    I am not convinced! 4 binary TB (correct: 4 TiB) is 4398046511104 Bytes. And it is 4294967296 KILOBytes. The last one is possibly used to show wrongly 4.2 TB...

    Perhaps a maximum filesize limit is hit somewhere? Compare: https://en.wikipedia.org/wiki/Comparison_of_file_systems#Limits

    That's surprising and not expected, of course. How did you create that pool? What gives "zpool status" before reboot and "zpool import" after it? We are talking "write cache", right? It tells ZFS that data has been written to disk while it...

    UdoB reacted to IsThisThingOn's post in the thread NAS UGreen DXP4800 Plus with Like Like.
    Ist generell auch bei nicht so wichtigen Diensten eigentlich immer eine gute Sache. Hilft auch enorm beim troubleshooten. Der ganz grosse Vorteil von LXC ist die Nutzung von files anstelle von blockstorage. Das ist eine kompliziertes Thema und...

    UdoB reacted to cwt's post in the thread Best practice: How many apps per LXC/VM? with Like Like.
    For LXC I would only run one application to keep it small and isolated as much as possible. As @UdoB mentioned: you can keep this set-up also with VMs. I personally don’t run a VM for only one docker container. One exception are really mission...

    UdoB reacted to trollbot's post in the thread Best practice: How many apps per LXC/VM? with Like Like.
    Thank you both for your replies. So it looks like "pick your poison", based on hardware and requirements is the way to go and there is no "one size fits all". Which is totally OK for me, as I can then decide on a case-by-case basis what makes...

    This heavily depends on your applications, usecases and used Hardware. For example running docker inside lxcs us known to break from time to time ( e.g. after updates) so any docker application should be run in a vm. But if you have limited RAM...

    For me? Any device with PLP. Via a German search engine: https:// geizhals.de/?cat=hdssd&xf=7156_Power-Loss Protection~7525_SATA Most of my SSDs are "Enterprise class". Most of my NVMe are not. This make no sense, necessarily. But especially...

    UdoB replied to the thread Question on PBS setup and hardware.
    Both (!) is suboptimal. (You know that, right?) But if I am forced to choose: the PBS (or any backup system) should be independent from the source it will backup. You'll probably want the backup to be available and usable when (not: if!) the...

    UdoB reacted to aaron's post in the thread Help to setup cluster with Like Like.
    A node on which the cluster is initially created can have guests. Any node that is joining the cluster needs to be empty. Therefore create the cluster on the node with the PCI passthrough TrueNAS VM. The other node needs to be freed. Either by...

    You will get different (but valid!) answers to this question. But my decision is: one service == one VM! This especially means that I do separate docker containers in a single VM each. Yes, this seems to waste resources. But I like it this way...

    UdoB reacted to leesteken's post in the thread Entire cluster rebooted with Like Like.
    Sounds like every node lost quorum (with HA enabled) at the same time. This suggest a network hick-up of some kind, which appears to have been temporary. Check the system logs of the nodes (just before the reboot) and your switches.
  • UdoB
    Probably: yes! But please: PVE is meant to be the basis of a multitude of VMs. Put it on a stable hardware and avoid each and every "ideas" possible on this lowest level. Please! This means PVE "owns" the hardware! No dual-boot whatever OS you...
  • UdoB
    Ideal? No! Acceptable? Maybe! It always depends on your expectations! I have some nodes (in a cluster) which boots from a single device. (Because of the restrictions of a Mini-PC in a $Homelab.) But the hosted VMs live on a redundant one...
  • UdoB
    You list only a single pool named "special" consisting of a single (triple!) mirrored vdev! There is no "Special Device" involved! Not sure what you want to achieve and what to recommend... sorry.
  • UdoB
    Thanks, I will start with PBS installing on the Intel NUC with 8gb ram and 110gb ssd after that is working i'll come back to you to explain me please how to setup the 2nd machine as cascade.
  • UdoB
    You say "3" but you list five. If you can actually run more than three then I would evaluate Ceph. With only three I would use ZFS with replication. Most of the drives are HDDs, right? In that case I would highly recommend multiple ZFS mirrors...
  • UdoB
    My PBS's use surprisingly low CPU resources. The limits come from the storage system. Usually. I would opt for the low power device to run 24*7 and cascade the other one, as mentioned. I am not sure if I understand that correctly...

    "The only usecase for any backup server is to restore data when (not: if) the source system fails." Another usecase is restoring a file when the source system is OK and someone needs the file which has been deleted or modified in the meantime :).

    UdoB reacted to DerekG's post in the thread Temperature with Like Like.
    I suggest once again that people evaluate the Pulse monitoring app, which uses the Proxmox api to monitor not only the temps, but the CPU/RAM/Disk/Backups/hosts/docker apps etc. on a single pane of glass, right across your estate. They have made...
