solved with simply restarting services pveproxy and corosync on the v4.4. machine where the guest-image was. it stills shows the IP instead of the hostname but moving/migration works

I started upgrading from version 4.4. to 5.4 by adding a new host with version 5.4 plan was to migrate old nodes -> new node. upgrade, migrate back, next node etc... I added the new host (debian stretch + pve repos) with # pvecm add $ip_old_44_node --use_ssh 1 result: Nodeid Votes...

thx for the hint. configed the 8th host only to use nfs,ceph and lvm-thin but still cannot see any storage backend. (though the zfs errors in the logs are gone of course). cannot not even see the local storage. pvesm eg. status still hangs (or better runs forever, I can stop it with ctrl-c) did...

node8 logs say (as expected): Jul 10 18:24:23 scalpel pvedaemon[1797]: could not activate storage 'local-zfs', zfs error: open3: exec of zpool import -d /dev/disk/by-id/ rpool failed at /usr/share/perl5/PVE/Tools.pm line 411.

Hi i've got a new 4.4.15 node installed. it's the only node in the cluster (of 8) with no ZFS but lvm-thin. i cannot see any storage on this node. neither in web-gui nor with pvesm status (hangs). is it possible, that i cannot configure a storage (zfs in this case) that is NOT available on all...

realized -> it is allways mon.1 that is reported. this is node pn0002 which really has a different time of ~100ms (see last reply). did a manual resync with the internal timeserver and immediatly after that a date +"%T.%3N" again shows between 50 and 100ms difference... the node has no...

all nodes sync to node dkcpr0001 which is part of the cluster (therefore 1 hop, switched). pr0001 fetches time from some external server

running cssh: root@dkcpn0001:~# date +"%T.%3N" 14:16:05.967 root@dkcpn0002:~# date +"%T.%3N" 14:16:05.888 root@dkcpn0003:~# date +"%T.%3N" 14:16:05.967 don't know if the time difference can come from cssh runtime or the node's load. all nodes sync to node dkcpr0001 which is part of the...

it's regulary, not just after rebooting. e.g. last report was this morning (checks run hourly). all nodes have uptime > 7 days

Hi is it a problem having an even node number (4,6,8,....) for quorum? we have a 4 node cluster where nodes are rebooting erratic (when very high load I guess...) if yes, is incrementing quorum_votes: 1 to quorum_votes: 2 on one node the solution? regards Peter

Hi we have a problem with a 4 node cluster running integrated ceph (meaning nodes are pve and ceph-cluster in one). 3 nodes are ceph mons and osds, 2 of them report: health HEALTH_WARN clock skew detected on mon.1 Monitor clock skew detected we cannot detect why...

Hi ) for testing I installed a PVE 4.2 Cluster with 3 nodes (1 is for quorum only). both are debian jessie with pve-no-subscription repository. cluster works, quorum ok ) configured drbd9 according to https://pve.proxmox.com/wiki/DRBD9 on 2 nodes (redundancy 2) ) drbd is up and running...
