Full cluster is 14.2.8.

I had some OSD drop overnight which results now in 4 inactive PGs.  The pools 
had three participant (2 ssd, 1 sas) OSDs.  In each pool at least 1 ssd and 1 
sas OSD is working without issue.  I’ve ‘ceph pg repair <pg>’ but it doesn’t 
seem to make any changes.

PG_AVAILABILITY Reduced data availability: 4 pgs inactive, 4 pgs incomplete
    pg 10.2e is incomplete, acting [59,67]
    pg 10.c3 is incomplete, acting [62,105]
    pg 10.f3 is incomplete, acting [62,59]
    pg 10.1d5 is incomplete, acting [87,106]

Using `ceph pg <pg> query` I can see the OSD in each case of the ones which 
failed.  Respectively they are:
    pg 10.2e participants: 59, 68, 77, 143
    pg 10.c3 participants: 60, 62, 85, 102, 105, 106
    pg 10.f3 participants: 59, 64, 75, 107
    pg 10.1d5 participants: 64, 77, 87, 106

The OSDs which are now down/out and have been removed from the crush map and 
removed the auth are:
    62, 64, 68

Of course I have lots of reports of slow OSDs now from OSDs worried about the 
inactive PGs.

How do I properly kick these PGs to have them drop their usage of the OSDs 
which no longer exist?

Thanks for you thoughts on this,

peter
