Hi All,
We recently moved from RHEL6 to RHEL7 and updated dovecot from dovecot-2.2.10-1_14.el6.x86_64 to dovecot-2.2.36-8.el7.x86_64. We use NFS for storing the mail, and 5 servers running at the same time. Before updating dovecot we stopped the service and deleted all dovecot.index* files Now we're experiencing some problems. For example, when deleting an email it is note deleted and appears again duplicated. These are the logs:
Feb 28 08:50:42 server5 dovecot: imap(user@domain): Error: Index path/Maildir/dovecot.index: Lost log for seq=5 offset=228: Missing middle file seq=5 (between 5..4294967295, we have seqs 4): Log is locked - newer log can't exist (initial_mapped=1, reason=Index mapped) Feb 28 08:50:42 server5 dovecot: imap(user@domain): Warning: fscking index file path/Maildir/dovecot.index Feb 28 08:50:42 server5 dovecot: imap(user@domain): Error: Failed to map transaction log path/Maildir/dovecot.index.log at sync_offset=10328 after locking: pread() failed: Stale file handle Feb 28 08:50:42 server5 dovecot: imap(user@domain): Error: Index path/Maildir/dovecot.index: Lost log for seq=5 offset=228: Missing middle file seq=5 (between 5..4294967295, we have seqs 4): Requested newer log than exists - still after NFS flush: Log inode is unchanged (initial_mapped=1, reason=Index mapped) Feb 28 08:50:45 server5 dovecot: imap(user@domain): Error: Failed to map transaction log path/Maildir/dovecot.index.log at sync_offset=10328 after locking: pread() failed: Stale file handle Feb 28 08:50:45 server5 dovecot: imap(user@domain): Error: Failed to map view for path/Maildir/dovecot.index: Missing middle file seq=5 (between 5..5, we have seqs 4): Requested newer log than exists - still after NFS flush: Log inode is unchanged
Usually restarting the email client solves the problem for a while. We've tried deleting the indexes but it happens again some time later.
This is dovecot config:

Can you please help me? Thanks in advance and best regards

Hi!
Are you ensuring that the same user is not concurrently being accessed by multiple backends. All mail sessions for a user, including mail delivery.
Are you using NFSv3 or NFSv4?
