Hi!
I am running FC3 as mailserver with sendmail+cyrus-imapd and everything works fine. Now I am going out of space on the HDD and I am thinking to add a new one which will server for cyrus only. So how do I tell cyrus to use that other drive instead of /var/spool/imap ?
And also is it enough just to copy this directory to a new location or do I need to do something else like reconstruction or similar.
If you are using LVM, the simplest thing (as already suggested) would be defining additional disk as LVM physical volume. Create partition, tag it as Linux LVM (8e), import it into LVM (pvcreate), add it to existing LVM volume group, and simply grow the logical volume and then /var file system.
Another simple solution would be to mount new disk as /var/spool/imap. Stop the IMAP server and sendmail, mount new disk as /mnt, copy all data, and remount the disk:
# stop imap and sendmail before doing this mount /dev/new_disk /mnt cd /var/spool/imap tar cf - . | (cd /mnt; tar xpf -) cd .. mv imap imap.old # backup copy, remove when not needed mkdir imap umont /mnt # edit /etc/fstab and add line for /var/spool/imap mount /var/spool/imap # start imap and sendmail
When you are happy that all is working, you can delete imap.old directory to free some disk space.
You could have mounted new disk somewhere else and made a symbolic link from /var/spool, however, if SELinux policy files are ever extended to include separate set of rules for Cyrus-IMAPD, they will by default expect mailstore to live in /var/spool/imap. So you'd save yourself some work by having things in defualt places.
