Description of problem:

Comment 1 Mikuláš Patočka 2008-06-11 03:12:57 UTC 
Resolving this as WONTFIX because Ext2 design doesn't allow stabilizing the
filesystem while it is mounted. See explanation in bug 178705. There are two
major problems with it:

1. You can sync, but you can't prevent any concurrent updates while the sync is
in progress. Preventing concurrent updates would mean to add another lock to Ext2
and would kill performance.

2. Ext2 doesn't provide a method for removing open deleted inodes. The only way
to remove them is to run fsck.
