[SOLVED] VM not migrated automatically

[Ahmed_F]

Hello,

I have a new cluster with 3 nodes with version 4.4 and trying to get my VM's migrated automatically if the node goes down.
I am using ceph as storage.
I simulated a kernel panic and my VM's didn't migrate.
It there something special I have to do to enable the automatic migration please?

Thank you,

Thanks mate! That helped me alot.
But I noticed that when I add the VM to HA it is not able to start, I got those logs :

task started by HA resource agent

If I remove it from ha, it starts normally.

Any idea please ?

(Sorry I am just starting with Proxmox)

Hi, just to confirm

- live migration works as expected as a starting baseline?
- the ceph storage pool is tagged as type 'shared' in the storage manager WebUI ?

In my experience, if you start with <cluster of 3 nodes> and <live migrate works as expected as starting baseline> then <HA works with very little extra effort>

I just noticed that one of my hypervisor was not well configure with CEPH.
I fixed that issue and now my VM is getting migrated as soon as thee hypervisor goes down.
Thank you for your help
