By researching on this forum it seems that ext3 is superior to resierfs in performance. So I switched from reiserfs to ext3.

With reiserfs, whenever my system would crash (it's a laptop with a bad battery and if the AC adapter comes unplugged I have about 3 minutes before it dies) it would run fsck at startup and replay the journal and be back up and running in a few seconds.

However, with ext3, fsck takes forever.

Even if I run it manually specifying that it's ext3, it still takes a long time.

How do I force it to replay the journal when fsck is run like it did with reiserfs?

Thanks.

Boot into the LiveCD, and use e.g. tune2fs -l /dev/sda1 to check that you really have a journalled ext3 filesystem. Mine takes seconds to recover after an unclean shutdown.
