NDMP backup aborted "connection closed/aborted without CLOSE command"
Applies to
- ONTAP 9
- NDMP
Issue
- The backup job at the DMA seems hung and/or DMA suspends the backup.
- Upon enabling the NDMP debug logging (SVM-scoped NDMP / node-scoped NDMP) and inspecting the logs, below errors are seen:
backup.log
"Error (Message from Write Dirnet: Interrupted system call)"
"Error (DUMP IS ABORTED)"
ndmpd.log
"DEBUG: BUF_Stream::input: fd=13 read -1 [EOF or error]: Connection reset by peer (ndmp_io_process)"
"DEBUG: connection closed/aborted without CLOSE command from [DMA_IP_address].port"
This indicates that the DMA (backup application) didn't send "NDMP4_DATA_ABORT" NDMP message to abort the backup.
