---------------------------------------
Summary: Review disk failure modes if permissions are in the way
Key: CASSANDRA-8126
URL: https://issues.apache.org/jira/browse/CASSANDRA-8126
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jeremy Hanna
Our disk failure modes are great in most circumstances, but there are a couple
where they may not make sense.
Take the example of trying to snapshot your data on a node. If permissions
aren't set up properly, the snapshot may fail which triggers a disk failure
which brings down the server.
On the other hand, if you're trying to truncate a table, it may make sense to
bring down the node if it's unable to snapshot because it's unable to properly
make a hardlink backup of the data that's getting deleted - which is the
expectation. This may be debatable.
Perhaps in certain cases we can simply throw obvious errors and not bring down
the server. In other cases, we should be clear about why we are bringing down
the server - perhaps for specific cases like the second case, having a special
output to indicate why it's going down. I say special output because it's not
obvious why truncate to bring down any nodes in their cluster.
