Thanks for you assistance! I liked the first suggestion, but i didn't want to involve a working system. So i bought 2 new nvme drives. I will keep the old ones as spare.

You have any suggestions how to continue from here? Kind regards.

And indeed, on system 1 both eui64 fields are the same, on system 2 they are not. What i'm not sure, if these are generated by the system, or they are defined by the nvme's themselve?

Yes, i do have that message. And since 2 days i'm running kernel 5.15 again. What i'm trying to understand, is why can the other identical system (same hardware & software) run the kernel 6.2 without problems (and this error message), while the first one can not 6.12 without problems. The one...

Hi, Thanks. I did notice that info too. But i'm asking myself why would it be only a problem on 1 of 2 identical systems... i wouldn't mind to much reinstalling, if it could make sense/help. Kind regards.

Hy all, I have 2 identical systems, both have 2x CT500P2SSD8 nvme's in zfs config (mirror) for booting and storage of vm's and lxc's. They all have the same firmware (P2CR012). They both have the same motherboard (x470d4u), processor and memory. After opt-in to 6.2 kernel on both systems, one...

I had once similar strange issues, turned out to be my power supply, more specific, too many drives connected to the same power line.

I created other zfs filesystems in the shell, they all appear in the UI. After all, i think the UI does the same when making zfs filesystems.

Hy, I have trouble with the following usb zwave stick (passtrough to lxc container with domoticz): 10c4:ea60 Cygnal Integrated Products, Inc. CP2102/CP2109 UART Bridge Controller [CP210x family] I've searched the forum (and google) and followed what other people did before, and added this to my...

Well before this all worked. When i try it now i get: Fetched in submodule path 'submodules/ubuntu-disco', but it did not contain fdc10a3711d4cb8ae2c42efb2c89dcca919d1e4d. Direct fetching of that commit failed. Makefile:120: recipe for target 'submodule' failed

Thanks for the good explanation!

Update: the cksum errors started appearing on another pool, only 3. I decided to power the server directly from the ups, and rewired inside the server the power lines from the psu to the disks. It appeared all the disks were on 1 line of the psu. So i divided them equally over the available...

Thanks for the update. I tested with 3 machines, didn't work. After i rebooted the switch, all fine now! I still do no understand the difference in concept between hooking up proxmox to the bond or the vmbr, can someone explain? Thanks for the help!

True, i forgot about that... So i added another connection from another machine. The sum of the connections never go above the capacity of 1 interface?

Thanks for the hint. Unfortunately, that didn't make any difference. Any other hints? What is the difference in hooking up proxmox IP to the vmbr vs the bond?

Hy, On 2 proxmox servers, I bonded 2 network ports (2x1gbps) with lacp, created it in the switch, and created a vmbr on top of it. Both servers are connected to the same switch, I expected a speed increase but it still looks limited to 1gbps when doing transfers between them (fe zfs...

Lucky or thunder before the storm ;-) I think i'll replace my psu. Cabling should be replaced too i suppose. If it continues i'll swap the controller and pool to another system. Then i will suspect the mobo/ram. I saw in the logs one trace of read/write errors on all drives, just for a brief...

Thanks all for the replies. After i did a 'zpool clear' a scrub was started. After it finished, the errors were still there and the pool still in a degraded state. The scrub had repaired 11G. Since i rebooted allready several times before the 'zpool clear' command, and i had tried to re-attach...

Hy, One of my pools (not a boot pool) is in a degraded state because one the drives has 'too many errors', 39 cksum mentoned, 0 write 0 read. I checked the drive with smart values show nothing. I did a zpool clear, and is now resilvering, and has 155 cksum allready. Any ideas? Thanks in advance...

Thanks, i suspected allready that more zfs pools would have consequences on the ARC cache. Would a separate ssd for cache (l2) and log be beneficial then? A single ssd with ext4 for booting proxmox only seems the alternative, but you sacrifice redundancy on the booting device then. Not a perfect...
