ceph cluster error

ByungJoon — Fri, 29 Aug 2025 14:32:27 GMT

hi,

i created cluster with ceph (HVM 1.2 HCI Ceph Cluster on HVM/Ubuntu 24.04)

during ceph provision, error message occured

2025-08-28T00:07:53.868+0000 7e96c6235740 0 monclient(hunting): authenticate timed out after 300 rbd: couldn't connect to the cluster!

and i edited host file

10.252.2.21 vme01
10.252.2.22 vme02
10.252.2.23 vme03
10.252.2.21 mon.vme01 ceph-mon.vme01
10.252.2.22 mon.vme02 ceph-mon.vme02
10.252.2.23 mon.vme03 ceph-mon.vme03

and ceph.conf

root@vme01:~# cat /etc/ceph/ceph.conf
[global]
public_addr =
public_bind_addr =
# specify cluster network for monitoring TODO Fix
cluster network =
# specify public network TODO Fix
public network =
# specify UUID genarated above
fsid = 256b471d-8b8f-4d2f-8e17-99020530bac6
# specify IP address of Monitor Daemon
mon host = 10.252.2.21:6789,10.252.2.22:6789,10.252.2.23:6789
# specify Hostname of Monitor Daemon
mon initial members = vme01
osd pool default crush rule = -1

# mon.(Node name)

# specify Hostname of Monitor Daemon
host = vme01
# specify IP address of Monitor Daemon
mon addr = 10.252.2.21
# allow to delete pools
mon allow pool delete = true

Did you fix it with this workaround?

There is no need to edit the hostfile or ceph.conf when deploying an HCI cluster.

It seems you are using a single network for management and storage.

What bond/network did you specify for Storage during the creation of your HCI cluster?

Also how does your netplan looks like?

I have 3 network interface: management, storage and compute. My mistakes was that I didn't give an ip address to the storage interfaces on each node. Now preconfiguring the address before deploying the cluster. It works. Thanks a lot.
