Running with a full /var/crash partition is unlikely to lead to problems, but may prevent some debugging information from being saved if other issue arises. This alert could indicate that processes may be dumping core and this behavior should be investigated.
You might receive an alert warning that the crash partition of a node in the cluster, /var/crash, has reached 90% capacity. The /var/crash partition is used to store core files from running services that have crashed. This alert could indicate that processes may be dumping core and this behavior should be investigated.
To see what's taking up space in the /var/crash partition, run the following command on any node in the cluster:
isi_for_array -s 'df -h'
isi_for_array -s 'find /var/crash -type f -size +10000 -exec ls -lh {} \;'
If you'd like assistance from Isilon Support to investigate the issue the alert, include the results of the above command in your initial email.
It would also be helpful if we could review the logs from the cluster.
If a core file is filling the /var/crash partition, the file should be saved temporarily to somewhere in /ifs/data/Isilon_Support and the offending service should be investigated for the cause.
A patch might exist for the issue for the specific OneFS version, it might be fixed in a later version of OneFS, or a new bug may be opened for the issue.
