First of all, do not rush into bad decisions.
Production is down and you wanna make it online but you should fix the
problem and be sure first. If a second crash occurs in a healing state
you will lose metadata.
You don't need to debug first!
You didn't mention your cluster status and we don't know what you have.
We need some information;
1- ceph -s
2- ceph health detail
3- ceph df
4- tail /var/log/ceph/ceph-osd{crashed osd number}.log -n 1000
