How do I determine the primary osd?

You might also first try
ceph osd down 1701
This marks the OSD down in the map, it doesn’t restart anything, but it does serve in some cases to goose progress. The OSD will quickly mark itself back up.
Where 1701 is the ID of said primary.
ceph health detail
is one way that you might see the acting sets of involved PGs, the primary will be the first ID in each’s list. Chances are that you’ll see a common OSD in the sets.

One think I can think of is that these 113 PGs may have a common misbehaving OSD (primary or not) with a ridiculous osd_mclock_max_capacity_iops_ssd value set.
Restarting the primary and/or adjusting osd_mclock_max_capacity_iops_ssd value(s) could help in this situation.
