proxmox-file-restore unexpected EOF

[Stefan Radman]

Hi

I have a problem extracting two specific directories from a PBS backup of a CentOS-7 VM.

The original directory is part of an XFS filesystem mounted from an LVM logical volume.

While the PBS journal shows “TASK OK”, proxmox-file-restore reports a short file in the directory and an “unexpected EOF” on the pxar archive.
Extracting the same directory from the PVE GUI leads to an apparently truncated ZIP file without any error message.

Total size of the original directory is 1-2GB and this happens will several of them (but not all of them).

Extracting single files works. Extracting a 3GB directory from a Windows machine in the same backup works as well.
The backup is verified.

proxmox-backup: 2.2-1 (running kernel: 5.15.60-2-pve)
proxmox-backup-server: 2.2.7-1 (running version: 2.2.7)

Does anyone have a hint for me where to look further?

Thanks

Stefan
