RE: [Xen-users] XCP pool-ha-enable
Hi,
XCP doesn't have a complete HA implementation: it's missing a host
heartbeat/liveness service. HA enable will fail when xapi tries to start this
daemon.
Re: the SR: Normally storage plugins are called while xapi is running normally
and the pool-wide database is available. HA requires a shared disk and this
disk must be attached before the pool-wide database is available. There are
special operations for this ({generate,attach_from}_config IIRC). These are
implemented by the LVMoISCSI and LVMoHBA SRs but not currently by the ISCSI SR.
Cheers,
Dave
