Thanks for taking an interest. Unfortunately I did have failmode=continue,
but I have just destroyed/recreated and double confirmed and got exactly the
same results.
zpool status shows both drives mirror
of memory on the system.
If ZFS is not beinng used significantly, then ARC should not grow. ARC grows
based on the usage (ie. amount of ZFS files/data accessed). Hence, if you are
sure that the ZFS usage is low, things should be fine.
Hope that helps.
