[Dovecot] couple of errors on new setup
I have stood up a new test mail server as an upgraded version of my existing mail server. I have been fairly consistently getting two types of error messages. I'm thinking they may be related permissions issues, but I can't figure out what their problem is.
Oct 4 12:45:47 digory dovecot: imap(guenther): Error: file_dotlock_open() failed with file /home/guenther/mail/ForUs/.imap/Home/dovecot.index.log: Resource temporarily unavailable
Oct 4 12:46:16 digory dovecot: imap(guenther): Error: file_dotlock_open(/home/guenther/mail/ForUs/PCS/.imap/PCS misc/dovecot.index.log) failed: Permission denied (euid=500(guenther) egid=500(guenther), access(/home/guenther/mail/ForUs/PCS/.imap/PCS misc/dovecot.index.log, 4) failed: No such file or directory)
Here are my specifics:
OS: CentOS 6.4 - 2.6.32-358.11.1.el6.x86_64 MailScanner: 4.84.6 Postfix: 2.6.6 DoveCot: 2.2.4 NFS v4 (both the mail spool and /home are NVS v4 mounts to file server)
Here are the non-default settings:
dovecot -n

mbox over NFS has *never* been recommended, it is unsafe - for any pop/imap type server, not just dovecot. If its not too late, and since you are testing a new server it cant be, change to Maildir, it was designed specifically for this very reason.
also should use:
mail_fsync = yes mail_nfs_index = yes mail_nfs_storage = yes mmap_disable = yes

These are never recommended. They may be a kludgy workaround to avoid worst problems, but they will never work 100% In the recommended configurations (one Dovecot server or director cluster) you won't need them.

Ahh OK, thanks, our configs have been carried over since early days when this recommended, certainly never seen any errors with them on our cluster (and we don't use director).
