Adding new Ceph OSD when using multiple Cluster LAN IPs

[Lars Friedrich]

We had problems adding disks as new Ceph OSDs

pveceph createosd /dev/sdX
Error was: command '/sbin/ip address show to '192.168.1.201/24 192.168.1.202/24' up' failed: exit code 1

The workaround was to teporarily deactivate the 2nd Cluster IP in /etc/pve/ceph.conf
cluster_network = 192.168.123.201/24 #192.168.123.202/24

After adding the OSD, 2nd cluster Ip was added, again without problems.

Any tips or comments?

The cluster_network has to be a network address, e.g. 192.168.123.0/24 and not an interface or host address.
