fR .ad .sp .6 .RS 4n A unique identifier for the pool. .RE .sp .ne 2 .mk .na \fB\fBhealth\fR\fR .ad .sp .6 .RS 4n The current health of the pool. Health can be \fBONLINE\fR, \fBDEGRADED\fR, \fBUNAVAIL\fR, or \fBSUSPENDED\fR. .RE .sp .ne 2 .mk .na \fB\fBsize\fR\fR .ad .sp .6 .RS 4n Total size of the storage pool. .RE .sp .LP These space usage properties report actual physical space available to the storage pool. The physical space can be different from the total amount of space that any contained datasets can actually use. The amount of space used in a \fBraidz\fR configuration depends on the characteristics of the data being written. In addition, \fBZFS\fR reserves some space for internal accounting that the \fBzfs\fR(1M) command takes into account, but the \fBzpool\fR command does not. For non-full pools of a reasonable size, these effects should be invisible. For small pools, or pools that are close to being completely full, these discrepancies may become more noticeable. .sp .LP The following property can be set at creation time and import time: .sp .ne 2 .mk .na \fB\fBaltroot\fR\fR .ad .sp .6 .RS 4n Alternate root directory. If set, this directory is prepended to any mount points within the pool. This can be used when examining an unknown pool where the mount points cannot be trusted, or in an alternate boot environment, where the typical paths are not valid. \fBaltroot\fR is not a persistent property. It is valid only while the system is up. Setting \fBaltroot\fR defaults to using \fBcachefile=none\fR, though this may be overridden using an explicit setting. .RE .sp .LP The following property can be set at import time: .sp .ne 2 .mk .na \fB\fBreadonly\fR=\fBon\fR | \fBoff\fR\fR .ad .sp .6 .RS 4n Controls whether the pool can be modified. When enabled, any synchronous data that exists only in the intent log is not accessible until the pool is imported in read-write mode. .sp Importing a pool in read-only mode has the following limitations: .RS +4 .TP .ie t \(bu .el o Attempts to set additional pool properties during the import are ignored. .RE .RS +4 .TP .ie t \(bu .el o All file system mounts are converted to include the read-only (\fBro\fR) mount option. .RE A pool that has been imported in read-only mode can be restored to read-write mode by exporting and importing the pool. .RE .sp .LP The following properties can be set at creation time and import time, and later changed with the \fBzpool set\fR command: .sp .ne 2 .mk .na \fB\fBautoexpand\fR=\fBon\fR | \fBoff\fR\fR .ad .sp .6 .RS 4n Controls automatic pool expansion when the underlying LUN is grown. If set to \fBon\fR, the pool will be resized according to the size of the expanded device. If the device is part of a mirror or \fBraidz\fR then all devices within that mirror/\fBraidz\fR group must be expanded before the new space is made available to the pool. The default behavior is \fBoff\fR. This property can also be referred to by its shortened column name, \fBexpand\fR. .RE .sp .ne 2 .mk .na \fB\fBautoreplace\fR=\fBon\fR | \fBoff\fR\fR .ad .sp .6 .RS 4n Controls automatic device replacement. If set to \fBoff\fR, device replacement must be initiated by the administrator by using the \fBzpool replace\fR command. If set to \fBon\fR, any new device, found in the same physical location as a device that previously belonged to the pool, is automatically formatted and replaced. The default behavior is \fBoff\fR. This property can also be referred to by its shortened column name, \fBreplace\fR. .RE .sp .ne 2 .mk .na \fB\fBbootfs\fR=\fIpool\fR/\fIdataset\fR\fR .ad .sp .6 .RS 4n Identifies the default bootable dataset for the root pool. This property is expected to be set mainly by the installation and upgrade programs. .RE .sp .ne 2 .mk .na \fB\fBcachefile\fR=\fIpath\fR | \fBnone\fR\fR .ad .sp .6 .RS 4n Controls the location of where the pool configuration is cached. Discovering all pools on system startup requires a cached copy of the configuration data that is stored on the root file system. All pools in this cache are automatically imported when the system boots. Some environments, such as install and clustering, need to cache this information in a different location so that pools are not automatically imported. Setting this property caches the pool configuration in a different location that can later be imported with \fBzpool import -c\fR. Setting it to the special value \fBnone\fR creates a temporary pool that is never cached, and the special value \fB\&''\fR (empty string) uses the default location. .sp Multiple pools can share the same cache file. Because the kernel destroys and recreates this file when pools are added and removed, care should be taken when attempting to access this file. When the last pool using a \fBcachefile\fR is exported or destroyed, the file is removed. .RE .sp .ne 2 .mk .na \fB\fBdedupditto\fR=\fInumber\fR\fR .ad .sp .6 .RS 4n Sets a threshold for number of copies. If the reference count for a deduplicated block goes above this threshold, another ditto copy of the block is stored automatically. The default value is \fB0\fR. .RE .sp .ne 2 .mk .na \fB\fBdelegation\fR=\fBon\fR | \fBoff\fR\fR .ad .sp .6 .RS 4n Controls whether a non-privileged user is granted access based on the dataset permissions defined on the dataset. The default value is \fBon\fR. See \fBzfs\fR(1M) for more information on \fBZFS\fR delegated administration. .RE .sp .ne 2 .mk .na \fB\fBfailmode\fR=\fBwait\fR | \fBcontinue\fR | \fBpanic\fR\fR .ad .sp .6 .RS 4n Controls the system behavior in the event of catastrophic pool failure. This condition is typically a result of a loss of connectivity to the underlying storage device(s) or a failure of all devices within the pool. The behavior of such an event is determined as follows: .sp .ne 2 .mk .na \fB\fBwait\fR\fR .ad .sp .6 .RS 4n Blocks all \fBI/O\fR access to the pool until the device connectivity is recovered and the errors are cleared. A pool remains in the wait state until the device issue is resolved. This is the default behavior. .RE .sp .ne 2 .mk .na \fB\fBcontinue\fR\fR .ad .sp .6 .RS 4n Returns \fBEIO\fR to any new write \fBI/O\fR requests but allows reads to any of the remaining healthy devices. Any write requests that have yet to be committed to disk would be blocked. .RE .sp .ne 2 .mk .na \fB\fBpanic\fR\fR .ad .sp .6 .RS 4n Prints out a message to the console and generates a system crash dump. .RE .RE .sp .ne 2 .mk .na \fB\fBlistshares\fR=on | off\fR .ad .sp .6 .RS 4n Controls whether share information in this pool is displayed with the \fBzfs list\fR command. The default value is \fBoff\fR. .RE .sp .ne 2 .mk .na \fB\fBlistsnapshots\fR=on | off\fR .ad .sp .6 .RS 4n Controls whether information about snapshots associated with this pool is output when \fBzfs list\fR is run without the \fB-t\fR option. The default value is \fBoff\fR. This property can also be referred to by its shortened column name, \fBlistsnaps\fR. .RE .sp .ne 2 .mk .na \fB\fBversion\fR=\fIversion\fR\fR .ad .sp .6 .RS 4n The current on-disk version of the pool. This can be increased, but never decreased. The preferred method of updating pools is with the \fBzpool upgrade\fR command, though this property can be used when a specific version is needed for backwards compatibility. This property can be any number between 1 and the current version reported by \fBzpool upgrade -v\fR. .RE .SS "Subcommands" .sp .LP All subcommands that modify state are logged persistently to the pool in their original form. .sp .LP The \fBzpool\fR command provides subcommands to create and destroy storage pools, add capacity to storage pools, and provide information about the storage pools. The following subcommands are supported: .sp .ne 2 .mk .na \fB\fBzpool\fR \fB-?\fR\fR .ad .sp .6 .RS 4n Displays a help message. .RE .sp .ne 2 .mk .na \fB\fBzpool help\fR \fIcommand\fR | \fBhelp\fR | \fIproperty\fR \fIproperty-name\fR\fR .ad .sp .6 .RS 4n Displays \fBzpool\fR command usage. You can display help for a specific command or property. If you display help for a specific command or property, the command syntax or available property values are displayed. Using \fBzpool help\fR without any arguments displays a complete list of \fBzpool\fR commands. .RE .sp .ne 2 .mk .na \fB\fBzpool help\fR \fB-l\fR \fBproperties\fR\fR .ad .sp .6 .RS 4n Displays \fBzpool\fR property information, including whether the property value is editable and their possible values. If you display help for a specific subcommand or property, the command syntax or property value is displayed.
