Recommended solution for replace quorum disk

[hermelin]

Hello,
I have to replace quorum disk which is connected throught ISCSI.


Is ok do on running system:
- disconnect iscsi mapped old qdisk - quorum disk to offline
- attach new iscsi location - new disk
- mkqdisk with same name


Is any better/safer solution ?


Thanks for reply

I just finished this up across all my clusters. Removed old iscsi map, added new, create qdisk and then reboot that node. You must leave the old quorum disk up on the node which you arn't making the change on, this way you keep the cluster quorate. Only change the qdisk one node at a time. Good luck!

I have 2node cluster with qdisk. If I change qdisk on first node to new and on secondary still connected old qdisk, I have shortly two different quorum data for cluster until I change secondary node. It isn't problem ?

Not that I came across. I did this very same thing on 10 clusters last week. Some of them were pve 2.x and some of them were pve 3.x.
