To suspend a filesystem, issue the following command on one server that has mounted the filesystem. You must be user root. # /opt/hpcfs/tools/psfssuspend directory_mountpoint 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. You must be user root. # /opt/hpcfs/tools/psfsresume directory_mountpoint NOTE: If an attempt to mount the copied filesystem fails with an "FSID conflict" error, run the following command as user root. In the command, is the psd or psv device, such as /dev/psd/psd1p7 or /dev/psv/psv1, containing the copied filesystem, and is the name that should be used to identify the filesystem. # /opt/hpcfs/tools/psfslabel "" Resize a filesystem manually The resizepsfs utility can be used to increase the size of a PSFS filesystem. (Reducing the size of a PSFS filesystem is not supported.) resizepsfs can grow a filesystem online if the filesystem is mounted on the server where the utility is invoked. Otherwise, the filesystem must be unmounted on all servers before it is resized. The utility has this syntax: # /opt/hpcfs/sbin/resizepsfs -s [+]size[K|M|G|T] [-q] HP Scalable NAS File Serving Software administration guide 153
