Reiserfs and ext3 don't need fsck either though do they? Perhaps you
were running early/unstable versions of either ext3 or reiserfs?

In theory yes. In practise ext3 can destroy directories under certain circumstance, reiserfs its whole tree. It happened over the years quite a few times to various people.

Heh, I really hate admitting this, but I lost an entire disk that was running ext3. I'm sure it was something *I* did. However, when every single directory and file ends up in /lost+found, it's hard to figure out what cause it. Of course, praying to the backup gods only works if the person responsible for backups has given them a sacrifice. Arrgh, that was a bad day.


Not to worry. I once had a ReiserFS live for a whole month with no problems. As it was on a rather massive UPS, it might have gone even longer if I hadn't needed the drive for testing Aos.

OTOH, the half-dozen attempts *before* that one never lasted
through either a single hard-read error or a couple of power
outages.  'Good in concept' is ReiserFS, and 'maybe someday..',
but for *now* one best pray to the Gods of harware and power.

And ext2 and 3?  Fewer worries about fragmentation
than MS NTFS, but not as robust if/as/when subjected
to indignities.

XFS and JFS, OTOH, were 'donated' by SGI and IBM. Both
have had scores of years, thousands of man-hours, and
*serious* money invested in development and test.

Both are rock solid, as is MKM's Berkeley FFS --> UFS.

Boot from XFS, use JFS for non-boot storage in the
places it serves better than XFS, and you have the
foundations for as durable a Linux as can be.

For sure it will guarantee a more affordable
'entry price', lots more service revenue, and
an easy upgrade to AIX-5L, which has to be a
large part of the reason IBM love's Linux.

For those of us with a more austere business
model, the *BSD's are a much lighter burden.
