The new BSD Magazine with my article is finally out

“Simple Quorum Drive for the FreeBSD CTL HA and the BeaST Storage System by Mikhail Zakharov

During our experiments on developing the BeaST storage system we faced the lack of an automatic LUN failover function of the CTL HA subsystem. Yes, we can switch LUNs with CTL HA, but we have to do it manually setting “Primary role” to the alive controller: sysctl kern.cam.ctl.ha_role=0

We also have to do it fast enough, otherwise, a client host may lose access to the drives of the storage system”.
