Is CentOS using ext2? I thought everyone moved to ext3 already, which
provides nearly the speed of ext2+async but is safe due to its journal.
If you make such comparisons, please use current technology, and not
the status quo of 5 years ago.

[Apart from that, over the last decade, I've lost more UFS filesystems
than ext2, so at least for me, that purported unsafety of ext2+async
mounts is theoretical at best. In the end, with today's write-caches
usually enabled, both are essentially the same, anyways.]

mkb.
