I've read the man page for mkfs.xfs, but I couldn't find out if using
mkfs -d su=64k,sw=2
would be a redundant (and superior) option for that? I'd guess so,
reading the description of sunit:
sunit=value
This is used to specify the stripe unit for a RAID device or a
logical volume. The value has to be specified in 512-byte block units.
Use the su suboption to specify the stripe unit size in bytes. This
suboption ensures that data allocations will be stripe unit aligned when
the current end of file is being extended and the file size is larger
than 512KiB. Also inode allocations and the internal log will
be stripe unit aligned.
Or would I still need to use size=64k?
