Re: ext3 filesystem / linux 7.3

FYI, I believe that XFS will be included in the 2.6 kernel.

I don't know how ext3 could be faster than ext2, since it has to do more
work.

But ext2 is not crash-safe.  So your data could well be hosed if you
come back from a crash on ext2.

Actually, I have my doubts about _any_ of the journaling filesystems for
Linux: ext3 has a reputation for being slow if you journal in the
real-safe mode, and there have been so many unrepeatable reiserfs
problem reports that I'm loathe to use it for real systems.  I had
exceptionally good experiences with xfs when I was admining SGI boxes,
but that's not part of the standard Linux kernel distribution, and with
no idea why, I think my managers would get grumpy with me for using it.
