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.

The lack of a message on the delete operation indicates success. What
you see is the expected behavior, since 'btrfs filesystem show' is
reading the partitions directly. Therefore, it won't see any changes
that haven't been committed to disk yet. The 'some devices missing'
message should go away after running 'sync', or rebooting, or
un-mounting the file system.
