Unable to copy object (file read failed) on parallel FS

[matzmz]

I am currently working within an HPC environment where we utilize a BeegFS network storage system that is mounted at the /data/ mountpoint. Each node within the system also possesses a local disk formatted with the XFS filesystem.

When I attempt to execute a compression function on directory located on the local disk, the operation completes successfully. However, encountering the same scenario with a directory located in the /data/ directory results in errors (same file copied on /data/, checksum verified). Despite conducting a thorough examination of the BeegFS backend, we have been unable to identify any issues.

Below is the stack trace detailing the error encountered:

ERROR:root:Unable to copy object (file read failed: time = Mon Apr  8 10:28:53 2024

I would greatly appreciate any assistance in understanding and resolving this error.

Thank you.
