Hi, Thank you for you response! I have seen the documentation about it and used it in the past, but most of the times there is no problem but 1 of the 10 times it goes wrong and the whole cluster reboots. If possible i wan't to prevent this from happen of course, if there is any way to be more...

Hello, Question, we want to replace some new in the cluster, so remove old node, add new node (and this 6 times). Previous experience we have is that sometimes during the process off adding a new noding something goes wrong and all the nodes will reboot(fence) itself. We wan't to prevent this...

I read in other topics that you also have on each node pvelocalhost in /etc/hosts We don't have it on all nodes, can this be a problem to?

Hello, We want to ad 2 new nodes to our cluster (9 nodes existing), but in the past we had a few times that all existing nodes going to reboot while adding a new node. We don't know exactly what was going wrong because it was going like: - join 6 node > all nodes reboot, after reboot working...

Hello, The problem was with a specific corosync version and a bug in it. corosync: 3.1.2-pve1 https://bugzilla.proxmox.com/show_bug.cgi?id=3672 Also we have disable spanning tree (edge port) on the ports for the proxmox servers, so this ports doesn't flap when the STP topoly changed. We don't...

Ah oké that explains, some difference. thank you.

Hello, I have a question, i read from @tuxis they reach around 2GB/s read speed for verify https://forum.proxmox.com/threads/pbs-scaling-out-storage.97785/#post-430819 The also use normal disks with special devices, just like our situation. 12 x 7200 RPM 8 TB disk (RaidZ2) 2 x 960 GB...

We Use RBD directly, i think the best option in most situations.

Our production Ceph cluster has on this moment: 3 x Mon/MGR Nodes 6 x SSD OSD Nodes 3 x HDD OSD Nodes Currently we are running 9 Proxmox nodes in a cluster which are connected/using to this Ceph cluster. If you have any questions please let me know, always good to share experience.

Hi, We stick to te external Ceph cluster, to not make it more complex then it is. Currently we are looking if we can setup a second cluster as HCI, where we can do a RBD-Mirror for say a disaster recovery. So in worst case we can boot VM's on this DR HCI cluster

pve -v -bash: pve: command not found root@IDC-PVE001:~# pveversion pve-manager/6.4-13/9f411e79 (running kernel: 5.4.143-1-pve) root@IDC-PVE001:~# pveversion -v proxmox-ve: 6.4-1 (running kernel: 5.4.143-1-pve) pve-manager: 6.4-13 (running version: 6.4-13/9f411e79) pve-kernel-helper: 6.4-8...

Hello, I have a strange problem, this is sometimes and not always. We reboot for whatever reason a node (hardware maintenance for example). When the node comes back online all the nodes with vm's with HA enabled are getting rebooted. This is also happend before when we are adding a node to...

oke so i need to do it one by one?

Hello, I used the root user for back-up, but i wan't to change it to a seperate user with the role DatastoreBackup. i found you can change the owner with: proxmox-backup-client change-owner vm/id new-user --repository localhost:datastore But is there some way to change all back-up onwers at...

Sorry for the late reply.. We back-up over 10GB network (actually 2 x 10GB LACP). Back-up source is a Ceph cluster, can this be the problem?

Hello, We are really happy with PBS! Back-up is much faster and we can hold more retention with the incremental/deduplcation function. We have a dedicated PBS server with 12 x 8TB disk en 2 x Enterprise SSD for special device. We currently have set special_small_blocks to 4K, is this the right...

never mind i find that the filesystem contains errors, i wil let it check.

Hello, we are using PBS for a few weeks now, works very nice! Only out of knowwhere we get errors, see bellow, i cannot find anything in the logs what this caused. error message: INFO: 54% (97.3 GiB of 180.0 GiB) in 15m 24s, read: 97.7 MiB/s, write: 41.9 MiB/s INFO: 54% (97.7 GiB of 180.0...

Thanks for the fast response. So if i open only outgoing ports for the PBS on our office location and incoming is nothing possible we are safe. Even if the backups on the PBS in the datacenter are encrypted and this will be synced to our office, then the older back-up versions on this same PBS...

Hello, We are really happy with PBS so far, great product! Question: On this moment we are running a PBS in our datacenter which back-ups all the VM's in the cluster. We want to protect us to for example cryptolockers/ransomware that makes not only the data in the VM unusable but in worst...
