stratis is a command-line tool to create, modify, and destroy Stratis pools, and the filesystems allocated from the pool.

Stratis creates a pool from one or more block devices (blockdevs), and then enables multiple filesystems to be created from the pool.

--version

Show stratis-cli version.

--help, -h

Show help on command.

--propagate

(For debugging.) Allow exceptions raised during execution to propagate.

pool create <pool_name> <blockdev> [<blockdev>..]

Create a pool from one or more block devices, with the given pool name.

pool list

List all pools on the system.

pool rename <old_pool_name> <new_pool_name>

Rename a pool.

pool destroy <pool_name>

Destroy a pool and all the filesystems created from it.

pool add-data <pool_name> <blockdev> [<blockdev>..]

Add one or more blockdevs to an existing pool, to enlarge its storage capacity.

pool add-cache <pool_name> <blockdev> [<blockdev>..]

Add one or more blockdevs to an existing pool, to be used as a cache instead of additional storage. Typically, smaller and faster drives, such as SSDs, are used for this purpose. NOTE: There is a temporary restriction on the total size of the cache device of 32 TiB. Adding devices to the cache so that the cumulative size of all the devices in the cache exceeds 32 TiB will result in an error.

filesystem create <pool_name> <fs_name> [<fs_name>..]

Create one or more filesystems from the specified pool. NOTE: There is a temporary restriction on the number of filesystems that can be specified with this command. Specifying more than one filesystem will result in an error.

filesystem snapshot <pool_name> <fs_name> <snapshot_name>

Snapshot the filesystem in the specified pool.

filesystem list [pool_name]

List all filesystems that exist in the specified pool, or all pools, if no pool name is given.

filesystem destroy <pool_name> <fs_name> [<fs_name>..]

Destroy one or more filesystems that exist in the specified pool.

filesystem rename <pool_name> <fs_name> <new_name>

Rename a filesystem.

blockdev list [pool_name]

List all blockdevs that make up the specified pool, or all pools, if no pool name is given.

daemon redundancy

List the redundancy levels that the Stratis service supports.

daemon version

Show the Stratis service’s version.

STRATIS_DBUS_TIMEOUT

Sets a timeout for any Stratis D-Bus call. If this environment variable is not set, a default value of 120 seconds is used for the timeout. The accepted STRATIS_DBUS_TIMEOUT environment variable values are:

1. an integer between 0 (inclusive) and 1073741823 (inclusive), which represents the timeout length in milliseconds
2. -1, which represents the libdbus default timeout

If a block device appears to be already in use, stratisd will refuse to claim it. To allow use with stratisd, any signature on the device must first be erased. Please carefully verify the identity and availability of the device before taking such a step.

Example 1. Creating a Stratis pool

stratis pool create mypool /dev/sdb /dev/sdc

Example 2. Creating a filesystem from a pool

stratis filesystem create mypool data1
