Hello all,

I have yesterday after some typos, sent my ext3 RAID5 array to the void...

I want to recreate it now, but I read on http://wiki.centos.org/HowTos/Disk_Optimization that you can optimize the filesystem on top of the RAID.

Will this wiki article be exactly the same for XFS?

Is it worth the trouble to also create an LVM volume on the RAID array?

You have to understand the details of how the raid was built, stripe size, logical unit number and RAID-5 itself to properly optimize. Google for XFS performance tuning and you'll find lots of details.
