zfs discuss - Jan 2007 - ZFS panics system during boot, after 11/06 upgrade

Hi,

I''m looking for assistance troubleshooting an x86 laptop that I
upgraded
from Solaris 10 6/06 to 11/06 using standard upgrade.

The upgrade went smoothly, but all attempts to boot it since then have 
failed.  Every time, it panics, leaving a partial stack trace on the 
screen for a few seconds.

The stack trace includes:

zfs:vdev_mirror_open+44
zpool:vdev_open+b2
zpool:vdev_vertex_load+b4
zpool:vdev_graph_traverse+25
zpool:vdev_graph_load+2d
zpool:spa_load+57
zpool:spa_open+10f
zpool:spa_directory_next_pool+ca
zpool:spa_open_all_pools+4f
zpool:spa_name_lock+19
zpool:spa_open+7c
zpool:spa_directory_next_pool+ca
zpool:dmu_objset_find+1f4
zvol:zvol_attach+7b
genunix:devi_attach+8f
genunix:attach_node+71
genunix:i_ndi_config_node+ab
genunix:i_ddi_attachchild+41
genunix:devi_attach_node+71
genunix:config_immediate_children+d7
genunix:devi_config_common+66
genunix:mt_config_thread+11a
unix:thread_start+8

I can boot the system into Solaris failsafe mode and mount the root file 
system.
There are ZFS file systems.  There are no zones.

Any help would be greatly appreciated, this is my everyday computer.

Take a look at page 167 of the admin guide:
http://opensolaris.org/os/community/zfs/docs/zfsadmin.pdf

You need to delete /etc/zfs/zpool.cache. And, use 
zpool import to recover.

Cheers,
Jim

Thanks.

In Solaris Failsafe, I have mounted the root of the real OS instance 
onto /a.  There is a /a/etc/zfs directory, but it is empty.  No zpool.cache.

The doc doesn''t describe a solution for that situation.  Any other
ideas?

More diagnostic information:

Before the afore-listed stack dump, the console displays many lines of 
text similar to the following, that scroll by very quickly.  I was only 
able to capture them with the help of a digital camera.

WARNING: kstat_create(''unix'', 0, zio_buf_#####''):
