Hoping that the gods are with me and that you knowledgeable people can assist me with this _really_ big screw up... FreeBSD4.6-stable I was setting up Vinum (rather successfully I might add) until last when I tried to configure a second mirror with two different drives... All I can tell you is this... I had one vinum mirror set-up with this info: drive da3 device /dev/da3s1e drive da4 device /dev/da4s1e volume mirror setupstate plex org concat sd length 0 drive da3 plex org concat sd length 0 drive da4 Working fine. I moved /usr to that mirror and edited /etc/fstab to point /usr to this new mirror -- which worked fine. Then I wanted to set-up another mirror on another two drives, so I (stupidly) changed that vinum.conf to the following: drive da3 device /dev/da3s1e drive da4 device /dev/da4s1e drive da1 device /dev/da1s1e drive da2 device /dev/da2s1e volume mirror setupstate plex org concat sd length 0 drive da3 plex org concat sd length 0 drive da4 volume mirror1 setupstate plex org concat sd length 0 drive da1 plex org concat sd length 0 drive da2 And started vinum and used the create -f command. Then there was an error, something about no space on one of the devices (presumably, the device where the mirror was already working). Next thing I know there's a kernel panic or something that stops the system. If I reboot, the kernel panics with a "fatal trap 12: page fault while in kernel mode" message... Vinum sais that a device is not functioning properly and can't 'sync' the devices... I can't figure a way around this. The /usr (and binaries) are not accessible, neither is my data. I can't start the system. I'm hoping you can help... (Wish I spent the 10 minutes and made that 'one last backup') All I'd like to do is reverse that last vinum configuration... but I can't get to any of the binaries because /usr is offline. I don't mind re-building the system, but I moved my last back-up to that first mirror (which I thought would be safe) and now I don't have access to it. Signed 'having a rough day', phillip.
