pve5to6 questions

[avbuuren]

Hi ,

i'am using three PM nodes with a ceph cluster. ( PM 5.4.13 and CEPH luminous 12.2.12 )

I would like to upgrade PM 5 .x to 6. x and then, upgrade luminous to nautilus. I read the upgrade procedure : https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0

When i run the pve5to6 script, i have ceph warning ( as you can see on the image) . Should i have to correct this warning before upgrade PM5 to 6 or after ( before the nautilus upgrade)

Thank you.

The ceph.conf is read by service start. And these changes are intended for Nautilus, in the next step of the upgrade.

ok thank you. I upgraded from pve5 to 6 on the first ceph node. Its works but i have an error on the PM interface :
mon_command failed - command not known (500)

I think its normal because i'am in migration procedure, luminous cannot work with pve6 isn't it ?

Can I upgrade my 2 last nodes without consequences on my cluster work?

Thank you.

First you upgrade all nodes to PVE6 and then Ceph. There are Ceph Luminous packages for PVE6.

Can I upgrade my 2 last nodes without consequences on my cluster work?

The cluster should be in a healthy state before upgrading.
