I counted only four instances of "NO VINO", which I take to mean that the old devices (da4s1, da4s2, da5s1, and da5s2) were all relatively clean, while the new devices were all corrupt. > I've just checked the source code, and it looks as if I don't log > whether the configuration updates are enabled at all.

No, everything seemed to work just fine -- vinum showed the sub disks, plexes, and volumes as being up, I could create filesystems, etc.... > Anyway, the good news is that the data is almost certainly still > there.

Well, we've already deleted and re-created the devices once, and now we can't even get vinum to start because it can't read the supposedly existing devices. I am at a loss to understand how we would recreate the devices another time, on top of the old configurations (and hopefully be able to retain all the data, etc...). Is there something I'm missing? Maybe you could explain this process in a little more detail? -- These are my opinions -- not to be taken as official Skynet policy ====================================================================== Brad Knowles, <blk@skynet.be> || Belgacom Skynet SA/NV Systems Architect, Mail/News/FTP/Proxy Admin || Rue Colonel Bourg, 124 Phone/Fax: +32-2-706.13.11/12.49 || B-1140 Brussels http://www.skynet.be || Belgium "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.
