I am guessing probably su and sw should not be specified and the agcount should be multiple of the number of the concatenated devices, is that correct? 2- Can mkfs parameters be altered after creation, e.g. after growing a RAID and then growing the XFS fs, can I also alter su, sw, agcount somehow? 3- I seem to remember there was an xattr that one could attach to /home (if /home was under XFS) so that every user (subdir of /home) would get a different AG in a different RAID device. I cannot find that information anymore on the internet; could you refresh my mind?
