If you have advice that is not covered here, consider adding it!

Debugging on a Live System

The following provides instructions for connecting to a CRDB shell on a running system.

Find the zone running CockroachDB. This can be accomplished by running zoneadm list -cv, and finding the zone with a prefix of oxz_cockroachdb.
Log into that zone. This can be done using pfexec zlogin <that zone name>.
Read the CockroachDB log file to determine the connection instructions. This can be done with tail -f $(svcs -L cockroachdb), look for a line starting with RPC client flags:. As one example, this may look like /opt/oxide/cockroachdb/bin/cockroach <client cmd> --host=[fd00:1122:3344:101::3]:32221 --insecure
Run that command, with however you want to access cockroach. One notable <client cmd> is sql, which grants access to a SQL shell.
