Hello,
We have a 3 node OCFS2 cluster, using:
Kernel: 3.16.0-0.bpo.4-amd64
ii ocfs2-tools 1.6.4-1+deb7u1 amd64
tools for managing OCFS2 cluster filesystems
Today two of the nodes out of the 3 had some partial OCFS2 related kernel panic
(see at the end). After rebooting the first node the FS become available again.
Anyone run into error like this?
