4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 2010)

With sparse-fullcost, quota accounting for sparse files reflects the virtual
size of the files. With sparse-realcost, quota accounting for sparse files
reflects the actual allocation of filesystem space to the files. sparse-realcost
is the default.
The mx command
To create a filesystem, use this command, where storage device is a basic or
dynamic volume. Use mx fs showcreateopt to locate an available volume.
mx fs create [<options>] <storageDevice>
To reformat a filesystem, use this command:
mx fs recreate [<options>] <filesystem>
The options for mx fs create and mx fs recreate are:
--label <label>
The label for the filesystem. It can contain up to 32 characters.
[--blocksize [4K|8K|32K]]
The block size used by the filesystem. If you are using HP PolyServe Software
for Microsoft SQL Server, the block size must be 8 KB.
[--reuse]
This option applies only to mx fs create. Reuse a psd device. If you will be
creating a filesystem on a psd device that is associated with an unimported
volume, the -reuse option must be used to tell the command to reuse the device.
Without this option, the attempt to create the filesystem will fail because the
device contains a volume signature. Be sure that you do not need the unimported
dynamic volume before doing this.
--quotas
Enable quotas on the filesystem.
--defaultUserHardLimit <unlimited | #{K,M,G,T}>
The default hard limit 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.)
[--defaultUserSoftLimit <unlimited | #{K,M,G,T}>]
The default soft limit. unlimited specifies that there is no default. The optional
size modifiers specify that the size is in kilobytes (K), megabytes (M), gigabytes
