Aha, wasn't aware of restricted groups. Googled and read the docs, and have now set up a restricted group for just the two main machines, which all the VMs on them will now have their HA set to. For the time being HA is set to "ignore" on all VMs while we're dealing with the errant switch, but...

Thanks for that, clear and concise. Having checked in tank1 and tank2 on the main machines that the disk files were still present, I moved the remaining VMs back to the proper hosts by the following process: 1. In a terminal window on the the "wrong" host: cd /etc/pve/qemu-server; cat xxx.conf...

We have a Proxmox cluster comprising two identical large machines, with 120 cores and 370+ gig of memory, and with each machine having two ZFS disk pools, Tank1 of 50TB HDD, and Tank2 of 2TB of SSD, and a third less powerful machine with just one ZFS pool, a mirrored paid of 10TB disks...

Odd issue came up today, shutting down one machine in a 3-node, 4-vote cluster caused both other nodes to unexpectedly reboot. We have a cluster consisting of two identical high capacity Supermicro servers running Proxmox 7, one less powerful Dell blade server running Proxmox 6.2 (planned to...

Thank you for detailed answer, and yes, I can see the symlinks when I look in /dev/tank1 The reason I was looking for the files was that while upgrading node-2 (of a 3-node cluster) from 6 to 7, node-3 suddenly fenced (for reasons we're still not sure of) and one if it's VMs then appeared to...

I have a Proxmox cluster, running V7 and V6 versions (am upgrading one machine at a time). On all the machines, regardless of version, the VM data disk files do not show up at all using the normal Linux file commands like ls and df. Is this expected behaviour or do we have a weird fault...

That makes sense, detach so spare takes over fully, swap drives, re-add new as new spare. In this case no cables, 16 drive backplane, so that should be OK. I'll bring the replaced drives back and bench-test them on a different system. Thanks for reply, was getting hopelessly confused by...

I have a pool, configured as a raidz-1, of 5 SSD drives plus 2 spares, and in the most recent scrub, two of the main pool SSDs have been marked FAULTED. The spares have automatically taken over so at the moment the pool still has full redundancy, and I want to replace the faulty drives...

Watching this as very interested in the answer. I'm thinking of deploying a system that will have 3 SATA slots, plus an internal NVME in a PCIe adaptor card, plan is that SATA 1 will be an SSD as the Proxmox / boot disk, SATA 2 and 3 will be large HDDs as a ZFS mirror plus the NVME (partioned...

Thanks! This section resolved the issue: Enable Nested Hardware-assisted Virtualization. Much appreciated!

We have an existing cluster of VMware ESXi and XenServer 6 and 7 hypervisors, running multiple Lunix and Windows VMs of various vintages. We plan to migrate all the VMs to Proxmox on new hardware, using ZFS replication to give us failover and HA. For the more modern Linux VMs this seems...
