    UdoB replied to the thread [SOLVED] QDevice Deployment.
    I believe this is a myth :-) Let's take a look. I've added a QDev to a four node virtual test-cluster. Normal operation: ~# pvecm status Cluster information ------------------- Name: pn2 Config Version: 5 Transport: knet...

    The SLOG will only help with SYNC writes. As far as I know PBS .chunks are written "normal". (Can someone prove me wrong?) And that SLOG will accept incoming data of one single 5 seconds interval while a second TXG (transaction group) is being...

    Running in VM will work, but on the Host itself will see conflicts and complications.

    There are also now Proxmox Partners who offer PBS as a managed cloud service, e.G. tuxis.nl in the netherlands or Inett in Germany. I would expect that other partners (like the ones in North America) would offer something similiar. Their pricing...

    I'm not sure what this is. Maybe RaidZ3? You may show zpool status to show topology information. (Preferable in text form and in ...-tags.) RaidZ/Z2/Z3 can be tricky and may seem to waste a large amount of space. Example...

    There are too many options without additional information. Feel free to add some more technical details regarding your system. (Cluster? Server hardware? Mini-PC? Amount of Ram? ECC Ram? HDD? SSD? ZFS? Number of VMs? PCI-passthrough? ... ... ...

    UdoB reacted to Johannes S's post in the thread Wie viel RAM für Proxmox ZFS RAID with Like Like.
    Wofür willst du denn die HDDs verwenden? Als Datengrab (auch für VMs und lxcs)? Dann ist RAIDZ ok. Wenn du dagegen VMs (also deren Betriebssystem und Serverdienste) darüber laufen willst, solltest du dir das noch mal überlegen, RAIDZ ist schon...

    UdoB reacted to news's post in the thread Wie viel RAM für Proxmox ZFS RAID with Like Like.
    Und bei der Schätzung des Speicherbedarf auch an 2 GByte für Proxmox VE selbst denken. Ich setze rund 1 GByte Ram für 1TB an Datenspeicher an. Mehr geht immer. Und je nach Speichertyp bitte ein zfs quota von ca. 80 % auf den gesamten Pool...

    Ja, bei weitem. https://pve.proxmox.com/wiki/ZFS_on_Linux#sysadmin_zfs_limit_memory_usage : " ... will be set to 10 % of the installed physical memory," - also vielleicht etwas über 3 GiB.

    UdoB reacted to Johannes S's post in the thread Zfs replication and databases with Like Like.
    I wouldn't trust any production data on something, some guy on youtube claimed to work. I also wouldn't trust anything somebody on a forum said who doesn't have his own experience but just repeat something from youtube. I wasn't talking about...

    UdoB reacted to Chris's post in the thread Proxmox Backup Server 4.0 released! with Like Like.
    Hi! What exact error message do you get for the failed backups? Anything of interest in the PVE task log or the corresponding PBS backup task log? We discovered an issue leading to possible deadlocks. A fix is work in progress, please subscribe...

    Did you consider to setup replication/clustering on the database Level?

    UdoB reacted to Johannes S's post in the thread Poor GC/Verify performance on PBS with Like Like.
    An import consideration is the needed capacity ( rule of thumb is 0.02-0.03 of HDD storage capacity ) and amount of ssds since the redundant of the special device should match the redundancy of the pool: See also...

    Also sicherlich ist das Feature noch nicht aktiv. # zpool version zfs-2.3.4-pve1 zfs-kmod-2.3.4-pve1 zpool upgrade Test es halt mal mit raw-Dateiein, anstatt einem realen zfs pool. # man fallocate fallocate -l 1G dev0.raw fallocate -l 1G...

    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.

    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...

    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...
