I am trying to bring in my zpool from build 121 into build 134 and every time I do a zpool import the system crashes. I have read other posts for this and have tried setting zfs_recover = 1 and aok = 1 in /etc/system I have used mdb to verify that they are in the kernel but the system still crashes as soon as import is called. On this system I can rebuild the entire pool from scratch but my next system is 4Tbytes and I don''t have space on any other system to store that much data. Anyone have a way to import and upgrade a older pool to a newer OS? TIA mic -- This message posted from opensolaris.org
