Last updated on JANUARY 08, 2018
Applies to:Linux OS - Version Oracle Linux 6.6 and later
Information in this document applies to any platform.
On Oracle Linux 6.6 nodes, commands like rm, ls, df, etc on a particular directory in an ocfs2 filesystem hang.
This issue is seen on all the nodes where that particular filesystem is mounted.
Cluster wide locks are blocked by the nodes and 'quota'(dquot*) threads are seen to be blocked in the vmcore generated by forcefully crashing the system.
