Issue

  • XCP copy or resume existing job fails with catalog errors when attempting to create or access certain files in the catalog directory. The following errors are observed in XCP logs:

ERROR: Error creating index: nfs3CREATE 'abc.done' in '10.x.x.x:/catalog/catalog/indexes/abc': nfs3error13: permission denied
ERROR: Error reading command metadata 'abc.json' in catalog id '10.x.x.x:/catalog/catalog/indexes/abc': 'NoneType' object has no attribute 'read'

  • Packet traces and debug logs show repeated NFS V3 CREATE calls for files with extensions .missing, which result in NFS3ERR_ACCES (access denied) or nfs3error13: permission denied.
  • XCP Debug logs:
