Technical troubleshooting and more

While trying to start one of Vertica nodes you may face a data consistency problem. from vertica.log <PANIC> @v_vdb_node0005: VX001/2973: Data consistency problems found; startup aborted         HINT:  Check that all file systems are properly mounted.  Also, the --force option can be used to delete corrupted data and recover from the cluster         LOCATION:  mainEntryPoint, /scratch_a/release/svrtar5575/vbuild/vertica/Basics/vertica.cpp:1613 so.. don't PANIC :-) solution: restart the problematic node with force flag which will repair the corruptions from buddy nodes.  [dbadmin ]$ /opt/vertica/bin/admintools -t restart_node -d $db_name -s $host --force and the result: *** Restarting nodes for database vdb ***         restart host node0005 with catalog v_vdb_node0005_catalog         issuing multi-node restart         Starting nodes:                 v_vdb_node0005 (node0005)         Starting Vertica on all nodes.
