Subject Re: Can't Add AWS Node due to /mnt/cassandra/data directory
Date Thu, 28 Aug 2014 04:14:23 GMT
Make sure you have also setup the ephemeral drives as a raid device (use mdadm) and mounted
it under /mnt/cassandra otherwise your data dir is the os partition which is usually very
small.

However in non OpsCenter installs you would have to create the data directories first:

Things look good for 3 or 4 green circles, until I either get this error: Start Errored: Timed
out waiting for Cassandra to start. or this error: Agent Connection Errored: Timed out waiting
for agent to connect.
