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. I am very happy with it. However, I am running out of disk space. It has two times 76Gb Drives in RAID1 (disk mirroring) and the capacity has reached 82%. I am starting of getting nervous. Does anyone know of a painless way to migrate the entire contents directly to another pair of 146Gb SCSI RAID1 disks ? I thought of downtime and using clonezilla, but my last experience with it was questionable. I remember having problems declaring disk re-sizing from the smaller capacity drives to the larger ones.

Andrei,
Thank you very much for you kind reply and both your messages.
Having said that, would it be possible to take away on 72Gb drive (say Drive1 the second drive) and shove in one of the two 146Gb ones ?
Shouldn't the array be rebuilt ? Will it use the extra disk space though ?
Thanks,
spyros
