Re: Filesystem

We have been using XFS for about 6 months now and it has even tolerated a
controller card crash. So far we have mostly good things to report about
XFS. I benchmarked raw throughputs at various stripe sizes, and XFS came out
on top for us against reiser and ext3. I also used it because of it's
supposed good support for large files, which was verified somewhat by the
benchmarks.

I have noticed a problem though - if you have 800000 files in a directory,
it seems that XFS chokes on simple operations like 'ls' or 'chmod -R ...'
where ext3 doesn't, don't know about reiser, I went straight back to default
after that problem (that partition is not on a DB server though).
