When the root file system runs out of disk space, it can cause the NetBackup daemons to hang. It will be necessary to stop the daemons and remove logs or other files to reclaim space on the disk. Other applications that run on the system may also be affected.
1. Stop all the NetBackup daemons. This will cancel any queued jobs in the activity monitor:
# /usr/openv/netbackup/bin/goodies/netbackup stop
2. Reclaim disk space on the root file system.
a. The vxlogmgr command can be used to delete older unified log files. This is one possible reason the system can run out of disk space. The following command will delete any log file that is older than 24 hours. If this command fails to remove any logs, then it is also possible to delete individual files from the
/usr/openv/logs directory since the NetBackup daemons have been stopped.
# cd /usr/openv/netbackup/bin
# ./vxlogmgr --del -t 24:00:00
b. NetBackup legacy logging still creates log files in the /usr/openv/netbackup/logs/<process> directory. Check these directories and remove any unneeded log files.
c. Check the system logs and other applications on the system and remove any unneeded files to reclaim space
3. Verify how much disk space is now available on the root file system:
# df -h
Filesystem size used avail capacity Mounted on
/dev/dsk/c0t0d0s0 28G 7.5G 20G 28% /
4. To help prevent this situation from occurring again, lower the logging level for any future backups by issuing the following command. This will set the logging level to one.
To reduce the logging level for unified logging:
# cd /usr/openv/netbackup/bin
# ./vxlogcfg -a -p NB -o Default -s "DebugLevel=1" -s "DiagnosticLevel=1"
To reduce the logging level for legacy logging edit the bp.conf and change the verbose level to
"VERBOSE = 1"
The bpconfig command can also be used to control how many days worth of logs are kept. By default, NetBackup will keep 28 days worth of logs. The following command will reduce this to only five days for both unified and legacy logging:
# ./bpconfig -kl 5
5. Once disk space has been reclaimed, it is recommended to restart the system. Other system processes and applications may have also encountered problems when the system ran out of disk space. A restart of the system will help verify that everything on the system will come up properly after a reboot.
