Ext3 users - Sep 2001 - Why is .journal file sometimes visible and sometimes not?

Hi.

I recently migrated two machines from ext2 to ext3. Kernels (nearly 
identical) are 2.4.9-ac9 + preemptivity-patch + wrr-patch. The Installations 
are based on Mandrake 7.2 + 8.0. Also I have e2fstools-1.23 newly compiled on 
them. Both machines have two ext3 partitions (root + multimedia-data). On one 
machine I see a .journal file on both partitions, on the other machine 
(Mandrake-8.0) it's only visible on the root-partition. Journalling works 
flawlessly and 'cat /proc/mounts' shows ext3 for all. What does this 
inconsistency mean?

Marcus,

tune2fs tries to create a hidden journal file whenever possible.  If a 
filesystem is mounted, though, doing so is apparently unsafe, and 
tune2fs creates a .journal file instead.  The two "modes" are 
functionally equivalent as far as I can tell.
