The OS is on a UFS filesystem and (it's a mail server) the business part of the operation is on ZFS. One day it crashed with an odd kernel panic. I assumed it was a memory issue so I had more RAM installed. I tried to get a PAE kernel working to use this extra ram but it was crashing every few hours. Suspecting a hardware issue all the hardware was replaced. I had some difficulty trying to figure out how to mount my old ZFS partition but eventually did so. zpool import shows this: pool: email id: 10433152746165646153 state: ONLINE status: The pool was last accessed by another system. action: The pool can be imported using its name or numeric identifier and the '-f' flag. see: http://www.sun.com/msg/ZFS-8000-EY config: email ONLINE ada1s1g ONLINE zpool import -f -R /altroot 10433152746165646153 olddata panics the kernel. Similar panic as seen in all the other kernel versions. http://forums.freebsd.org/attachment.php?attachmentid=1545&stc=1&d=1336261809 Shows a typical kernel panic. http://forums.freebsd.org/showthread.php?t=31820 Gives a bit more info about things I've tried. Whatever it is seems to affect a wide variety of kernels. Any ideas?
