Symptoms

Device file permissions/ownership has been manually set for a raw zvol on the underlying /devices file.

For example:

# ls -ltr /dev/zvol/rdsk/test_pool

lrwxrwxrwx   1 root     root           0 Jan 29 11:45 testvol -> ../../../..//devices/pseudo/zfs@0:28,raw
# ls -ltr /devices/pseudo/zfs@0:28,raw
crw-rw----   1 db      dba     287, 28 Jan 29 11:47 /devices/pseudo/zfs@0:28,raw

Upon reboot the device ownership is reset to the default of root:root
