IIsThisThingOn 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...

IIsThisThingOn replied to the thread 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...

IIsThisThingOn replied to the thread 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.

IIsThisThingOn replied to the thread slow sync job PBS.What are your results from this: https://pve.proxmox.com/wiki/PBS_Client_CPU_Benchmark ?

IIsThisThingOn 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...

IIsThisThingOn replied to the thread PBS testimonial (hardware requirements are a joke).btw, we already have 2026 ;)

IIsThisThingOn replied to the thread 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...

IIsThisThingOn replied to the thread 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.

IIsThisThingOn reacted to Johannes S's post in the thread Yet another "ZFS on HW-RAID" Thread (with benchmarks) with
Like.
In regard to the discussion: I remember that @Falk R. mentioned several times in the German forum that using ZFS on HW RAID is ok if (and only if): You know what you are doing (which imho doesn't hold true for people calling others "dogmatic"... -
IIsThisThingOn reacted to UdoB's post in the thread Yet another "ZFS on HW-RAID" Thread (with benchmarks) with Like.
The point is: you can not know that. Of course you are free to use any available technology you want - and a lot of installations are using hardware Raid (edit: ... without a checksumming filesystem). No fight here; if it works for you/them...

IIsThisThingOn replied to the thread 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...

IIsThisThingOn reacted to NickyDoes's post in the thread Backup tool for standalone ZFS datasets to Proxmox Backup Server with Like.
I've already written what it does, and am not about to go on the full defensive. Reiterating succinctly: This is a wrapper for PBC. It adds inheritable backup config from within the dataset properties (vs. remembering to modify your PBC scripts)...

IIsThisThingOn replied to the thread PBS parallel backups & PBS performance.ups, you are totally right, you can only run one backup at a time.

IIsThisThingOn replied to the thread PBS testimonial (hardware requirements are a joke).since I got asked about my PBS from @news, here are some more detailed informations:

IIsThisThingOn replied to the thread 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...
-
IIsThisThingOn replied to the thread 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...
-
IIsThisThingOn replied to the thread PBS parallel backups & PBS performance.What speeds do you expect? I think that 3GB/s per second is already pretty fast. What is your target speed you aim at? Is the current speed a problem? Or are you just surprised that you can't reach line speed and suspect an issue with your setup...

IIsThisThingOn replied to the thread Empfehlung für einen Neuling - Sicherung ein ca. 20 TB VM eines PVE auf einem PBS und anschließend auf Band.Nur weil etwas möglich ist, ist es noch lange nicht sinvoll. Aber ja, Server2 könnte mit HDD passtrough als VM laufen, sowie auch PBS3 eine VM sein könnte und auch Server4. Nur warum? Und warum all die negativen Konsequenzen in Kauf nehmen? Und...
-
IThat's mainly for legal reasons so not comparable. Also zfs isn't just a one-man-show and has multiple comanies funding development and is mature enough not to loose data. In contrast bcachefs developer Kent Overstreet wanted to violate kernel...
-
IAnd this is unlikely to change since the main developer of bcachefs has shown that he isn't able to conform to the kernel developers workflow: https://www.phoronix.com/news/Bcachefs-Removed-Linux-6.18 This is imho a large red flag why I...
