Subject: Kernel Bug after corrupted filesystem
Date: Tue, 30 Dec 2008 14:19:53 +0100 [thread overview]
Message-ID: <20081230131953.298540@gmx.net> (raw)

Hi,
I am experimenting with nilfs2 for a while now, because I like the Idea of this filesystem. The filesystem I have problems with now is a more complex problem. I used just for testing purpose a file on an ext3 filesystem as a cryptoloop device and I used nilfs2 on the loopback device. It worked for about half a year without a problem. But I have no Idea what was actualy going wrong (ext3 problem, cryptoloop problem, nilfs problem?) and I don't know if a filesystem under normal conditations get corrupted like this (actualy no real data loss either, because almost all files existed elswhere)
But when I now try to mount the nilfs2 filesystem it does not work. No result from the mount command, but the attached in dmsg. The system is still useable, but I am not able to shut it down (have to hold power button 3 seconds). And I am not able to unload the nilfs module either (is in use)
Hope this helps to further improve nilfs2.
