    Vielleicht übersehe ich ja etwas, aber „clientlos“ wird es eher nicht gehen, „agentlos“ aber schon. ;-) Warum nicht einfach ein Tool wie Uptime Kuma nutzen? Das Tool kann ICMP-, HTTP- und noch einige andere Checks durchführen und funktioniert...

    Ich in Form von managed und unmanaged Switches ohne Layer3. :D Das reicht mir nämlich hier in meinem Heim-Netzwerk. :) Wenn es dann eher um ein größeres Netzwerk und nicht um "Spielerei" zu Hause gehen sollte, dann könnte man auch sagen/fragen...

    Willst du die Route auf Veränderungen überwachen, oder willst du wissen, ob der Server erreichbar ist? Das ist ein Einzeiler: ~$ export SERVER=irgendeinserver; while true; do echo -n "$(date) "; ping -c 1 -q -W 2 "$SERVER" &>/dev/null &&...

    IsThisThingOn replied to the thread Nonsensical behaviour from zfs.
    Just to be clear, you don't encrypt the source pool and then just pull ZFS snapshots to your encrypted backup pool and want encryption there, right? Because simply encrypting on the source would be easier otherwise. ZFS is a server filesystem...

    If you have configured email notifications, you will get SMART errors. I am not 100% sure if you also get ZFS and scrub errors by default, but I guess that is the case.

    What makes you think, that PBS sending mails to one single e-mail address would trigger an IP block on spamhaus.org? Where? On spamhaus.org? Did you do that?

    ext4 on raid5 on a P420i with 1GB FBWC, which essentially acts as PLP for HDDs, is fine too. The cache is big enough to hold the metadata, and all the atime updates during a GC run will be caught by the cache, and eventually written in bulk.

    raidZ1 is known to not be good for IOPS: https://forum.proxmox.com/threads/fabu-can-i-use-zfs-raidz-for-my-vms.159923/ . And your drives might be consumer drives without =1&c[nodes][0]=16&o=date']PLP. Lots of threads about disappointing (write)...

    IsThisThingOn reacted to andretona's post in the thread [SOLVED] Need help with my ZFS pool with Like Like.
    Thanks everyone for helping me with this problem. I decided to move all data to another pool (no SMR drive) and remove those drives from the server. I will mark this as Solved.

    Just as a bad designed example: one single pool, RaidZ2, three devices for the Special Device because two were not stable - and one being attached by USB. Again: bad design. What I can see here is this: root@pvec:~# zpool iostat -v 5...

    Seems so; it's great that it works fine for you! That's why I very often emphasize "my context"... :-)

    IsThisThingOn replied to the thread [SOLVED] Need help with my ZFS pool.
    Do you expect a connection error and not the probably very old 2TB WD red drive? VRPF failed, right? You pulled it out and inserted the 9TN2, right? BTW don't do that if you have enough bays. Just insert the new drive and let the resilver do...

    PBS does really, really do random writes. It needs IOPS - as many as it can get. For ZFS there is the rising problem of fragmentation of the free space --> it is not guaranteed that a single 2-4 MB chunk can be written sequentially at one...

    IsThisThingOn replied to the thread PBS testimonial (hardware requirements are a joke).
    To be more precise: L2ARC is not optimized for read workloads. It is an added read cache that caches stuff that evicted ARC before. It does only do read cache, never write cache. Not sure if I would agree with that statement. I have not run...

    Of course not :) They are bottom of the barrel trash SSDs! Look at the price. I use it as a boot disk. Which is mirrored with another drive. When using a drive, I suspect a firmware issue leading to total failure and plan my vdevs accordingly...

    run it again but this time with a PBS destination so you get a TLS result on PVE. Then run the same benchmark again on PBS, where you don't get a TLS result.

    IsThisThingOn replied to the thread Confused About my ZFS Storage.
    That is why everybody will recommend you to use mirrors for blockstorage hypervisors and not RAIDZ. RAIDZ can be good for files, but is not good for block storage. Short overview on how this works: 4k secotor size is the default. So you will...
