3.5.1 Matrix Server Command Reference

Chapter 2: mx Commands 71

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

The default quota for all groups 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.)

Recreate a PSFS filesystem:

mx fs recreate [optional-arguments] <storageDevice>

The optional arguments are the same as mx fs create.

Display information about available volumes:

mx fs showcreateopt

Mount a PSFS filesystem on the specified servers:

mx fs mount

--path

<path>

[

--persist

] [

--activate

] [

--options

option,option,...

<storageDevice> ALL_SERVERS|<server>

...

The --persist argument causes the filesystem to be mounted automatically

whenever the server is rebooted. The --activate argument mounts the

filesystem now. The --path argument specifies the directory mountpoint for

the filesystem; if this mountpoint does not already exist, include the

CREATEDIR option to create it.

The mount options are:

RW/RO

Mount the filesystem read-write or read-only. RW is the default.

ASYNC/ SYNC

ASYNC

, the default, allows either asychronous or synchronous I/O to the

filesystem.

SYNC allows only synchronous I/O.

DEV/ NODEV

Interpret (or do not interpret) character or block special devices on the

filesystem.

DEV is the default.

EXEC/ NOEXEC

Permit (or do not permit) the execution of binaries on the mounted

filesystem.

EXEC is the default. NOEXEC can be used on a system that has

filesystems containing binaries for other architectures.
