I doubt you are really interested in learning it :) But feel free to open up another thread and ask, why "ZFS ate" two of your disks. Post your exact setup and config and the nice people here in the forum will tell you why.

Also not 100% sure about that one. The write buffer is in RAM, but I guess that it will be counted as ARC. So for example, if you have 1GB in zfs_dirty_data, Proxmox would show 1GB more ARC usage. It is a little bit a chicken & egg discussion. I could argue that if the capcitors break down, you...

Sorry, my bad. I meant you misunderstood how SLOG works. The fact that you bring in UPS into this discussion is another evidence of that.

This tutorial might leave out some details, and in parts be written a little bit sloppy. Sorry if you don't like that writing style, sorry. If you have suggestions on how to edit it to make it better, feel free to add stuff. There seems to be a lot of misunderstandings, when it comes to ZIL...

I for one learned that ZIL can be on svdev, thanks to @Johannes S :)

I am honestly a little bit suprised on how much false infromation we have in this thread. There seems to be a lot of misunderstandings, when it comes to ZIL. SLOG is just an external device instead of the pool for ZIL. async without SLOG: A async write, goes into ARC (which is in RAM) into TXGs...

Probably you set up something wrong. I don't know how to say it in English without sounding like a dick, but the fact that you used a SN700 as SLOG tells me that you misunderstood ZFS.

that isn't true.

I did never said it was wrong. I did not even watch the vid. I only said your statment is wrong. Which it is. Is is a terrible idea, that is why nobody sane would recommend that. No. You are again making implications that are not true. You imply for example with your broad generalisation...

sorry, steh grad auf dem Schlauch. Du hast schon firmware usw installiert und dadurch drehten die Lüfter mit massiv weniger %? Und die minimum fan speed in ILO gesetzt? Ich frage so doof, weil vor der MCP oder firmware installation (ist zu lange her, kann mich nicht mehr erinnern), liefen...

hatte das gleiche Problem mit einem DL20. Lösung war damals sources hinzuzufügen. Nur leider gibt es da ein Problem. Proxmox Debian basiert auf Version trixie und supported wird gen10 nur bis bookworm. Jedenfalls als ich das letzt mal geschaut habe. Da es bei mir aktuell läuft, habe ich...

That is again a broad statement, that is simply wrong. Yes changes are CoW. Yes there is ZIL for sync writes. Yes there is a 16k blocksize. Which has nothing to do with ZFS. A ext4 hardware RAID mirror behaves exactly the same (well besides for rebuilds) SATA instead of NVME would bring me no...

You guys keep repeating that claim, but that does not make it any more true. And it isn't a source. My hypervisor with many Linux VMs, that have wastful docker applications inside, and my other Proxmox Server with many Windows Hosts, both suffer less writes than my MacBook Air that I use to...

It causes more wear when you do a snyc write and when you change a file, yes. Source? You mention pveproxy, but that does not cause siginificant writes. Either way, both isn't really worth mentioning in normal conditions. We should wait for OP to answer the open questions.

First of all, 6% isn't that bad, is it? For half a year. That would mean that it runs for over 8 years. That is pretty good. Longer than warranty. What drive do you use? Consumer or prosumer drives or maybe even QLC? Tell us the drive model. No. ZFS does not by design cause more wear than...
