I have a peculiar case where NAS4Free has corrupted the meta-data on my = 4-disk raidz pool and a few flavours of FreeBSD and a latest version of = OpenIndiana I've tried go down just when I try zpool import with no = additional parameters (kernel panics). I have more or less given up of my precious data, but if any FreeBSD dev = wants to investigate or help me fix the problem I'd gladly try any = special build you'd want me to. PS. I've tried removing disks one by one, but any 3 out of 4 cause = kernel panics and with just two I can't get my data back. PPS. zdb -l works and reports valid information about zpool = configuration, but I can't fix any problems with zdb.
