To install RAID do you have to rebuild?

[Vini]

I have a server with just one 72GB 10K SCSI drive - do you know if I could add another few disks and upgrade the RAID configuration on the fly? Or would the server need a full rebuild?

I'd image the server, install new disks, build array then image the array.

Depends on your RAID controller

Could do software RAID ie. dynamic disks. That doesn't require reinstall.


....i wouldn't personally tho.

I'd do a fresh install IF it's a new SCSI controller.

If it's not, I'd do what they said..cos Moby knows.

IF you don't mind windows raid then you can do it like this:
Build 2x same sized partitions on new drive, move file over from hdd1 to hdd2, format hdd1 then build 1 partition at half size. Move from hdd2 part2 to hdd1 part1, del hdd2 part2, then use the free space to build RAID0(or RAID5), move the data from non-raid partition to raided partition, then extend the RAID-ed partition to get the whole capacity

...and pray nothing goes wrong

99% of the time you will need to rebuild. Very few controller offer what you want as a feature and they are very expensive.

What server is it?

[Vini]

its a crappy old server. which is due t be replaced. so the radi upgrade can be delayed.
