I'm having a similar difficulty to this thread that I'm hoping someone can help me with. I have a cluster of Dell servers, each with 512G ram, and they are not stressed (screenshot at bottom). Each has a 1G NIC for corosync, and a 10G each for Image traffic (VLAN 101) and 10G for VM traffic...

I see on the roadmap that improvements are planned for larger installations, and was curious if this was (or could be) included in the coming updates? I find that if I'm going to take a host down for maintenance I sometimes want to move several guest VMs at the same time, and would like to be...

I am having a dependency issue. The following packages have unmet dependencies: python3-cephfs : Depends: python3-ceph-argparse (= 15.2.14-pve1) but it is not installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution). root@svr-00:~# apt install...

So, it looks like PBS is not an add-on like the email gateway, correct? So, if I want to run PBS as a VM, do I buy only 1 core, or the number of cores I plan to allocate to the VM?

I tried to add a 5th node to my cluster, and it appears in the running cluster but as offline. I see the correct corosync config on the cluster, but when I look at the new node it did not get an updated corosyn.conf file (in /etc/pve, it did in /etc/corosync), and it will not let me login to...

I'm getting some odd slowness in one member of my cluster. When the backup runs it shows about 3/3MB backup speed (even though iperf3 to the FreeNAS NFS store is 9GB/s) but after migrating to another cluster member it's much faster. Backup from below is on NODE2 (svr-02), slowness is on NODE1...

I'm seeing a very odd and difficult to troubleshoot disk share performance issue in case anyone has thoughts. I have a 4 node PVE cluster, server by a few nodes of FreeNAS with NFS shares. One of the FreeNAS boxes is new, with SSD storage, and as part of bringing it online, I have rearranged...

Hello, I really need some help. I have a 4 node cluster, and I was trying to add redudant ring addresses to the cluster and blew it up. I tried to follow this guide, I did copy and backup the configuraiton. I made a mistake, and now when I try to edit the Corosync file I get a permissions...

I'm realizing that I don't know enough about Linux networking as I need to, and try as I might I can't seem to gleen what I need to know from searches. Here's a picture of what I'm trying to accomplish. I think this is the actual issue that I started working in this post. 192.168.100.0/24...

I'm looking to improve my backup (well, and overall VM, but that's a story for another day) speed in PVE. I've looked around, and haven't found anything on optimization, or even what normal or 'good' performance would be. I have 4 nodes, all on PVE6.1-7, all 12th gen Dell R620/R720 machines...

I backup my guests regularly, but after my little glitch this week, I was wondering (and I've searched) - is there any way to backup the host/node configuration?

I need some help pretty badly. I was following along with this excellent write-up to create a second network for my corosyncing, and I thought it was going pretty well, but now I have all 4 of my nodes completely isolated somehow. I've attached the old and new corosync.conf files, and I've...

So, I've read this thread, and the multicast notes and I'm still seeing occasional retransmits. I have a 4 node cluster, all on the same VLAN (and they are the only machines on this VLAN). They all have 10G copper ports onto the sam Ubiquiti USW-XG-16 switch, connected to USG-XG 10G router...

So, admittedly, my linux skills are not awesome, but I have been using Proxmox with a FreeNAS storage for awhile now, and I want to use one of my large NFS shares that has been working great for backups for VM images as well as I have one large (NextCloud) VM that I have been using local host...

I have a couple of nodes (PVE5.2-1) that have 10G cards in them, and the switch indicates they're bonded at 10G speed, but the pve nodes show 1000bps connections. Do I need to install a driver or set a speed on the interface to get it utilize the port properly? Also, once I get the node to...

I am getting periodic VM lockups, and when I reboot I get an initramfs error. I have no idea why this is happening, and I can rollback to the most recent snapshot, but I worry that eventually it's going to bite me.

I have read through the wiki (here), but I'm confused still on the right process for my case. I have an Ubuntu 16.04 VM that I have fully configured but it is running out of space. I extened the disk size in the GUI, which now shows the size as 7TB (SCSI sda on the local node) , and I see the...

Hello, I'm a very new Proxmox user, and I have done a fair amount of searching, so please bear with me. My Node3 has 2 internal storage pools, a 1G SSD and a 13TB RAID. The RAID is not showing up in the GUI as storage. I have followed the steps outlined in this nice video...

So, complete Proxmox noob here. I have been reading about Proxmos, iSCSI, mulitpathing, etc. and I'm not clear on the benefits for my case. I'm setting up 2 (for now, I will probably set these up with mirror/redundant pairs) a R620 and R720, both with dual 10G NICs. I'm also configuring a...
