Will RAID have issues with disks that spin down?

Hi. I know that several hardware RAID solutions have issues with disks that spin down when idle; the time to spin back up -- usually on the order of five seconds -- causes unhappy timeouts, etc. I was wondering if that would be an issue with RAID a-la btrfs? Thanks, -Ken -- To unsubscribe

Re: mount errors

1) As of right now, btrfs's fsck is done when it's done. So don't hold your breath, I'm afraid. 2) What errors do you get on mount? It may be as simple as changing your fstab entry such that fsck isn't attempted to be run. (Change the last column to 0.) -Ken On Sat, 19 Nov 2011 14:01:41
