zfs discuss - Jul 2007 - Any fix for zpool import kernel panic (reboot loop)?

My system (a laptop with ZFS root and boot, SNV 64A) on which I was trying
Opensolaris now has the zpool-related kernel panic reboot loop.

Booting into failsafe mode or another solaris installation and attempting:

''zpool import -F rootpool'' results in a kernel panic and
reboot.

A search shows this type of kernel panic has been discussed on this forum over
the last year. Apparently zfs panicking on a failed write to a non-redundant
pool is a known issue to be addressed (although I''m not sure if the
panic I''m seeing is due to a failed write).

Does anyone know about progress on this issue? I feel this should have more
prominence on the ZFS pages as a known bug. (Looks like apple made a good call
in only going with read-only Zfs for leopard, it''s very very promising
but not yet ready for prime time).

Hi Rodney,

I have been using zfs root/boot for few months without any problem. I 
can also import the pool from other environment.

Do you have problem importing the zfs boot pool only ? or you can''s use
the zfs boot at all ?

Rgds,
Andre W.

Hi,
your pool could be corrupted.
It was created with SNV_64?
Can you post the kernel panic you are getting?

I have a zfs pool on (on a T2000) that "zpool import" (with or without
a pool name) will cause a "dangling dbufs" panic on S10u3, S10u4beta,
and Nevada b61ish.  Prior to booting from my jumpstart server and
disabling zpool.cache, the machine was stuck in a panic loop.  A
support call is open and it is a known problem that (I''m told) is
being worked on.

I only mention this to say that this type of problem is not restricted
to zfs boot.
