Add disks to existing RAID 1
Posted on 2006-06-04
I need to increase the available storage on a server. The server has performed without fault for a couple of years, so I don't want to screw it up! I need to keep redundancy.
DELL Poweredge 2600 (Service Tag: HG06W0J)
PERC 4i Raid
2 x 36GB SCSI Drives, giving me around 30GB available storage (25GB used)
Redhat Linux 9
RAID 1 config (hardware)
I was planning on purchasing a further 2 x 36 GB SCSI drives.
From the Dell docs, it seems to me that this should be possible.
However, I absolutely DO NOT want to have to reinstall the OS.
I would like to hear from someone who has done this (I can search for docs myself).
Any gotchas appreciated.
How long is the server likely to be offline (25GB used)?
Should I take an image using Acronis or similar (would rather not, because it adds to the time taken)?
