raid 5

[therealtalkinggoat]

i have a raid 5 system that has 6 120gb (640gb) disks. i want to up the size to 256gbs (1.28tb). is it possible to put larger disks in one by one without loosing any data? can i just replace the disks one by one? if i do so, would it see the extra space when i replace the final disk? i'm betting that it won't, so don't think that by saing it won't work you are going to hurt my feelings

thanks
chris

I will assume this is a D-Series type disk. You could actually upgrade by installing one disk at a time and waiting for the rebuild to happen before changing the next disk. The array will see the extra space but will not be added to any LUN. It will be extra space in that volume group. You could then create an additional LUN from there.
