NDMP backups stopped working with error code 164

Question

I have had two NDMP backups running from an NS-480 for several months. All of a sudden, one of the backups has started erroring out. The last part of the log is: 2011-06-14 20:02:00 avndmp Info <9510>: Opening file history '/usr/local/avamar/var/judicial/filehist_pipe_17623' as pipe 2011-06-14 20:02:04 avndmp Info <9544>: Starting data transfer 2011-06-14 20:02:04 avndmp Info <0000>: NDMP Info: SnapSure file system creation succeeds 2011-06-14 20:04:47 avndmp Error <0000>: Lost pipe to avtar: Broken pipe 2011-06-14 20:04:47 avndmp Info <6651>: Process 18144 (/usr/local/avamar/bin/avtar) finished (code 164: Internal failure) 2011-06-14 20:04:47 avndmp Warning <6653>: CTL workorder 'Weekday-Normal-1308096000121#0' non-zero exit status 'code 164: Internal failure' 2011-06-14 20:04:56 avndmp Error <9571>: Premature end of child 2011-06-14 20:04:56 avndmp Error <9562>: Backup for target /Judicial/ had errors. 2011-06-14 20:04:56 avndmp Info <9563>: Closing NDMP session. 2011-06-14 20:04:56 avndmp Error <9469>: Snapup of /Judicial/ aborted due to 'Error during NDMP session'. 2011-06-14 20:04:56 avndmp Info <9471>: NDMP session result: avtar returned:157 'Miscellaneous error' ndmp returned:157 'Miscellaneous error' 2011-06-14 20:04:56 avndmp Info <7232>: Final summary generated subwork 1, cancelled/aborted 1, snapview 0, exitcode 157 -------------------------------------------------------------------------------------------------------- ----- END avndmp log 2011-06-14 20:05:01 EDT (1 warning, 4 errors, 0 fatal errors) -------------------------------------------------------------------------------------------------------- Any ideas of what is wrong and what to do to correct the issues? The other NDMP on the same NS-480 is running with no errors. Accelerator is running 5.0.106-28.

I found this in one of the other log files:

2011-06-16 16:40:30 avtar Error <5775>: Internal Error: backtree: bad response cbba528385a6a1b338c0eecc22603556180ca7e3 72654 ADD_HASH_DATA=2 serial=72654 seq=0 flags=R:N:0 kind=9 rsp=MSG_ERR_INVALID_PARAMETERS

Does that entry help?

Apparently, a bad cache file.  Deleting the p_cache file allowed the backup to complete OK.

Hi David, I'm running into the same problem. Was that in /usr/local/avamar/var/ on the NDMP node? Thanks, Michael

DavidLJennings · Answer

Yes, /usr/local/avamar/var/name_of_ndmp_instance/ where the name is the name you used when you set up the ndmp client.

Murrieta · Answer

Okay, thanks. Looks like that fixed my NDMP backups from a Celerra too.
