3.4.0 Matrix Server Administration Guide

Chapter 7: Configure PSFS Filesystems 94

The next example uses a mount path:

psfssuspend c:\psfs_mount\

The psfssuspend command prevents modifications to the filesystem and

forces any changed blocks associated with the filesystem to disk. The

command performs these actions on all servers that have mounted the

filesystem and then returns successfully.

Any process attempting to modify a suspended filesystem will block

until the filesystem is resumed. These blocked processes may hold

resources, thereby causing other processes to block waiting on these

resources.

When you have completed the backups, use the psfsresume utility to

resume the suspended filesystem. Issue the command from the server

where you executed psfssuspend. Following are some examples.

psfsresume X:

psfsresume c:\\psfs_mount\

NOTE:

If an attempt to mount the copied filesystem fails with an “FSID

conflict” error, run the following command. In the command,

<device> is the partition that contains the copied filesystem, and

<label> is the name that should be used to identify the filesystem.

psfslabel <device> “<label>”

Check a Filesystem

The psfscheck utility looks for a PSFS filesystem on a device, replays

transactions that are to be replayed, and either checks or repairs the

filesystem. The utility can also be used to enable or disable Full Zone Bit

Maps (FZBMs) on a filesystem and to enable or disable quotas or to set

the default quota. Before running psfscheck, be sure that the volume is

not in use.

The utility has the following syntax:

psfscheck [options] device
