Point-and-print Windows driver upload fails with NT_STATUS_NETWORK_BUSY during rename
Last modified: 2023-03-29 15:19:24 CEST
Same situation as Bug #41849 / Ticket#2016072221000163: Windows printer driver upload failed with this error message: "Ein Treiber EPSON Universal Print Driver Typ 3 – Benutzermodus, x64 konnte nicht installiert werden. Das Netzwerk ist ausgelastet." On the print server (Samba/AD DC Master in this case) there are a couple of messages like this in log.smbd: =============================================================== [2016/07/25 15:46:29.811999, 3, pid=22525] ../source3/smbd/open.c:881(open_file) Error opening file x64/E_2VIF0DE.VIF (NT_STATUS_NETWORK_BUSY) (local_flags=2048) (flags=2048) [2016/07/25 15:46:29.812024, 0, pid=22525] ../source3/printing/nt_printing.c:1039(move_driver_file_to_download_area) move_driver_file_to_download_area: Unable to rename [x64/E_2VIF0DE.VIF] to [x64/3/E_2VIF0DE.VIF]: NT_STATUS_NETWORK_BUSY =============================================================== AFAIK this was even after locally working around the issues of Bug #41849. Temporarily disabling oplocks fixed the issue: ucr set samba/oplocks=no; service samba restart Looking at log.smbd I also see some occurrences of the error for GPO files, so there might be some general oplock issue here. Deactivating kernel oplocks alone didn't fix the issue.
Occurred surprisingly in a customer environment after uploading drivers worked like a charm all the time. Switching off 'samba/oplocks=no' followed by a 'service samba force-reload' was able to working around this issue.
