Hi,
I’ve added some new nodes to our Ceph cluster. Only did the host add, had not added the OSD’s yet.
Due to a configuration error I had to reinstall some of them. But I forgot to remove the nodes from Ceph first. I did a “ceph orch host rm peon7 --offline —force” before re-adding them to the cluster.
All the nodes are showing up in the host list (all the peons are the new ones):
# ceph orch host ls
HOST ADDR LABELS STATUS
ceph1 10.103.0.71
ceph2 10.103.0.72

peon14 10.103.0.54
peon15 10.103.0.55
peon16 10.103.0.56
But Ceph status still shows an error, which I can’t seem to get rid off.
[WRN] CEPHADM_HOST_CHECK_FAILED: 2 hosts fail cephadm check

Any idea how to clear this error?
# ceph --version
