Hi, I created a new ceph cluster, and create a pool, but see "stuck
unclean since forever" errors happen(as the following), can help point
out the possible reasons for this? thanks.

With three OSDs and a single host you need to change the crush ruleset
for the pool, since it tries to distribute the data across 3 different
_host_ by default.
