What does the following error in the NFSSERVER.LOG file indicate?
%NFS-W-CANTCVT, could not convert variable length file -NFS-E-INVFMT, invalid file format or internal error
Certain types of files (object files, database files, etc.) can't be converted due to their make-up or record sizes.
If you have many files of this type it might be useful to export the directory using the /NOCONVERT option.
