Chapter 7: Configure PSFS Filesystems 94

The mkpsfs Command

The mkpsfs command creates a PSFS filesystem on the specified device,

which must be imported into the matrix. PSFS filesystems use a block size

of 4 KB.

The command has this syntax:

/opt/polyserve/sbin/mkpsfs [-n <max-nodes>] [-l <label>]

[-o [enable-quotas,[userdefault=<size>],[groupdefault=<size>]]

[disable-fzbm]] <device> [<size-in-blocks>]

device is a psd or psv device and is specified as follows:

• For a psd device partition, the device is specified as

/dev/psd/psdXXXpYY, where XXX is the drive number and YY is the

partition number. For example, /dev/psd/psd6p4 specifies partition 4

on disk psd6.

• For a non-partitioned psd device, the device is specified as

/dev/psd/psdXXX, where XXX is the drive number. For example,

/dev/psd/psd5.

• For a psv device, the device is specified as /dev/psv/psvXXX, where

XXX is the volume number. For example, /dev/psv/psv1.

You do not need to specify the full path name. A name such as psd6p4 or

psv1 will work.

mkpsfs requires exclusive access to the device. If it cannot obtain

exclusive access, it will exit with an “ebusy” message.

The arguments are as follows:

• size-in-blocks

The number of blocks on the device. If this value is omitted, mkpsfs

will determine it automatically.

• -n max-nodes

The maximum number of nodes that can be in the cluster.

• -l label

The label to be applied to the filesystem.
