If its one drive that causes such issues, maybe you get lucky and zfs pauses the pool with an warning, or you get a read error or sth. The thing is, it makes absolutely sense that it is utterly slow as shit, but it shouldn't lockup for hours, thats not normal. On another side, i readed that...

yeah i seen that on another thread already, i think its exactly how you say, someone forgot to update the meta. but if you install proxmox-headers-6.8 before dkms, will it still try to install pve-headers 6.1? however, for the issue itself, you can remove the 6.1 headers afterwards i think, or...

From earlier research, most drives either die early, or don't die, because they were replaced already. There is no rule that says that the drives will die after 5 or 10 years of usage, just indicators that out of 5k disks of the same model, most are diying in the first 6 months, or start diying...

The 990 Pro's Firmware updates don't help, they help only Samsung for Marketing reasons... 970 and 980 are somewhat okay, but 990 Pro is pure crap, no firmware will fix that crap xD And yeah i will replace them at some point, just that HDD-Z2 Pool is just a movie storage pool that is anyway not...

I can only say, it would be insanely amazing, to get 6.9. I myself would take advantage of the preferred core support with amd-pstate driver. That amd-pstate driver driven my genoa-Servers with performance+performance down to 140W Consumption for 90% of the time and 700W during load scenarios...

Actually thats not completely true with the smallest disk in the pool. On Raid 10, zfs can grow to the size of one mirror, here is an example: capacity operations bandwidth pool alloc...

6 Pairs of mirrors, will give you a huge speed increase in iops and speed itself + no parity calculation. But at a huge cost of total available size. I googled "rebalance zfs" and there was a script called inplace rebalance something on github. Maybe you could do that. With my "you will run...

I edited it for zfs defaults, 64k+128k, should be more appropriate for everyone that uses the default recordsize of zfs. But you can compare both scripts, to see what i changed etc, to modify yourself... Cheers

Yeah, your pool is hugely unbalanced. The first z2 stripe is full, 92,3% usage. The other one is almost empty compared to that xD That comes in my opinion only from one thing, your drives. It looks to me like the Hard-Drives in the first Stripe (the one that is full) are a lot faster. That...

Sorry, i was initially mad that no one tryed to help, so i didn't wanted to post a solution. But that doesn't make sense, to get an a.... just because no one has a clue. However, the solution is somewhat simple and not so simple. The main issue is how the CPU-Cores are Accesing the Cache...

Ah and you're right about the 75%, after 70% the zpools get usually utterly slow. After 90% the zpools are almost not working anymore. But you made a lot of free space again as far i understood, so let's see simply your output and what can help based on that

can you post the output of "zpool iostat -vy POOLNAME 1 1", just to see if its probably unbalanced. "zpool list -v POOLNAME" to check fragmentation. "zfs get all POOLNAME" for additional information. That should be enough for the first part. PS: If you delete 5TB of data and move VM's around...

That are indeed backups.... And you have a Backup Storage definition and im sure to this folder. You can delete that backups if you don't need them or do whatever you want with them. Or you can delete them in the GUI too... Datacenter View.... Omg you are so blind xD In your own picture the...

you're right not much, other as guaranteed ecc. But my ecc on my 5800x home-server works without issues either. Maybe ecc will get disabled with bios updates in future for ryzen, who knows...

no, i think because the kernel and headers of proxmox have simply a different name. However, if you install dkms, simply install proxmox-headers either. It will stay there forever and update automatically, like leesteken already said. I dont see a downside.

- ls -lah /backup/dump/* - You dont need a Cluster, just Check the Storage category und the Cluster View (The Cluster View is the first item in the GUI, above your Server) - If you're sure that there can't be anything, you can remove that folder, but check first what there is in it.

Passthrough with amd onboard gpu's doesn't work. You can use it only in LXC Containers, for Plex for example. PS: I would build a Home-Server based on the new AMD 4004 Series. Thats a relative Cheap Plattform with 28 Lanes. Everything else has only 16/20/24 Lanes, and above that are only...

check whats in there. check your storage configuration in procmox cluster section, that directory must be used somewhere there, or check your crontab. But in "dump" folders are usually Backups, i think images too, but unsure.

But what does this have todo with Proxmox?

What means lost networking in GUI, which GUI?
