I know that one of the ZFS releases had a bug in the free space map. This would also cause panics on OpenSolaris. This problem is apparently recoverable. The above panic references a Solaris panic in sm_space, which could be the space map. See this: http://www.joyeur.com/2008/01/22/bingodisk-and-strongspace-what-happened I'm not clear about which version of ZFS code is in FreeBSD, and whether the free space map bug is present there or not. Does anyone know which ZFS is in FreeBSD? Anyways, if you really need the data, it might be possible to boot the newest version of OpenSolaris, and let it repair your filesystem. Tom
