ReplicatedPG::do_op already does the right thing as far as blocking ops which may flush. What remains is to avoid flushing objects with blocked obcs.

#20 Updated by Samuel Just over 6 years ago

Urgh, non-blocking flushes do not cause scrub to pause. I think the simplest solution is to fail a non-blocking scrub in try_flush_mark_clean if the object is being scrubbed.

#26 Updated by Samuel Just about 6 years ago

Irek, you are seeing the previous incarnation of this bug. The relevant fix has not yet been backported to firefly.

#27 Updated by Samuel Just about 6 years ago

This most recent incarnation is due to oi digests: we block_writes until the end of COMPARE_MAPS. The assert should not fire if !block_writes. Previously, we would always change scrubber.start to be the same as scrubber.end as we changed block_writes.

#28 Updated by Samuel Just about 6 years ago

Making patch.

Also, this is an entirely distinct bug, so I'm making this Pending Backport again and opening a new one.
