limit this find to only those
PGs in question, which from what you have described is only 1. So figure
out which OSDs are active for the PG, and run the find in the subdir for
the placement group on one of those. It should run really fast unless you
have tons of tiny objects in the PG.

ceph tell bench and also via some mixed IO fio runs on the OSD partition
while the OSD it hosted was offline.

o dig
into deeper and stick with the simpler configuration of just using the NVMe
drives for OSD journaling and leave the XFS journals on the partition.

Further clarification, 12:1 with SATA spinners as the OSD data drives.

Are there any safety/consistency or other reasons we wouldn't want to try
using an external XFS log device for our OSDs? I realize if that device
fails the filesystem is pretty much lost, but beyond that?
