Hi Weiwen,

Thanks for the reference link.  That does indeed indicate the opposite.  I'm not sure why our issues became much less when the big files were deleted.  I suppose it's just that there was more space available after deleting the big files.

Is a file in ceph assigned to a specific PG?  In my case it seems like a file that's close to the size of a single OSD gets moved from one OSD to the next filling it up and domino-ing around the cluster filling up OSDs.

I believe no. Each large file is split into multiple objects, 4MB each by default. These objects are evenly assigned to all PGs in the pool.
