Hi, After I analyzed the metadata of this case couple months ago, I find out that there is another possible bug which might trigger this assertion fail in shift(). I had posted a patch two months ago on the list to explain and fix this issue. Could you help reviewing this? https://www.redhat.com/archives/dm-devel/2015-August/msg00155.html Thanks, Dennis 2015-10-20 0:02 GMT+08:00 Mike Snitzer <snitzer@xxxxxxxxxx>: > On Mon, Oct 19 2015 at 6:45am -0400, > Nikolay Borisov <n.borisov@xxxxxxxxxxxxxx> wrote: > >> >> >> On 10/19/2015 01:30 PM, Joe Thornber wrote: >> > On Mon, Oct 19, 2015 at 12:16:53PM +0300, Nikolay Borisov wrote: >> >> [Resending as I had typo in the dm-devel's mailing list the first time] >> >> >> >> Hello, >> >> >> >> Using kernel 3.12.47 I've hit the aforementioned issue.
