you need the eql hit kit to make it work at least somehow better, but
hit kit requires multipathd to be disabled which is an dependency to ovirt.

Hi,
you are aware of the fact that eql sync replication is just about

it does ip failover itself. so better think about minutes of

Hi,
since some time we get Error Messages from Sanlock, and so far i was not

its something which can be ignored or needs to be fixed (and how).

most dont

- FreeBSD ctld iscsi-target + Heartbeat -> same

Generally, avoid mode 0 - Round Robin or you will face problems sooner
or later. RR will generate TCP out of Order.
Go for mode 4 / lacp wherever possible
