[mythtv-users] XFS RAID Tweaking

[Rob Dege]

Hello,

I just stumbled upon this wiki entry today regarding XFS tweaks, and have a
question about the RAID Array section
(
http://www.mythtv.org/wiki/Optimizing_Performance#Optimizing_XFS_on_RAID_Arrays
)

My system currently uses 2 disks in software raid 0 for /myth.  The
filesystem was built/formatted back in 2007 (when I first built the
machine).  Given that I don't want to reformat the partition, is it okay to
add the custom sunit and swidth values to the mount options, even though
they wouldn't match the values on the partition?

xfs_info on /dev/md0 shows the sunit=16 and swidth=32

The script recommends sunit=128 and swidth=256

Thank you

-Rob
