Ow, I have an Idea , if you are using domain name in your cluster , check /etc/hosts on all old nodes: ssh: vi /etc/hosts or nano /etc/hosts <- add new nodes , old nodes and NAS should be already there on all new nodes: ssh vi /etc/hosts or nano /etc/hosts <- add old nodes, rest new nodes and NAS

We don't know yet what nas box do you have, so check in the meantime, with how many iSCSI Target Volumes it can work at the same time. Or how many targets in NAS config can be assigned to this Share Target.

1. Did you join this new hosts to cluster ?: - ssh on new host1: command: pvecm add X.X.X.X <- this should be ip of master host for this cluster - ssh on new host2: command: pvecm add X.X.X.X <- this should be ip of master host for this cluster 2. All nodes have the same proxmox version ...

I thought about it, but in this configuration proxy will be point of Failure.

Thanks Dietmar, You save my time. I close this Topic.

cjw, don't forget configurate failover domains before, read this https://fedorahosted.org/cluster/wiki/FailoverDomains and then look on this part of my config: important for good working fencing is fence ip should be in diffrent subnet like nodes.

Thanks Dietmar, for you reply. I know ext4 is better like ext2, but this isn't sens of this problem, I need live-migration for VM when node goes down, or maybe something like "VM redundancy" or "Node redundancy". Maybe i didn't explain good this what i want before. So i try again: I start VM...

My config look like:

File system for VMs , HA->add NFS-> NFS Located on External NAS ( NAS is in the same subnet like Nodes ) disk image is qcow2, VM works with three partitions ext2(system), swap, ext4 (rest).

Check whether you have set the permissions on the NAS for this new hosts

Hello everyone, What I would like to do: I have 3 nodes i HA cluster, configured with fence and failover domain, storage on external NFS. When node fails, then VM migrate on next node and starts up, every think works fine, but when VM (restarts) starts up, then every time linux installed on...
