    OK, I think my browser cache was outdated. After refreshing the proxmox webui it is available for selection. Then it's time to spin up otel collector and test the monitoring.

    UdoB reacted to wishy's post in the thread [TUTORIAL] FabU: can I use Ceph in a _very_ small cluster? with Like Like.
    Oddly enough, after going down a massive Ceph rabbit hole and getting ever increasing amounts of Ceph+proxmox content pushed to me by "the algorithm", I was reading through the manual before starting the deployment and spotted ZFS replication...

    UdoB reacted to waltar's post in the thread Lenovo SR650 V3 Proxmox Storage slow storage with Like Like.
    The Micron 7450 MAX are tlc with plp which is good. With "ZFSPOOL RAIDZ2" you get in fio just the iops of a single disk, recreate pool as mirror. For ceph you just have a single 25Gb active line for writing default 3 times each block so it's only...

    UdoB reacted to gusto's post in the thread client connection: 127.0.0.1:60994 with Like Like.
    It seems that the problem has been solved. It is unbelievable, but the problem was the UTP cable between the Proxmox server and the router. The original 1.5m patch cable was used between the server and the router. I crimped the RJ45 connectors on...

    Well especially in a "I don't want to take the whole house offline scenario" for a house I think a two-node cluster with ZFS Storage replication is the better approach: If you have a low-power device (like a raspberry pi or a nas) which can act...

    UdoB reacted to MarkusKo's post in the thread Poor GC/Verify performance on PBS with Like Like.
    Thats expected, the more backups you add the slower GC & verify will get due to how PBS handles deduplication (many small chunk files) and hdd's can't handle that well. Solutions would be, switch to all flash storage for your backups or if...

    UdoB reacted to Partake5177's post in the thread VM with win server 2025 showing always high load on disk? with Like Like.
    Solved: I did not create my hard disks on the zfs pool, instead it was running on local-lvm... That is why everything was so slow.

    UdoB reacted to Johannes S's post in the thread OS Inmutable as core of Proxmox. with Like Like.
    It would also make host backups a lot easier because then you would just have to backup the modifiable files (configuration etc). So I see the benefits, but I also see a huge issue: A big benefit of ProxmoxVE is it's flexiblity since it's...

    UdoB replied to the thread Different storage amount shown in GUI and df -h.
    The 152 G is the virtual disk size, given to the virtual guest. The 58 GB is the space of one (or more, you didn't show us the output of df) filesystem(s). Often both are coupled and give similar size - but that is not a must. Examine the...

    UdoB reacted to Skynetter's post in the thread Trycoo/WO-4 miniPC - 2.5GbE NIC, multiple NICs and multiple VLANs with Like Like.
    After a lot of head scratching, I figured out how to get two NICs working on mini-PC. One is a 2.5GbE port, which needs driver update to run at 2.5GbE, and the other is a 1GbE port. The two NICs are on two different VLANs as well. Here's the...

    UdoB reacted to martinkubat's post in the thread Swap space usage with ZFS with Like Like.
    In my humble opinion, what you’re seeing is just normal Linux behavior: it may swap idle pages even with free RAM to keep ARC/cache. Personally I’d suggest trying zram (with zram-tools or systemd-zram-generator) instead of disabling swap — it...
