Ok, that's kind of what I thought.
So, for now, with raid5:
- btrfs seems to handle a drive not working
- you say I can mount with the drive missing in degraded mode (I haven't
tried that, I will)
- but no matter how I remove the faulty drive, there is no rebuild on a
new drive procedure that works yet
Correct?
Thanks,
Marc
