Hello,
We have an issue on one of our clusters. One node with 9 OSD was down
for more than 12 hours. During that time cluster recovered without
problems. When host back to the cluster we got two PGs in incomplete
state. We decided to mark OSDs on this host as out but the two PGs are
still in incomplete state. Trying to query those pg hangs forever. We
were alredy trying restarting OSDs. Is there any way to solve this issue
without loosing data? Any help appreciate :)

Directory for PG 3.1683 is present on OSD 166 and containes ~8GB.
We didn't try setting min_size to 1 yet (we treat is as a last resort).
