RE: [OT] RAID

["Dave Sussman" <davids@xxxxxxxxx>]

I depends upon the RAID card; I've a HighPoint card that doesn't
support
this, nor does it support dynamic resizing of the raid partition. Other,
more expensive cards may support this. I'd just mail the manufactures
and ask them.

I've actually dropped RAID 5 from my server, after a disastrous power
supply problem which caused multiple failures on multiple discs, leaving
me with a completely broken array that wouldn't rebuild. I've now
abandoned RAID altogether on the system drive and am using a small 40Gb
drive PATA drive which I'm imaging using DriveImage; this means it's
easy for me to get back up and running quickly. The data partitions are
all mirrored and I think for home use this is almost better, as if one
drive fails then at least you've a standard usable drive on the mirror.
Ultimately I think I'll use something like drobo for most of my data,
once (if?) they get a NAS version.

I know the subject comes up from time to time.................



Just a theoretical question. Here is the scenario:



Current server is SATA, no raid and one 80gb system drive.



Need/want to upgrade to RAID 5.



So if a RAID card is added and a further 3 more drives are bolted in.

Will the raid (or software) config be clever enough to start spanning
over the 4 drives?

Then could the original 80gb drive be retired.



How do I know the answer to that is going to be 'no' :-).



In other words go from 'no raid' to 'raid 5' without having to copy the
system partition or re-load the OS.
