That is true. IMHO it should be removed from RELENG_5 and _6 if it isn't already. > and that gvinum/geom_vinum is not ready for production use. Well the only reason it might not be is that it hasn't seen widespread testing, as far as I can tell it should all just work. I do use gvinum on a 5-STABLE host and it has worked well for me in the past [1]. > As it seems to me, this means that anyone using > 4.11 (say) and vinum will have to abandon vinum (i.e. quit doing software > RAID) in order to upgrade to 5.4. 5.4 does have alternatives to vinum (which is another reason why gvinum hasn't received as much testing): gmirror, graid3, gstripe, gconcat. > That can be both laborious and slow > (e.g. if you have /usr on, say, a four-drive vinum volume in 4.11, you're > going to have to replace those drives with something else in order to go > to 5.4.

As far as I can tell, it should just work. To pick up the latest round of vinum fixes it might be best to run 5-STABLE (ie. RELENG_5) but it should not be necessary unless you run into difficulties. But the only way to know for sure if things work, is to test... --Stijn [1] for some reason I discovered a configuration problem earlier this week, but the other part of the mirror is holding up and it seems that I can reconstruct the broken part this weekend. If anything, it seems that a gvinum mirrored plex is robust. -- "Coca-Cola is solely responsible for ensuring that people - too stupid to know not to tip half-ton machines on themselves - are safe.
