Fabian, It's the same issue with multiple VM's, running on multiple physical servers. But in the case of the last VM I tried: root@host02:~# pveversion -v proxmox-ve: 4.2-48 (running kernel: 4.4.6-1-pve) pve-manager: 4.2-2 (running version: 4.2-2/725d76f0) pve-kernel-4.4.6-1-pve: 4.4.6-48...

Silently bumping this thread... I surely can't be the only one running into this?

What happens as well is that the VM get's restarted when the storage migration fails. Disabling HA for the VM doesn't help - the VM is stopped when the migration fails.

Hi all, I'm trying to migrate disks between 2 storage endpoints. Both are NFS, but on different storage arrays. Both storage arrays are almost idle. This is the error, after 100% migration flow: TASK ERROR: storage migration failed: mirroring error: VM 255 qmp command 'query-block-jobs' failed...

Yes, they are.

Nobody ran in to this problem yet? Is there a way to temporarily stop the fencing process?

Hi, I have a proxmox cluster running with 13 nodes. I wanted to add a node to it. Somehow it then decided to restart all running VM's. All 200-something VM's were restarted. Finally all VM's come back online, I see the 14th node in the cluster, but it appears offline, as is one other node. The...

And above instructions have to be done on each node?

Hi Wolfgang, Found that URL myself, but it only speaks of removing a single node. Is it as simple as deleting all nodes one by one from our "master" node?

Hi, Due to some failures we have a non working cluster. How can I completely destroy the cluster configuration on all 3 members to I can recreate the cluster? The machines have containers running, so I can't reinstall the machines alltogether.

Thanks, works like a charm.

Hi, What is the easiest way to completely disable the firewall from command line, the "proxmox way" ? Someone f*cked up the firewall config and we don't have access to the web interface any more and cluster config is broken.

Hi, In oVirt we're used to configuring affinity groups, i.e. web1 & web2 can never run on the same node. Is such a thing possible in Proxmox? Thanks!

I added a few more nodes today. On one of the nodes I'm seeing the same issue: can't migrate from one specific node to another. Also in this one the output of pvecm nodes contains an IP instead of a hostname. How to fix this? Put hostname for each machine in hosts file?

Ah, that part was unknown to me. However.. I have a 192 GB host, 53% RAM in use. KSM is not used. I'll put some more VM's on it to see what it does.

Hi all, On my currently 7 node cluster I see on all nodes that KSM sharing is 0. Is there a setting I have to make to enable KSM sharing? 90% of my VM's are the same OS, on the old platform (oVirt) we did see KSM sharing active.

I've been able to isolate the problem further. I can't seem to migrete from one specific node to this new node. The difference between this node and other nodes is that in "pvecm nodes" I see an IP for the node I can't migrate to. On the other nodes I see a hostname.

Yes, all nodes are the same, running the very latest version.

Hi, I just added the 5th node to my proxmox cluster. All seems well. It's shown as online in the interface, I can interact with it from the interface (create VM's). However .. I'm not able to migrate VM's onto it. It tells me "no such cluster" node after picking it from the drop down menu...
