Please show the exact errors you are getting. You should not need a
mon on the same node to create an mds, though you will want an
/etc/ceph/ceph.conf that points to the mons.

scrubbing and deep scrubbing are not completing. There is only 1 client accessing the

I enabled pg_autoscaler and found that it was reducing the number of PGs per OSD from 116
to 104.5 at this time, but it wasn't helping with space consumption equalization. I
found loadbalancer and enabled that and it is in the process of evening out. As we were
also having mds crashes even after increasing mds memory, i tried enabling multimds with
