Upgrading from 5.4 -> 6.2 zvol linking fails


Jul 10, 2020
Completed the upgrade from 5.4 to 6.2. After rebooting, attempted to add a new VM. The raw disk image is created successfully, however, the link fails to create:

TASK ERROR: unable to create VM 102 - timeout: no zvol device link for 'vm-102-disk-0' found after 300 sec found.

The contents for the zvol.rules is as follows:
# Persistent links for zvol # persistent disk links: /dev/zvol/dataset_name # also creates compatibility symlink of /dev/dataset_name KERNEL=="zd*" SUBSYSTEM=="block" ACTION=="add|change" PROGRAM="/lib/udev/zvol_id $tempnode" SYMLINK+="zvol/%c %c"

Not sure if there is a missing hook file/action or a file system permissions blocking the creation of the link. Perhaps something else.

I'm at a loss for the next steps in identifying the underlying issue here and looking for guidance to resolve the problem.

What are the steps to troubleshoot and resolve this issue?
