EON Mode - Adding Nodes Error (Directory already exists)
I'm testing eon mode on version 11.0.0-3.
I'm adding and removing the same 2 AWS nodes to primary subcluster. Basically, i'm going from a single node to a 3 node and back down to 1 node (k-safe 0). When nodes 002 and 003 are not in the db i stop them in AWS to save $$. I get this error sometimes when i try to add the 002 and 003 nodes back in.
Failed to prepare a host for database participation. See /opt/vertica/log/adminTools.log for details. Host hints follow. 10.20.xx.xx directory already exists: [Details - <ATResult> status=Error host=10.20.xx.xx error_type=<class 'vertica.engine.api.errors.ATDBPrepareError'> error_message=Catalog parent directory already exists: (/vertica/data/demo1_04)]
I want to force recreate the directory if possible so i don't have to go to each of the two new nodes and delete the directory. This is for scripting purposes for auto scaling i'm working on.
I'm using this admin tools method
adminTools -t db_add_node -s 10.20.xx.xx,10.20.xx.xx -d demo1_04 -p 'pass'
When i look at the options i don't see a way to force recreate the directory. Here are the options i see
[dbadmin@ad2-demo1-04-node0001 root]$ admintools -t db_add_node -help Usage: db_add_node [options] Options: -h, --help show this help message and exit -d DB, --database=DB Name of the database -s HOSTS, --hosts=HOSTS Comma separated list of hosts to add to database -p DBPASSWORD, --password=DBPASSWORD Database password in single quotes -a AHOSTS, --add=AHOSTS Comma separated list of hosts to add to database -c SCNAME, --subcluster=SCNAME Name of subcluster for the new node --timeout=NONINTERACTIVE_TIMEOUT set a timeout (in seconds) to wait for actions to complete ('never') will wait forever (implicitly sets -i) -i, --noprompts do not stop and wait for user input(default false). Setting this implies a timeout of 20 min. --compat21 (deprecated) Use Vertica 2.1 method using node names instead of hostnames
Am i missing something? Do i need to fully remove the two nodes from the cluster so vertica drops the directory before i try to add them to db again? I want to be able to add and remove the same nodes from the db as smoothly as possible. This is the only error i'm running into right now.
