Re: RAID5 / 6 Growth

["Majed B." <majedb@gmail.com>]

Do any of the disks report sector errors or ATA or read errors?
smartctl -a /dev/sdx should give the report, assuming you run smartd
and have it probe disks periodically.

I've seen newer versions of the xfsprogs and libs packages. Try using
those. I know you're against new packages that haven't been included
in "stable" -- but if this is a dev/backup system, it's worth the shot
in my opinion.

Good luck.
