3.4.0 Matrix Server Command Reference

Chapter 1: PolyServe Matrix Server Commands 36

The psfsdq and psfsrq commands should be run in conjunction with the

standard filesystem backup utilities, as those utilities do not save the quota

limits set on the filesystem.

psfssuspend.exe – suspend a filesystem

Synopsis

bin\psfssuspend <mountpoint>

Description

The psfssuspend utility suspends a PSFS filesystem in a stable, coherent, and

unchanging state. While the filesystem is in this state, you can copy it for

backup and/or archival purposes. When copying directly from a suspended

device, be sure to use the raw device (/dev/rpsd/...) to ensure that all blocks

copied are up-to-date.

The filesystem is essentially unusable while it is suspended; however,

applications that can tolerate extended waits for I/O do not need to be

terminated.

The psfsresume utility restores a suspended filesystem. The psfssuspend and

psfsresume utilities affect the specified filesystem on all servers where it is

mounted; however, the utilities should be executed on only one server in the

matrix.

To suspend a filesystem, issue a command in the following form on one

server that has mounted the filesystem.

psfssuspend <mountpoint>

The following example uses a drive letter to identify the filesystem:

psfssuspend X:

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.
