Hi,

I am trying to set HA for dremio on Amazon ECS, but only starting one cotainer service and another one is failing with below error. Please note that the /opt/dremio/data is mounted to EFS.

## Lock file to RocksDB is currently held by another process. Will wait until lock is freed.

Is not possible HA for dremio?

@ashar.ma

This is the whole point of HA. In fact you have configured HA correctly. The second coordinator will come up if the primary crashes which will release the lock on the RocksDB. This HA is always active/passive

Thanks
