Upgrading RAID 5

Hi!

I have 3 disks of 16 Gb on a LC2000 in RAID5 config. I'm going to buy 3 more disks and I want to upgrade my space. Is there a way to do this smoothly? Like, remove 1 disk of 16 and put a bigger one in is place and then remove other, and other until replace them all? Leting, of course, in between the Rebuild of information!

If not, how can I do this with the minimal problems for my system?

Vitor,

All drives in the raid 5 array need to be the same size, so no you can't do that. You should have room to add the 3 additional drives, I'm not familar with the LC2000, if it's similar to the Compaq offerings, how much room you have may depend on the width of your current drives (1.6" vs 1"), in any event if the 3 new drives can be installed, you should be able to create another raid 5 array, once you create logical drives, the OS should see them and allow you to format them. You can simply use the additional space, allowing you to keep your existing space, at a latter date, when you need even more space, you can replace the original drives.
