Hi,
for some time now, the following message keeps pooping up in my logs:
> EXT4-fs (dm-1): Couldn't remount RDWR because of unprocessed orphan
> inode list. Please umount/remount instead
I don't know when it started. Maybe 2 months ago, I'd guess. The ext4 fs
is on top of a dm-crypt device, attached via firewire to a 1TB external
disk enclosure. The system (powerpc 32) is loosely following vanilla
kernels, currently running 3.1.0-rc4.
The filesystem is normally mounted r/o but remounted r/w every day to
receive backups, then remounted r/o again. Running e2fsck-1.41.12 with -n
on the r/o-mounted devices gives the output below.
I've unmounted the disk some weeks ago, ran e2fsck for real and it fixed
the errors. But now more errors seem to have occured.
Anyone got an idea why this keeps happening? Bad memory? Bad cables? Disk?
No other hardware related errors are in the logs and the box is otherwise
quite stable.
Thanks,
Christian.
