View Full Version : [xubuntu] Converting system to RAID 1

June 27th, 2008, 10:21 PM
I have a new Xubuntu system and am wanting to make a RAID 1 for the documents stored in the /home folder. Contains users and clients documents.
So I have two identical SATA drives. one contains the data and the other is new and currently unused (it actually is formatted as ufs2 from a BSD system I shutdown). I have been looking up an down for tips on building a RAID 1 in this scenario...and havn't had any luck.
Does anyone have any such links or instructions to help me out.

I have:
sda1 /
sda... other partitions on sda

the two identical drives are:
sdb1 /home
sdc1 /mnt - the ufs drive mounted read-only temporarily

Hmm. doesn't look I have the hardware for fakeRAID. I don't think I have a SATA raid controller...

I have looked at mdadm...seems I need to repartition and reformat the disks to "use for RAID" and then put the data

Well. I'll have to restore the files from backup after I do all this.

Am I right? I need to use parted and redo sdb and sdc as a volume for RAID. and then reformat each as ext3. And then create the RAID 1 and then put on the data?

Would it be possible to just set sdb as RAID first, then create the RAID 1 in a crippled mode. Copy over the data from sdc. format sdc as RAID, then insert it into the RAID 1?

I managed by following these instructions essentially:
