mx fs – filesystem commands

Use the following commands to create, mount, or unmount PSFS filesystems,

and to display status information.

Create a PSFS filesystem:

mx fs create [optional-arguments] <storageDevice>

A storage device is a basic or dynamic volume. To locate an available

volume, use the fs showcreateopt command.

The optional arguments are:

[--label <label>]

The label for the filesystem. It can contain up to 32 characters.

[--blocksize <4K|8K|16K|32K>]

The block size used by the filesystem. For a 32-bit operating system, the

block size must be 4K. For a 64-bit operating system, the supported sizes are

4K, 8K, 16K, or 32K. The maximum filesystem size is dependent on the

block size used for the filesystem. The block size cannot be changed after the

filesystem is created.

[--quotas]

Enable quotas on the filesystem.

[--defaultUserHardLimit <unlimited | #{K,M,G,T}>]

The default quota for all users on the filesystem. unlimited specifies that

there is no default. The optional size modifiers specify that the size is in

kilobytes (K), megabytes (M), gigabytes (G), or terabytes (T). If a modifier is

not specified, the size will be calculated in bytes. (The default is rounded

down to the nearest filesystem block.)
