I tried importing with debugging enabled, but dmesg output was the same as in my previous message. I had so much faith in raidz + snapshots, that I have absolutely no backups of this system :( I don't care about time which is needed to find a problem and possible fix, but I am really worried about my data now. What else could I do? And yes, I know that I shouldn't treat CURRENT as a stable and reliable system, and you never have too much backups. I just didn't realized how important data on this machine is until I realized that maybe I just lost it... Crap. -- Bartosz Stec
