I search for this and look what I found in my logs: Oct 27 13:09:09 world kernel: kjournald starting. Commit interval 5 seconds Oct 27 13:09:09 world identd: identd startup succeeded Oct 27 13:09:09 world kernel: EXT3-fs: ide0(3,1): orphan cleanup on readonly fs Oct 27 13:09:09 world kernel: EXT3-fs: ide0(3,1): 5 orphan inodes deleted Oct 27 13:09:09 world kernel: EXT3-fs: recovery complete. Oct 27 13:09:09 world kernel: EXT3-fs: mounted filesystem with ordered data mode So it is working after all. Its just that yesterday, fsck kicked in and I really had to fix the partition manually. I have not noticed any ext3 related text on the screen when my kernel refused to continue the bootstrap because it was asking me to manually fix the partition. So my guess is that journaling works 98% of the time, but once in a while after an uncontrolled shutdown, my filesystem goes seriously kaput anyway, right? >If e2fsck is run on an unmounted fs that has 'needs_recovery' set, it >will also replay the journal. > > > >>My point it that I do not see any difference between ext2 and ext3 >>behavior.

The kernel running on my system is the one installed from the CDROM. I have the source code of the kernel, but not the .config file which corresponds to my running kernel. Anybody knows if it is possible to get the installed kernel .config file so I can check out the configuration? This is off-topic regarding this mailing list, so I suggest anyone responding to this to reply to me personnaly.
