mon_command failed - command not known (500)

[Gradlon]

Hey Guys,

I have the following issue with my Proxmox Ceph Setup.

In the configuration section of Ceph I get the following error in Configuration Database.
mon_command failed - command not known (500)

I did not find any meaningful results while searching.
Can anybody help me out?

can you post the output of

ceph status

?

do you have a ceph-mgr running?

what does

ceph config-key dump

say?

I have exactly the same problem. The cluster works without problems but the "Configuration Database" window gives an error
"mon_command failed - command not known (500)"
Proxmox - 6.0-7
Ceph - Luminous 12.2.12

Proxmox - 6.0-7
Ceph - Luminous 12.2.12

that is not a supported setup... pve6 is only intended to work with nautilus (except for the short time when upgrading from luminous to nautilus)

Thanks for your reply! Apparently, the question is removed for me)

 

[Gradlon]

Ok, this solved my problem.
Would have been nice if this was included in the docs of the upgrade process.

Kind regards

you mean like this sentence in the upgrade documentation (https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0)

For Hyperconverged Ceph
Now you should upgrade the Ceph cluster to the Nautilus release, following the article Ceph Luminous to Nautilus.
