Hi,

I'm thinking of slowly replacing disks in my raid5 array with bigger
disks and then resize the array to fill up the new disks. Is this
possible? Basically I would like to go from:

3 x 500gig RAID5 to 3 x 1tb RAID5, thereby going from 1tb to 2tb of
storage.

It seems like it should be, but... :)

Yes.

mdadm --grow /dev/mdX --size=max

Oh -joy-. I love linux sw raid. :) The only thing it seems to lack is
battery backed-up cache.

Thank you.
