We did compare and it was missing lot of data.
I'll issue resync and report back.
Thanks,

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.
