I might misunderstand the behaviour of rsync. I thought it operats - create a temporary empty file, get a new inode - write latest contents to it - rename it to the original name, old file is removed But according to your experience, rsync seems to operate - open and truncate a file - write latest contents to it So the inode number is unchanged. I am afraid that the "Deleted inode XXXX has zero dtime" msg in your fsck log made me misunderstood. Now I'd ask you "Who deleted what?"

I meant - run your rsync script - before you shutdown your system, remount ext3 as readwrite - and shutdown J. R.
