L2ARC in clusters
Hi,
When deploying ZFS in cluster environment it would be nice to be able
to have some SSDs as local drives (not on SAN) and when pool switches
over to the other node zfs would pick up the node''s local disk drives as
L2ARC.
To better clarify what I mean lets assume there is a 2-node cluster with
1sx 2540 disk array.
Now lets put 4x SSDs in each node (as internal/local drives). Now
