Hello, I have the same issue - any resolution?

Dear, this command does the same freeze on the host. In the meantime I migrated to LVM/LVM thin with SSD cache on the same hardware and everything works fine for 3 weeks (0 issues). The hardware is following - maybe one other person with the same problem has the same hardware components. It...

Dear, sorry it was not RAIDZ+1 .. this was on the second server on that one it was RAID1. Again, thanks for help, highly appreciated! Just installing with Debian Strech base RAID1 and LVM on and Proxmox per Repository top. I'd like to find out if it works without ZFS on that Hardware.

Hello, got the extrem issue now, after reboot I do not come up because ZFS blocks kernel (120s message) ... ZFS on Proxmox is dead for me .. far too instable for production.

Hello, the mitigation without virtio is only for lower load as above. If the load get's increased it stilll freezes with SATA. See example without gzip ssh root@remoteserver.com "dd if=/dev/vg1/partiton bs=4M | pv -s 1500G | dd of=/dev/sda bs=4M

Seams that there is a mitigation .. when virtio is not activated the diskspeed goes to about 60 % down and it doesn't come to this freeze.

Hello, here ist the way how you get this reproduced: Standard Proxmox ZFS root install on a server from iso (Hetzner EX42, 64 GB RAM, 4 Cores) a) 4TB b) 4TB Enterprise SATA with ZFS RAID Z+1 After install, add 100 GB parttion to read and 100 GB log cache SSD but it happes without this step...

This happend on Archlinux too and the fix was to increase the timer to 1000. What wories me .. the config of Proxmox is 250 .. but when you measure it you get 100 and I don't know why this is. The easiest way would be to make a kernel with 1000 and retry. I have this issue on all my ZFS proxmox...

Dear, this is also on non JBOD. There is an issue with ZFS on Proxmox because this does not happen outside Proxmox. There are several threads with that issue when you have high disk load that the kernel freezes (120s messages). This seams to be an issue caused by the Proxmox kernel (probably...

Hallo, habe das selbe Setup, d.h. vorerst das klappt mal sehr gut, ich schlage dir aber ein abgeändertes Konzept vor. Was du brauchst sind virtuelle Switches (entweder den einfachen Linux Switch oder besser noch den Openvswitch den man auf Proxmox mit apt-get install openvswitch-switch...

Dear, if found some indication that the issue comes from a too low Kernel config_hz parameter in Proxmox (shall be 1000 to prevent this happening but proxmox uses 100/250). Can anyone confirm this?
