Can you please open a new thread for that, the current one is rather for io_uring and an bug we actually could manage to reproduce after a lot of testing and also fixed together with upstream kernel devs.

pvesr itself does not uses io_uring at all currently, so this seems rather unrelated to this thread and possibly an issue with ZFS on your system.

Would be also great if you could add some details about the system (CPU/motherboard) and the ZFS setup in the new thread, thanks!

@t.lamprecht , as I understood the bug is fixed, right? In which kernel version the fix was implemented?
Yes, the io_uring related one, which this thread was initially about, is fixed. See:
FYI, there's a newer kernel as package pve-kernel-5.11.22-3-pve version 5.11.22-6 which solves an issue with some unexpected EAGAIN's that the io_uring kernel code got from some subsystems softirq code paths.

Hi all for me it's not resolve. Got again 2/3 days crash since kernel update.
Going to try to mount a stack trace listener to post it here.

It ends up with a new SSD for rpool/boot.
The old one (new from 12/2020) show smart error at boot and only allow me 2 backups before definitely dying.
