Hi, I did few more test runs and it seems that it happens during this sequence 1.populate data using dd 2. delete away ALL the shard files in one of the brick .shard folder 3. Trying to access using dd, no error reported 4. umount and mount. 5. Trying to access using dd, no error reported 6. umount and mount. 7. Trying to access using dd and Input/Output error reported during step 3 and 4, no file is created under the .shard directory For step 7, a shard file is created with same file name but different gfid compare to other good replicas. Below is the client log and brick log with more details in the attached log.
