Re: mounting raid5 with different unit values

[Raz <raziebe@xxxxxxxxx>]

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 ?
