We are running Dovecot 2.0.12. It runs on only one server and /var/mail
is local where all the INBOX's are stored. Users other IMAP folders are
NFS mounted on the server.
We see frequent
Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy
I know this error message has been around a long time. Should we still
be seeing it on 2.0.12 with a local /var/mail. Perhaps the message is
misleading and really complaining about folders other than INBOX that
are NFS mounted.
Our config has
dovecot.conf:mail_nfs_index = no
dovecot.conf:mail_nfs_storage = yes
is that correct given the above?
Also, does the flush error messages have any real consequences? My
understanding is that the rmdir is meant to fail, just to force a flush.
