Thanks for confirming this. Yes, I know about the performance impact, but perhaps it's feasible for some setups.
Christian.
PS: I was curious *how* bad the impact was and so I tried generating a 477 MB tarball, first on an async, then on an sync mounted partition:
/dev/md0 /mnt/md0 ext4 rw,noatime,barrier=1,data=ordered $ time tar -cf /mnt/md0/test.tar /usr real 1m36.615s
/dev/md0 /mnt/md0 ext4 rw,sync,noatime,barrier=1,data=ordered $ time tar -cf /mnt/md0/test.tar /usr real 5m23.793s
