Hello
I run dovecot 2.0.6 on a two-machine cluster using OCFS2 as the file
system. I have some error messages like these in my log:
Oct 25 01:07:50 box5 dovecot: lmtp(8886,
suporte=100br.com at lmtp1.prv.f1.k8.com.br): Error: Corrupted transaction

These two accounts happen to be accessed simultaneously by a number of
people, but there are similar errors for "normal" accounts too, just not
the same amount of logs. Is it not considered safe to do this kind of
simultaneous access in a distributed filesystem like OCFS2?
Is there a way to fix this error? Would a "doveadm force-resync" do it?
Thanks,
Andre
