Hi,
you are aware of the fact that eql sync replication is just about replication, no single piece of high availability? i am not even sure if it does ip failover itself. so better think about minutes of interruptions than seconds.
Hi Juergen,
I'm absolutely aware that there is no HA discussed here, at least in my mind. It does ip fail-over, but I'm not even blindly trusting it enough, that's why I'm doing numerous tests and measures. I'm gladly surprised by how the iSCSI stack is reacting, and its log files are readable enough for me to decide.
Actually, I was more worrying about the iSCSI reconnection storm, but googling about it does not seem to get any warnings.
This works pretty well with the Eql Boxes, except you use the EQL without Hit Kit. With installed HitKit on each Client i dont think that this will cause problems.
anyway, dont count on ovirts pause/unpause. theres a real chance that it will go horrible wrong. a scheduled maint. window where everything gets shut down whould be best practice
Indeed, this would the best choice, if I had it.
