Web UI cannot create CEPH monitor when multiple pulbic nets are defined

Whatever

According to CEPH docs (https://docs.ceph.com/docs/master/rados/configuration/network-config-ref/#id1) several public nets could be defined (useful in case of rdb mirroring when slave CEPH cluster is located in separate location or/and monitors need to be created on different network interfaces/addresses)

Code:
public_network = 10.10.10.0/24, 10.71.200.0/24

However when trying to create mon from Web UI I get an error:

Code:
command '/sbin/ip address show to '10.10.10.0/24, 10.71.200.0/24' up' failed: exit code 1 (500)


Could anyone suggest how to properly create mon in such setup?
Thanks in advance

This seems not to be handled, yet.

Try on the CLI, pveceph mon create -mon-address <IP>.
 
Hello,

I'm in the same situation, the CLI command gives :
root@proxmox1:~# pveceph osd create /dev/nvme0n1
Error: any valid prefix is expected rather than "192.168.1.10/24, 10.0.5.0/24".
command '/sbin/ip address show to '192.168.1.10/24, 10.0.5.0/24' up' failed: exit code 1

any other hint for a workaround ?
 
OK, I could workaround the situation by creating the VLAN interface in the other network 192.168.1.0/24.
I removed the 10.0.5.0/24 entry in the ceph.conf

Thanks !
 
If you are on Ceph Nautilus, the mon_host line needs to exist, then you may remove the public_network to let Ceph auto-detect the networks. But you will need to test, if this work for a service restart.
 
Hi, me again.
Is the patch available in a certain pve version ?
I'm in 6.3-3 and the issue is still present.

EDIT: Looking at the code it seems it is only for mon, and not osd ?

Hello,
I wanted also to create a monitor with the command 'pveceph mon create -mon-address 10.0.15.12'

I still have the issue in 6.3-6

Code:
Error: any valid prefix is expected rather than "192.168.1.10/24, 10.0.10.0/24".
command '/sbin/ip address show to '192.168.1.10/24, 10.0.10.0/24' up' failed: exit code 1

I thought the fix #2422 did fix it for the monitors ?
 
```
root@pve03:~# pveceph osd create /dev/sdf
Error: any valid prefix is expected rather than "10.10.10.10/24 10.10.0.100/24".
command '/sbin/ip address show to '10.10.1.10/24 10.10.0.100/24' up' failed: exit code 1

```
Same in GUI.

do you maybe have multiple entries for the cluster_network in the Ceph configuration? That is currently not properly supported in Proxmox VE, only having multiple entries for public_network is. Feel free to open a bug report so we can keep track of the issue: https://bugzilla.proxmox.com/
