That is correct. On Prod we do have 22TB and on DR we

But did you check that you really have missing files/data? Just to
make sure it is not just some issue with how data is stored/counted in
different clusters.
Assuming you did and data is missing, then the only way to proceed I
think is to issue resync, running on the secondary site:
rbd mirror image resync cifs/research_data
Note, it would mean recreating the image and resyncing all 22TB
though.
And it would be nice to add some monitoring to be able to detect the
moment if the issue happens again, and report it to the tracker
attaching the rbd-mirror logs.
