Dovecot Version 2.2.13
Linux Distribution: Debian Jessie
CPU Architecture: x64
Filesystem: GlusterFS/NFS, XFS for Base System/Index Files.
Two Dovecot/Postfix nodes accessing same GlusterFS/NFS Maildir.
Regardless what i choose in mail_location (:INDEX=MEMORY or
:INDEX=/var/indexes/%d/%n) all Mailbox index files will still get
created within the users mail_location maildir: ~/Maildir
My mail_location Maildir directory is shared on GlusterFS mount so i
need to get index files away from this share due locking mechanism and
faster caching.
The weird is, if i set INDEX to /var/indexes, the index files getting
created sometimes but then not updated frequently and exist parallel on
Maildir which are mostly newer than on /var/indexes. If you delete the
dovecot.index* files from Maildir, they will get recreated immediatly on
Imap access but not on the alternative set INDEX location, they are
getting recreated within Maildir again.
Here is doveconf -n Output:
