ZFS special device metadata reserved percent

Aug 31, 2023
Hi all,

After an update and reboot I can no longer boot, with a ZFS kernel module error as shown in the screenshot below. This is due to a line I had in modprobe.d/zfs.conf
"options zfs zfs_special_class_metadata_reserve_pct=10%" - This was working OK until the latest update, now it seems to cause the module to barf.

Does anyone know how I can set the special device metadata reserved percent correctly?

I can get past this by commenting that line out, loading the module and continuing. However I'd like to be able to tune that option again.

Proxmox 8.0.4
Linux 6.2.16-18-pve SMP x86_64
ZFS version 2.1.13-pve1

Kind regards.
