How to clean up an unprocessed orphan inode list?
- by bmk
I tried to mount a formerly readonly mounted filesystem read-writeable:
mount -o remount,rw /mountpoint
Unfortunately it did not work:
mount: /mountpoint not mounted already, or bad option
dmesg reports:
[2570543.520449] EXT4-fs (dm-0): Couldn't remount RDWR because of unprocessed orphan inode list. Please umount/remount instead
A umount does not work, too:
umount /mountpoint
umount: /mountpoint: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
Unfortunately neither lsof of fuser don't show any process accessing something located under the mount point.
So - how can I clean up this unprocessed orphan list to be able to mount the filesystem again without rebooting the computer?
