Well... this thing actually works just fine with a newer kernel ( 2.6.18-8-el5 centos5 ). I managed to mount / mkfs.xfs over raid5 with a pseudo raid5 unit size, and with the appropriate raid 5 patches and user space access-pattern, I elimintaed in 99% cases the read penalty . I sincerly hope I won't be getting any crashes with this file system tunnings. so ... first, chris and all you xfs guys, many many thanks. Chris, How "dangerous" these tunnings are ? Am I to expect "weird" behaviour of the file system ?
