[Ocfs2-users] OCFS2 crash

[Brian Sieler]

Using 2-node clustered file system on DELL/EMC SAN/RHEL
2.6.9-34.0.2.ELsmp x86_64.

Config:

O2CB_HEARTBEAT_THRESHOLD=30

Kernel param: elavator=deadline (per FAQ)

These log items appear and the server crashes. Has happened twice now
at three week intervals, each time during a heavy IO operation:

Jan 15 16:08:29 db100 kernel: (3898,6):o2hb_setup_one_bio:371 ERROR:

Can't find much on any of these errors…what is 507 ERROR status = -12?

Any help appreciated
