Subject: metadata_csum + unclean shutdown = failure to boot
Date: 7 Oct 2012 01:04:27 -0400 [thread overview]
Message-ID: <20121007050427.6711.qmail@science.horizon.com> (raw)
Feeling a bit adventurous, I enabled metadata_csum on many of
my daily-use file systems.
I have now noticed a problem in the event of an unclean shutdown.
On reboot, the kernel complains about a bad superblock checksum, suggests
e2fsck, and then fails to mount the root filesystem.
This makes running e2fsck a bit problematic.
I can fix it manually, but it makes automatic reboots *extremely*
problematic.
Is it possible to fix the kernel code to be a bit more forgiving?
