Hi All, I have an ocfs2 mount point of 3 ceph cluster nodes and suddenly I cannot read and write to the mount point although the cluster is clean and showing no errors.
Are the any other logs I can check? There are some log in kern.log about kern.log Sep 13 08:10:18 nodeB kernel: [1104431.300882] kernel BUG at /build/linux-lts-wily-Vv6Eyd/linux-lts-wily-4.2.0/fs/ocfs2/suballoc.c:2419!
