[lustre-discuss] ZFS based OSTs need advice

[Nathaniel Clark]

I assume you mean, that your storage is active-active and cross-
connected between your OSS's. And you want both OSS to be able to
present any of the 4 OSTs.

Each OST should be it's own zpool, this will let each OST be imported /
failed between OSS's independently.

There's a guide on how to setup Pacemaker v1.1 (default for el7) to do
failover with ZFS and Lustre 2.10+
