[SOLVED] kernel panic while scrubbing pool on zfs

Hi all,
I have been having some issue with kernel 4.1 and zfs 0.6.4.2. using losetup with files on a zfs filesystem kernel oops and hang the computer. I planned to tough this one as I don't need that much to map files to loop devices.
However, I just had two kernel panic, during a long scrub of a pool. The scrub was about 50 percent and I am kind of tired here. I will be skipping this 4.1 kernel version and running on the good old 4.0.7, or maybe check if lts is manageable without too much hassle.

This is topic is a question and warning - have you had kernel panic on scrub - is this only my hardware affected by something else. if this is generic - well, you have been warned.

Scrub (on a rather small pool) worked fine here. Maybe you can join the mailinglist and throw your remark/question on there (if not done already) together with some more information about your particular configuration. This might be an issue with your particular configuration and it's better to have it fixed than to stick on 4.0.7 for maybe a long time.

No panics during scrubs of a 2 TB pool here.

Re: [SOLVED] kernel panic while scrubbing pool on zfs

Thanks all,
it appears I'm the only one with issue. This looks to be my hardware that have stability issue on that new kernel.
I have marked the thread as solved.
