Hi,
we have just installed our new Open-E 7up54 with active-active iSCSI clustering. After testing we just put it in productive environment some days ago.
Now I see there is a up56 with new features (especially the one about modifying cluster settings in HA mode). Now my question: can i do an update without downtime by just move all resources to one side and update one side and afterwards updating the other side?
if i'm going to disable HA all vm's and applications on our cluster will die. so there should be a way to do an update without downtime. i can't find any documentations about how to do a correct update...
