Which volmode is in use for vmpool/os5 ('zfs get volmode vmpool/os5')?

I don't know what patritioning scheme pfsens uses, but 'gpart show
/dev/zvol/vmpool/os5' would be of interest.

You need volmode "geom" and something like /dev/zvol/vmpool/os5p2 or
/dev/zvol/vmpool/os5a for your mount special I guess.
