I have a 7502P here, no probs with the CPU so far. Running it on a TYAN platform.

Hi, upon booting the system (only during boot so far), I get a segfault in ZFS: [ 17.905941] ZFS: Loaded module v0.8.3-pve1, ZFS pool version 5000, ZFS filesystem version 5 [...][ 20.804544] zfs[4387]: segfault at 0 ip 00007f565ddde694 sp 00007f5656ff5420 error 4 [ 20.804546] zfs[4379]...

If I read this correctly, it's about scrubbing the pools, i.e. testing data integrity, while the trim is about discarding space on SSDs...

Ok, thanks all. I take from this discussion that there is nothing yet built into pve to execute the trim, and that it's thus ok and maybe even required to, e.g., setup a cron job which regularly executes zpool trim for the SSD pools.

That would also be an option. However, the documentation of ZFS suggests that „zpool trim“ is better performance-wise:

Am I correct in assuming that I will need to create a cron job to run "zpool trim" on, e.g., a weekly basis? Because the "autotrim" property doesn't appear to be set on zpools by default (neither "zfs get all" nor "zdb" show it), and I couldn't find any existing cronjob or timer that runs "zfs...

Ok, thanks. I will fix this from within the VMs then - either with udev rules or with assigning adapter names via netplan, depending on the VMs.

Currently looking to setup Proxmox on a similar system, and am wondering if you‘ve made any progress? I also found these, by the way: https://github.com/openzfs/zfs/issues/8381 https://github.com/openzfs/zfs/pull/10018

Hi, I have a new hardware platform here and am considering to move from an Ubuntu server running kvm/qemu VMs to Proxmox for the new machine. I found the migration doc in the wiki, which is working ok. However, there are a few details that impact the VMs, one of which is that NICs get renamed...
