i am barely new to this issue. What would you xfs guys recommend me?
i prefer things i can do with kernel, so its dm-cache? bcache?

the raid is an raid5 with 3 disks at moment. xfs filesystem.
do i have to format it again and set special things?

i use nobarrier at moment,

any hints or links or guides or even tipps from you directly would be 
great,


thanks
