I was able to start MDS 13.2.1 when I had imported journal, ran recover_dentries, reset journal, reset session table, and did ceph fs reset. However, I got about 1000 errors in log like bad backtrace, loaded dup inode, etc. and it eventually failed on assert(stray_in->inode.nlink >= 1) right after becoming 'active'. I'm doing scan_links to give it another try.
