You can try the path of a file based on gfid (method 2) via:
https://docs.gluster.org/en/latest/Troubleshooting/gfid-to-path/
The gfids from the strace should be there, but if the file was renamed/deleted - it is normall to be missing.
Have you joined the last gluster meeting to discuss the problem ?
Best Regards,
Strahil Nikolov
