Description

It is not only scrubbing what needs to be allowed: - up and down conversion of RAID1 - lvconvert --repair ... Especially repair is critical for users of writeback cache. As a side note: these operations works fine for _corig. Fix pushed upstream as 22a6b0e40b302b333f9bd995c0b81b0146e8232a. Still unable to scrub in .112-1, unless I'm doing it wrong.

This works for me as well now that I also upgraded kernels (to 3.10.0-200.el7.bz1159001v2.x86_64). Scrubbing doesn't work on cache pools that have not yet been used with a cache origin device since they apparently can't be activated. Is this expected behavior?
