Adding drives to a RAID controller

I have an HP server with 2 raid controllers. One has 2 discs, raid 5 for the sytem partition with 4 free slots and the other has 6 discs, raid 5 for data with no free slots.

The data partition is nearly full. Does anyone know if it is possible to use the spare slots on one controller to add space to the other?

Sorry Grunty, I thought about your problem then failed to reply.

What I might suggest is to ghost the data from RAID sets on the 6 disk controller to larger HDDs, then use old HDDs to make extra RAID sets on the 2 disk controller. Sound feasible?

Me too. I didn't understand how one could run RAID 5 with two discs and still don't. Hopefully, I'm about to get educated. (ya gotta love the educational opportunities here)

 

Thanks for the replies. One of the 6 disks was a spare that I have now added to the array to give another 72Gb which will keep us going for a few months.

After that we will probably look at SANs instead. What I was looking for was a quick and easy way to add more drives to the array which looks like it isnt possible that way.

Rockster - sorry but there will be no education here - I made a mistake, couldnt be RAID 5 with only 2 disks, they are mirrored.
