After upgrading to cxapm 3.0 and running a Vertica backup using the vbr.py utility, we are seeing this warning in the backup log:
2017-02-07 09:00:09 localhost vsql Warning from vsql: WARNING 4156: Node: v_drdata_node0001: Non-existent snapshot 'Backup_Feb-05-2017'. It might be removed already
We need to know what is causing this and if it has an impact on the backup?
This is a known issue with Vertica.
There is an internal defect open and they will fix it in a future build.
This warning can be safely ignored.
It will not impact the process of the backup at all.
