Description Ram Raja 2019-09-23 07:13:02 UTC

Description of problem:
After creating a FS subvolume, fetching its path hangs.

How reproducible: Always

Steps to Reproduce:
```
   $ ceph fs subvolume create vol00 subvol00
   $ ceph fs subvolume getpath vol00 subvol00
```
Actual results:
The second command just hangs and ceph-mgr daemon hits 100% CPU utilization

Expected results:
The `fs getpath` command should return the path of the FS subvolume and ceph-mgr shouldn't utilize 100% CPU.
