Vinum is a Logical Volume Manager that was introduced in FreeBSD 3.0, and for FreeBSD 5 was ported to geom(4) as gvinum. gvinum has had no specific development at least as far back as 2010 and it is not clear how well it works today. There are open PRs with reports of panics upon removing disks, etc. And, it also imposes an ongoing cost as it must be updated when other work is done (such as the recent MAXPHYS work). I suspect that by now all users have migrated to either graid(8) or ZFS. I plan to add a deprecation notice after a short discussion period, assuming no reasonable justification is made to retain it. The notice would suggest graid and ZFS as alternatives, and would be merged in advance of FreeBSD 13.1. Then, gvinum would be removed in advance of FreeBSD 14.0. Please follow up if you have experience or input on vinum in FreeBSD, including past use but especially if you are still using it today and expect to continue doing so.
