this will always lead to EIO as it fails to meet the criteria for unify's
functioning.

Unify wants a file to be present only on one of its subvolumes, and in this
case, you have done afr of (v1 v2), (v2 v3), (v3 v1), which means, if a file
is present on (v1 v2) pair, it will be seen by other two afrs too, (v2 in
second pair, and v1 in third pair), so unify sees file to be present on all
of its subvolume, and gets confused which file to open, and returns EIO.

the fix is, you need to export two volumes (instead of currently present 1)
per server, and make pairs of (v1-1 v2-2), (v2-1 v3-2) (v3-1 v1-2),  hope i
am clear
