Hi All
I'm trying to assist a client who is running out of space.
They have an HP DL360G4 with 2 x 160GB Maxtor SATA drives. they want us
to replace them with 2 x 1TB Seagate drives. They are currently running
everything (apart from /boot) from the root partition and are sitting on
around 97% full.
The problem is their current disk set up.
First disk looks like this:
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 19216 154248097+ fd Linux raid
autodetect
While the second looks like this:
Disk /dev/sdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 254 2040223+ 82 Linux swap
/dev/sdb2 255 19457 154248097+ fd Linux raid
autodetect
As you can guess, /boot is on /dev/sda1 and root is on the linux raid
partition (RAID 1). The RAID looks like this:
mdadm --detail /dev/md0
/dev/md0:
Version : 00.90.01

Number Major Minor RaidDevice State
0 8 2 0 active sync /dev/sda2
1 8 18 1 active sync /dev/sdb2
What is the best way to replace these and allow for expansion later?
Given that I'll end up with 2 x 1TB and 2 x 160GB drives, it would have
been fantastic to use them all with boot, swap and root mirrored at
device level but the bloody stupid DL360 only has space for 2 x sata
drives in total, internally. Added complication is that it is a fairly
mission critical system so whatever we do we have to do it soon and have
it back up the next morning.
What sayest the collective consciousness of the SLUG?
With Thanks and Regards
Nigel.
