How to move ceph mgr to a specific mgr node

[Ting]

Hi,

I have a ceph cluster with 6 nodes, and 3 nodes has mgr installed, and one (Proxmox2) is active and 2 are standby. I had an active zabbix agent installed on proxmox2, so it will send ceph info to zabbix server and it is working fine. But, every time when I have problem with proxmox2, ceph mgr automatic moved mgr to other node, and proxmox2 will become standby after I resolve issue. then I lost ceph data on zabbix server, I have to stop other mgr node in GUI and force it to move back to proxmox2 (because I have 3 mgr nodes, everytime I have to move twice in order get back to proxmox2)

wondering whether there is a command that will manually to move mgr from one node to a specific node? thanks for your help.

You can use "ceph mgr fail MGRNAME" on the command line to tell Ceph which MGR should not be active any more.
You cannot tell Ceph which MGR to make active in such a case.
