First, thank you for your help... So at the same time I upgraded to 8, I added two additional nodes. Both of those nodes were totally fresh, bare-metal installs, and then they were added to the cluster. I have tried the CT on every node in my cluster and regardless of which node I put it on...

So, I am running a 6-node cluster, a 10GB dedicated backend Corosync network with no other traffic, and a 10GB frontend network dedicated to various VLANs and networks to run our VMs/CTs. Also running PBS for backups. 20GB bonded link to that system running 802.3ad. I have a business dedicated...

In case anyone runs across this thread, I determined the problem. It was a single LXC container running Turnkey Core (16.1) as a media docker LXC. It had been running fine for several years, but I think when I updated Proxmox from 7.4 to 8.0.4 this caused an issue. It took some time to figure...

I have a 6-node cluster that I recently (two nights ago) upgraded to 8.0.4. This cluster has been going strong with no issues at all until after the upgrade to 8.0.4. The upgrade went smoothly with zero issues at all. Now, one node in the cluster keeps 'greying out' on the GUI. I rebooted the...

Hello Everyone - We currently have a 4-node cluster running on Del R820s, each with 4 x E5-4650 2.7Ghz CPU, 256GB RAM, 10GB NICs, and mirrored SSD drives for VM/CT and NFS for other storage. We run Cisco Nexus 10G switching as our backend corosync separately from our 10G frontend. These...

Just a follow-up in case anyone runs across this, that was the issue, one of the systems had a different version on it somehow and after upgrading them all to 7, everything works again!

Thank you so much for your help, they were all installed at the same time but something obviously got upgraded on the one! I will work on upgrading the rest of the nodes one-at-a-time and let you know if that did the trick. Thank You again for your timely help and direction!

Thank you @Fabian_E OK, I have four systems, all of them were built and put into production the same day, all of them have been updated continually, and an apt update on all systems show them up to date. Of the four systems, replication is working as expected except that the 4th system (aptly...

I have a four-server cluster running HA and replication. I have multiple replication jobs running and most of them are replication just fine, but I have several that continue to fail with the following output and I cannot figure it out. I have deleted the replication jobs, readded them all to no...

Everything is the latest version, these are brand new installs. All OSs are affected across both cluster nodes but only on migrated VMs and CTs. If I create it from scratch on the node, the problem does not happen. Where is the journal, I will take a look.

The dmesg is from the host, not the proxserver, and yes, this happens to a host that is stopped, backed up on one Proxmox server, and then restored to the new Proxmox cluster and restarted. All proxmox servers store (and run) the images off locally attached NVMe or SSD ZFS storage. I backup the...

Hi Mira - I have a three-node cluster. Two of the nodes are Dell R820, 4 x CPU, 256GB RAM, 2 x HGST 12Gbs SAS SSD (OS) in a ZFS Mirror on an LSI 3008 IT mode HBA, 2 x Intel P4500 Series NVMe drives (4TB EACH) also in a ZFS mirror, these plug directly into the motherboard PCI slots as they are...

Hello Community - We built a new proxmox cluster (3 node) and started migrating VMs and CTs from an existing Proxmox single node unit to the cluster. I keep having issues with these nodes crashing with weird filesystem and mount errors. They run perfectly fine on the old proxmox unit and w are...

Hello - I have a very weird issue I am trying to solve. I had a stand-alone promox server that has been running fantastic for quite some time. We decided to move to a more powerful proxmox custer. I utilize shard storage for all of our vzdump backups. After getting the new cluster up and running...

We do, server going down wasn't the problem, it coming back up after I forgot to put grub back on it was :-). I had just figured that it copied 'everything' not just the ZFS. Lesson learned along with the fact that I should have rebooted anyway just to check! So two lessons learned. Thanks for...

hummmm.......that is a good question. While I have not tried it personally, I would imagine that since you can install from a USB thumb drive and a USB CD/DVD drive that you should be able to install from a USB hard drive. If I were in your position I would throw Parted Magic or Hirens (or...

?? Are you trying to install from a USB CDROM drive or a USB thumb drive? It sounds like you are trying from a CD. As far as installing from a CDROM drive, I have done it in the past so I assume that it should still work. You may want to verify if your system itself supports booting from CD/DVD.

Well as luck would have it, a while back I had to replace one of my RAID1 drives and they are hot-swappable. When I replaced the drive, it resilvered just fine and I went about my business. Fast forward more than a year later (without ever having to reboot the server) and the power goes out and...

So the power company lost a transformer last night and our proxmox server went down after its large UPS died. This morning when trying to bring it back online it fails to boot. Controller sees all drives including the two SSD RAID1 drives that is the boot device. However when booting it gets...

@Nemesiz - Thank You. The is the way it works on other ZFS systems, just wanted to make sure it was the same on Proxmox.
