Hi everybody,
i have two node with drbd in dual-primary mode. On top of this there is
an OCFS2 fs.
I export this whole thing with NFS.
Everything was working fine, i could write on one or another node and
access one or the other with nfs without any problems.
Few days ago (in fact more than few, it was 10 days ago), one node
failed. The node was in inconsistency state but the second node
continued to work read/write. I'm not sure but maybe that even on the
failed node, some nfs clients continued to write.
Today i put back the failed node, drbd resync, and both node were
promoted primary automatically. In fact i had nothing to do.
BUT, i lost all datas which was written between the failure and the
resync. It's like the good node resynced with the failed node and so
reverted 10 days ago (i thought the failed node would resync with the
good node and got all datas written the last 10 days) ! That means i
lost 10 days of data which were here just before the resync.
Is this a normal behavior ??? Is this possible to get back those datas
(i think no...)
So any clues on this would be welcome,
regards,
Guillaume
