Backup from gpcrondump to Netbackup fails with "error while loading shared libraries"


Pivotal Greenplum: 4.3.x

Greenplum Command Center (GPCC): 3.x


When backing up with gpcrondump to Netbackup, it fails with errors in the master.

Error Message

In the .rpt files, we can see the following errors:

 Master (dbid 1) Host mdw Port 5432 Database dbtest BackupFile /data/master/gpseg-1/db_dumps/20170628104103/dbtest_test_gp_dump_-1_1_20170628104103_post_data: Failed with error:

The following can be seen in pg_log on the master:

The variable LD_LIBRARY_PATH might contain out of date lib paths. 

This documentation indicates we should add the following path to the variable LD_LIBRARY_PATH


However, if there is any other path listed before this, it might be causing conflicts if it is pointing to an outdated lib version, for example, /usr/local/greenplum-cc-web/./lib.


A permanent solution would be to upgrade any out of date components that might be causing the issue, in this case, GPCC from 3.0.1 to 3.2.2.

A workaround or a way to test the issue would be to list the conflicting paths at the end of the variable LD_LIBRARY_PATH and restart the database. The backup should succeed.
