Quoting Larry Rosenman <ler@lerctr.= org> (from Thu, 24 Feb 2022 20:19:45 -0600):

I tried a scrub -- it panic'd on a fatal double fault. 

Suggestions?

The safest / cleanest (but not fastest) is data export and pool re-creat= ion. If you export dataset by dataset (instead of recursively all), you can= even see which dataset is causing the issue. In case this per dataset expo= rt narrows down the issue and it is a dataset you don't care about (as in: = 1) no issue to recreate from scratch or 2) there is a backup available) you= could delete this (or each such) dataset and re-create it in-place (=3D no= t re-creating the entire pool).

Bye,
Alexander.
