Hi, I have add the new ceph cluster network, do I want to restart in all nodes ? Can I just place the commamd to all 39 nodes? systemctl restart ceph.target

One more question, do you know why no HA enable(no grooups, no resource) , restart the corosync could make the cluseter reboot ?

Umount the folder is ok, Thank you very much !!!!!! Another question, do you know if ceph has ackage updated, does it need the reboot the node ?

Thank you I will try that. But it is difficult for me, there are 39 nodes.

Reboot the node is ok. But I still have many node over 10 nodes have this problem. Reboot is the only option?

It look the same
