So I have been running Neveda 85 for a while now with ZFS. Recently my machine crashed (I think with drive hardware error). My grub install got corrupted so I went ahead and intalled Neveda 90. Everything was fine and my zpool came back up until the 3rd reboot. Now bootup hangs on the ZFS volumes.I can attach any other SATA drive to the system and it starts fine. But when I attache one of those 4, it hangs. How do I get more info about what is going on? Should I try the Kernel Debugger? Which forum should I post to? -- This messages posted from opensolaris.org
