Thanks.

Hi! VM's-disk from local store - on filesystem in file. LVM use for raw format only. Like partition on HDD. Best regards, Gosha

WEB-GUI -> Datacenter -> Storage -> Add -> NFS (for NFS storage). Use DFS as a shared storage for VMs in HA context... May be... if you manual mount DFS as a directory on each node as samba storage, add this directory in WEB-GUI (like NFS-storge but as Directory) and check on Shared option...

Ok. Thanks!

Hi! I want to add a 4th node to the cluster (PVE 4.4), which uses ceph. As I understand it, I do not need to add a 4th monitor. Suffice it to 3 monitors already available? How to properly install the ceph without monitor on the 4th node? 1. pveceph install --version hammer 2. pveceph init...

Yes of course! This old server for testing needs only. (But I'm trying to adapt it for third copies of backups... Just in case... ;) ) I'll try debian packages later and report the results. Best regards, Gosha

Sorry! This is my mistake! This error is related to the configuration my switches for LACP link aggregation. And solved. ;)

Hi! The VMs and CTs ceased to migrate between nodes. For example: I tried the manual ssh-connections between nodes. Does not work! root@cn1:~# ssh cn2 ... and after 2 minutes: Connection closed by 192.168.0.240 root@cn1:~# From my workstation, the SSH connection to all nodes works...
