linux software raid5 on lvm: sunit/swidth required?

[Thomas Molszich]

Hello all,

At present, does one still need to calculate and pass the sunit/swidth to mkfs.xfs or does xfs calculate
All this on its own?
Xfsprogs 3.1.7, linked against libblkid, kernel 3.2.48 (Ubuntu 12.04 LTS), 6x3000GB Hitachi 4k sectors
with 512b emulation, partitions and lvm 4k aligned already.

If manual calculation is still required, where can I read up on that?

With kind regards

Thomas Molszich
