Date: Fri, 20 Nov 2009 13:24:03 +0100 From: Jan Kara <jack@...e.cz> To: linux-ext4@...r.kernel.org Cc: sandeen@...hat.com, tytso@....edu Subject: norecovery option for ext3 Hi, I've tried to test noload/norecovery option of ext3 and I've found it simply does not work. The filesystem does not even mount. There are two problems: 1) the code checking for NOLOAD in ext3_fill_super is simply wrong and ends up failing the mount whenever NOLOAD is set with a message "ext3: No journal on filesystem on <dev>" 2) if one fixes the check, we end up oopsing a few lines below when calling journal_check_available_features() with journal == NULL. Given that nobody used the option (OK, some googling shows that somebody tried to use it in *2.4.9* kernel and it didn't work even there - Stephen Tweedie comments that it's an obsolete option meant for use during fs development) and seeing how badly corrupted the filesystem is when you don't replay the journal, I'd just remove the option. Any opinions?
