Thanks both for your help. For various reasons, I'll just rely on using
the non-topology aware version.
In the future this lv will be grown in multiples of 256K chunk, 16
drive RAID6 arrays, so am I correct in thinking that the sunit/swidth
parameter can stay the same as it is expanded?
I am thinking that XFS allocates ag's across all the space and that it
will only be writing to any one array at a time, or would there be more
configured if mkfs.xfs were aware that it was being created on say, 2 x
16 RAID6 arrays?
This is based on backing up the first array prior to expansion, adding
the second and mkfs.xfs, as I imagine just expanding the fs over the
second would result in non optimal performance.
