I have a file server VM with about 7 luns attached to it. 2 of them are 2TB. I know the drive is almost full and needs to be expanded. I am now not sure which lun on the host is equivalent to the uuid on the guest. From the host, they look identical. Is there a way to pull the uuid or...

One of my promxox 8.3 hosts got updates and rebooted and never woke up (2 other servers, one which is identical hardware, came up fine). The dell bios on the R720 shows this: This system has it's root as a btrfs mirror on 2 drives, and should be efi. I think I need to boot the installation...

I'm troubleshooting random host reboots which have been causing me huge headaches. I see them in the logs, and nothing appears to precede them. Mar 17 17:06:28 sr66-prox-03 pveproxy[348253]: Clearing outdated entries from certificate cache Mar 17 17:07:10 sr66-prox-03 snmpd[4026]...

I am having an issue where I have 3 hypervisors in a cluster, one is substantially different than the others (totally different CPU generation). Eventually I will replace them all, but that takes time. Until then, I have the CPU type set to the lowest compatible version, and for the most part...

I have a VM in a hardlocked condition. This VM had 2 disks on NAS storage, and was set to migrate in HA. As a short term fix, I moved one of those 2 disks to the local ZFS storage on the node, but I did NOT configure a replication job (oversight). A power event caused the node to drop, and...

I have a 3-node cluster, and had a random reboot today. I went back in syslog, and the reboot was logged, but I wasn't sure if this was a logged event BEFORE the reboot, or AFTER. I want to figure out why this is happening so I can stop it. I think this is the second random reboot this week...

I'm modernizing my environment and replacing some pretty old R710's with Intel(R) Xeon(R) X5687 CPU's with R6525's AMD EPYC 7252 CPU's. My VM's have all been set with the CPU type x86-64-v2-AES (v2 being the highest level my old Westmere CPUs support). When I live migrate between the old and...

I am wondering if I'm doing something wrong here. I have 2 Proxmox 8.2.2 hosts, and they are connected to a TrueNAS Scale which is presenting ZFS over iSCSI LUNS over fiber, everything works well. I have Ubuntu 22.04.04 VM's, with qemu-guest-agent installed, everything seems happy, until I...

I'm a homelab Proxmox user. I have 2 physical servers with Proxmox on them, each with 2 physical sockets. I'm not using a subscription, but that's fine, I don't need the enterprise repository, I don't need the support.... ...Except for the nag. The nag is super effective, I feel bad. I want...

I recently set up ZFS over Iscsi on my truenas using a new 10G fiber network. While setting it up I had a few failures (binding the iscsi to the right nics on the TrueNAS, etc). The result was I tried to move a disk, but the move failed with an error. it's all since been resolved. In doing...

I had an install of proxmox 7 that heavily utilized open-vswitch. Upon upgrade to proxmox 8, I lost networking in the middle of the install as I believe openvswitch was being upgraded. I was able to get in via the idrac console, and the system is up and survives a reboot, but my networking is...

I am setting up a 2-node proxmox cluster. These are connected to my switch via a 4-port LACP bond carrying multiple vlans each of which have a /16 subnet. Vlan 2 (subnet 10.2.0.0/16) is routable and is my management network, I can get to the web interfaces on this vlan and all is well. I have...

I'm using a completely up to date proxmox install and monitoring my Ubuntu VM's using an up to date zabbix. I have noticed a large discrepancy in the memory usage reported in proxmox vs. the memory usage reported by the vm. This makes sense; from the hypervisor side, this is a ballooning...

I found a lot of searching and testing with people struggling on this, but I was able to make this work. I wanted to document my exact steps in the hope it helps someone else. I have a VM povisioned, working, with snapshots and migrations. First, on TrueNAS Scale, I have a ZFS dataset with a...

I'm installing PVE 7.2-1 on a Dell Poweredge R710 from a USB key. I'm attempting to set up a BTRFS RAID1 on 2 drives as the OS, and I have 6 other drives which will be a RAIDZ-2. When attempting to install, I get the following error: "FATAL ERROR:writer: failed to read/uncompress file...

I'm a bit overwhelmed setting up the shared storage for a new Proxmox Cluster in my lab. This is our previous generation hardware which was sitting idle, and each of 10 servers has 4 ~300GB SAS disks. It is connected to our production Dell SAN, where our first testing 2TB lun is presented over...

I have a question about how storage works on Proxmox, and I'm not sure if I've set up my storage incorrectly. I am coming from an ESXi environment where there are compute-only migrations and am looking to emulate that behavior in Proxmox. I have 8 hosts, each with a fiber nic connected to a...

We've created a cluster on PVE 7.0-11 and am attempting to join other nodes. The network is up and the hosts can ping each other by hostname. I can run "systemctl status corosync" and get the following output: root@PROX-02:~# systemctl status corosync ● corosync.service - Corosync Cluster...

We have Proxmox on our previous-generation hardware, as a secondary environment to our newer VMWare environment. Our production Compellent SAN has the following topology: 2 Controllers Each controller has 2 ports One port on each controller is going to a non-routable 10.1.19 subnet, the other...

We are trying to get open vswitch working on 10 hosts running Proxmox 6.1-3. We think we have a configuration that should work, but it doesn't and we can't ping the gateway. These are hosts with 4 nics, we want to bond them with LACP then establish a bridge where we can have virtual NICs on...
