Hello Spyros, As "best practice" you never have the OS and the data/logs/user homes on the same partition or set of disks.
If this is the case then your life is pretty easy: -simply create the new set of partitions -mount the new ones in a temporary location -rsync (or copy everything from old partitions) -Stop dovecot / all other daemons that might be using the data -mount the new ones in the place of old ones, mount the old ones in the place of new ones - rsync again (should be quick as not many things changed) - start all your deamons again :P If you do not have separate partitions maybe this is the perfect time to look into that... I would also look into btrfs... might be a good pick for your new partitions. best regards, Andrei > Hello all, > > I have a DL360 G4 1U server that does a wonderfull job with dovecot horde, > Xmail and OpenLDAP for a company and serving about 40 acouunts. > > The machine is wonderful.
