    [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 its job. AFAIK ZFS can still make use of you...

    Not what I am seeing in the real world. Let's start with a fresh VM where nothing is already backed up: zpool iostat poolBackup 1 capacity operations bandwidth pool alloc free read write read write ---------- ----- ----- ----- ----- ----- -----...

    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 extensive tests to proofe it, so take this with a...

    PBS testimonial (hardware requirements are a joke)

    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. That is why I would never use two identical drives...

    slow sync job PBS

    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.

    What are your results from this: https://pve.proxmox.com/wiki/PBS_Client_CPU_Benchmark ?

    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 save 4k sectors onto your drives. Imagine a 2GB iso...

    PBS parallel backups & PBS performance

    PBS is a rather poor technology for file backups. If you don't need blockstorage but files, something like robocopy, rsycn, zfs send or the likes will perform miles better, because it only has to read metadata (and for ZFS not even that). PBS on the other hand reas ALL the data, EVERY single...

    PBS testimonial (hardware requirements are a joke)

    Jesus, these prices are insane. Anyway, the PSU was used (Privatanbieter means private seller) and you don't need a CPU cooler (AMD has one included), nor a case fan.

    PBS parallel backups & PBS performance

    I don't think is does 4k r/w and even on my consumer hardware I linked to you in another post I can easely reach 100MB/s. Anyway, in the real world, PBS will be way less relevant, since you only need to send changes. So in your case the local SHA256 we bill the biggest limitation. To go back...

    PBS parallel backups & PBS performance

    ups, you are totally right, you can only run one backup at a time.

    PBS parallel backups & PBS performance

    AFIK you can easely test this. Just start two backups at the same time. Then run it again. Now it should be 100% dublicates and you are only benchmarking SHA256 That is exactly my guess. 3,6GBit/s is pretty far away from your goal of 10GBit/s. Alternatively, you could get a faster setup by...

    PBS parallel backups & PBS performance

    Second test was on the PBS. Not sure if I can follow. I would even argue that the culprit is both CPUs. The first clear bottleneck seems to be TLS. I gave you 4 parts of TLS. We can rule out 1. According to you, we can also rule out 2. For 3, you get 203MB/s. That is IMHO a clear bottleneck...
