Back up and restore membership partitions The membership partitions contain three databases that need to be backed up: • The device database, which contains information about imported disks. • The volume database, which contains information about dynamic volumes. • The mxds datastore, which contains cluster configuration information. The device database and the volume database are automatically backed up to the file /var/opt/hpcfs/run/MP.backup whenever they are changed; your backups of the /var/opt/hpcfs directory will always contain up-to-date copies of these databases. The mxds datastore is automatically backed up to /var/opt/hpcfs/run/ MPmxds.backup once-per-day. If you make configuration changes to the cluster, you may want to make a backup copy of the mxds datastore to ensure that you have an up-to-date backup. Use the following command to back up the mxds datastore to the default backup file, MPmxds.backup: mpdump -X Use this command to back up the mxds datastore to the file of your choice: mpdump -x If the -X option was used to back up the mxds datastore, use the mpimport -X command to restore the datastore to the membership partitions. If the -x option was used for the backup, use mpimport -x to restore the datastore. To restore the device database and volume database to the membership partitions, use the mpimport -f command. The input file is typically /var/ opt/hpcfs/run/MP.backup. For more information about mpdump and mpimport, see the HP Scalable NAS File Serving Software command reference guide. Quotas information for PSFS filesystems The Linux utilities or third-party applications used to back up PSFS filesystems are not aware of the HP Scalable NAS quotas feature and cannot back up the quotas information. Instead, when you back up a filesystem, also use the HP Scalable NAS psfsdq command to back up the quota information stored on the filesystem.
