hello,

Before the repair process, xfs_repair will check if user specified device already
has a writable mountpoint. And it will stat all the mountpoints of the system. If there
is a dead mountpoint, this checking will be blocked and xfs_repair will enter 'D' state.

So why is the mount point dead?

That kinda means that the filesystem is still mounted, but something
has hung somewhere and the filesystem may still have active
references to the underlying device and be doing stuff that is
modifying the filesystem....

And if the device is still busy, then you aren't going to be able to
mount the repaired device, anyway, because the block device is still
busy...

That sounds like a bug worth fixing, but I am much
less excited about adding options which could do serious damage
to a filesystem.

TO me it sounds like something that should be fixed by a reboot, not
by adding dangerous options to xfs_repair...

Cheers,

Dave.
