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.
CentOS 5.5 Manual install of :
Mysql XMail (pop3/smtp) ASSP (anti spam) Apache / LAMP and last but by no means list : Dovecot <SNIP>
It really depends on the raid you have. is it software or hardware raid? if it's software raid it will be more then simple to do it while taking one drive out put a new one in and use let say FINNIX linux from cd\dvd\usb and manage the whole partitioning copying etc from another OS while not harming anything in the old HDDs. you will might need to setup a new partitions manually on the new drive but just make a plan try it on some small VM to make sure the steps you are doing are fine for centos 5.5 and go for it.
rsync is your friend!! in this case.
someone mentioned here Gentoo which one installation of the system can give you very big backgorund on manual partitioning chrooting and other basic stuff that can help you in the process.

Any help would be appreciated or any ideas you might have.
