    Proxmox 7>8 upgrade in a cluster.

    Might be worth adding a step to enable maintenance mode https://pve.proxmox.com/wiki/High_Availability#_node_maintenance to the instructions. I forgot to do this and had one of the nodes get fenced mid-upgrade which caused some "fun" which then required me to use the OOB to get it back online...

    listing images failed: (2) No such file or directory (500) on EC pool

    Proxmox 7.3-6, Ui Displays : Gui shows listing images failed: (2) No such file or directory (500) on EC pool when trying to list images on an EC pool I suspect it's trying to List the EC pool instead of the corresponding metadata pool This works on a new install that's still on 7.3-3

    Proxmox 7.3-3 Firewall Weridness?

    Just installed Proxmox 7.3-3 on 3 nodes (Haven't updated yet as hopefully we're subscribing to the enterprise repo) CEPH 17.2 across 3 nodes connected by 2x10G LACP Was getting a lot of the following messages in the CEPH logs 2023-03-09T10:50:39.317446+0000 mon.localhost (mon.0) 70 : cluster...

    Ceph replicas 1

    For anyone who doesn't care about dataloss and loves to live on the edge. In the example below the pool is called "danger" ceph config set global mon_allow_pool_size_one true ceph osd pool set data_pool min_size 1 ceph osd pool set danger min_size 1 ceph osd pool set danger size 1...

    P and E cores?

    Has anyone tried running Proxmox on a 12th/13th gen Intel cpu with both P and E cores? I'm guessing as these are more consumer CPU's perhaps not, but I was tempted to build something for the "homeserver". At the moment I have a cluster of very slow low power i3's to test CEPH on but I could...

    Kubernetes storage?

    Just wondering what people are doing for kubernetes PV's when running K8s/K3s in VM's on-top of a proxmox cluster. I was thinking of exposing PVE-CEPH to rook as an external cluster and doing it that way , but I'm not sure if that's likely to bite me later or if it will cause issues with...

    Datacenter firewall rules not applied to VM > Host traffic?

    So I have a Proxmox machine in a co-lo with a public range on vmbr0 (It's a single server co-lo so I don't have a router/firewall I control upstream) It's firewalled using the PVE firewall, configured under the datacenter tab and I've confirmed I cannot access the Proxmox UI.etc from an...

    Ceph Single Node?

    Would I be crazy to run Ceph on a single node? configured for OSD level redundancy (instead of host level). Was thinking of using Ceph as I can change the resiliency settings, or replace disks with larger ones and re-balance easier than if it was just a static ZFS. (This is assuming I can put...

    Ceph command to enable trim.

    can also be set per OSD Supposedly shouldn't be needed with modern enterprise drives Absolutely needed with crappy consumer drives like the ones found in my homelab ;-)

    LAB: Ceph EC

    So I'm playing around with Ceph in a lab setup on some extremely low-end hardware, and I was testing EC on a 3 node cluster. I had Proxmox installed on USB sticks as originally, I didn't realise the OSD can be a partition rather than the whole disk. I started removing/replacing OSD's so I...

    Socket Count?

    For the Paid subscriptions how does the Socket count work, If I had some machines that have a 2S motherboard but only one CPU installed (I.e the 2nd socket is empty) Do I need to license them as 2S systems?

    Local disk vs CEPH for clustered applications?

    Wanted to get the community's opinion on local (non-redundant) storage for clustered applications. Essentially what I'm thinking of doing is Raid1/ZFS mirrored SSD for Proxmox itself. CEPH for VM general disks But then I'm wondering for applications where the application is clustered and...

    Proxmox in Azure?

    Has anyone had any luck getting proxmox to run in Azure, as some of the machine types support nested VT. I tried to install it on bullseye but it got as far as installing ifupdown and then dropped the VM off the network. I was hoping to setup a Lab cluster on Azure for playing with Pve-Ceph

    Windows backup?!

    Whilst you'll be missing features like shadow copy and I'm not sure if permissions will be preserved it looks like the Proxmox backup client can run in a WSL2 environment and furthermore it appears at least that providing the Linux user can read them it can backup files from the windows side as...

    Community Pricing

    Not really one for here, but as there isn't anywhere else more appropriate that I can find... Is there any scope to review the community pricing, only because these days 2 Socket servers are pretty cheap on the second hand market, but even with 2S you might have less total cores than a modern...

    Legacy ubuntu VM killed by backup?

    Any ideas for this one, Essentially I have a VM where doing a backup snapshot kills it. PVE 6.1.5, When doing a snapshot backup of a legacy ubuntu 14.04 VM to a NFS share provided by a centos8 VM onto a VDO volume backed by an ISCSI mount on an RS814 (The Centos VM doing VDO is excluded from...

    Ubuntu 18.04 LXC container wrong gateway.

    I have a Ubuntu 18.04 LXC container running on Proxmox 5.3-11 that likes to pickup the wrong gateway, essentially the container won't be able to access the internet and I'll find it's default route is pointing at 10.xxx.xxx.254 instead of 10.xxx.xxx.1 However in the networking config for the...

    Backing up a UnprivilegedLXC?

    Need some recommendations for backing up an Unprivileged LXC container that's on an Iscsi LVM and managed by HA manager to an target that's an NFS share. Snapshot fails because of permissions issues, Stop doesn't want to work either because vzdump won't auto stop a VM managed by HA. The common...

    2 node cluster?

    If I have 2 proxmox servers on the same network but one is AMD and the other is INTEL can I still cluster them? Not interested in HA but it would be nice to be able to manage them both from the same WebUI session.

    5.0-15 > 5.0-18 worrying message

    Now to me trying to delete /usr/local or /usr/local/share seems like a really bad idea!
