Hi,
I have a raid1 setup with a missing device. I have added a new device and everything seems to be working fine, except I cannot remove the old, missing, device. There is no error - but the 'some devices missing' tag doesn't go away.

There are a number of sub-volumes of /data that are mounted in other locations. I'm using kernel 2.6.36 (the lucid backport of the natty kernel) and similar btrfs-tools (lucid backport of natty tools). Interestingly looking at the output of `dh -h`, it appears that the 'missing' devices are no longer being counted in the filesystem size - there is just a phantom 'missing' tag in btrfs-show.
Is this actually a problem, or can I just keep running as is? It seems to mount fine without -odegraded.
Any ideas how I can list the missing devices? Any ideas on how I can remove the missing devices?
Be well,
Will :-}
