No more journalling?! ext3 fs problems

[Steve McGrane]

First make sure that your /etc/fstab still specifies this as an EXT3 FS

If that is the case, remove the .journal file and run:

tune2fs -j /dev/sda4 

to recreate the journal file.

Subject: No more journalling?! ext3 fs problems


Hi everybody,

I have YDL 2.3 Workstation/Development installation running on an ANS 
700/200. Everything works fine, exept for some oddities with ext3 fs.

After installing YDL, I used the script from the YDL 2.3 install CD to 
convert my partitions to ext3. Partition scheme is as follows:

Partition map (with 512 byte blocks) on '/dev/sda'
  #:                type name    length   base    ( size )
  1: Apple_partition_map Apple       63 @ 1
  2:     Apple_UNIX_SVR2 /boot   102401 @ 64      ( 50.0M)
  3:     Apple_UNIX_SVR2 swap    262145 @ 102465  (128.0M)
  4:     Apple_UNIX_SVR2 /      8023705 @ 364610  (  3.8G)

Device block size=512, Number of Blocks=8388315 (4.0G)
DeviceType=0x0, DeviceId=0x0

Mount also gives me the correct values for the filesystems:

/dev/sda4 on / type ext3 (rw)
/dev/sda2 on /boot type ext3 (rw)
...

Now the problem: being forced to hard reset the machine a few times, due 
to some kernel testing, I found out, that sda4 always gets an fsck, 
whereas for sda2 the journal is recovered! Now, I find that the 
filestamp of .journal on / [sda4] is appx. 8 days old. The /boot [sda2] 
directory does not even contain a .journal file.

What happened? Obviously, journalling still works for my /boot partition 
whereas somehow journalling for / has gotten corrupted. How can I fix 
that? Either it is not obvious to me, or it is not that easy to convert 
back to ext2 and then turn to ext3 again in order to get things fixed.

Any help appreciated.

Alex
