Usage: nomad operator raft info <path to nomad data dir>

Displays summary information about the raft logs in the data directory.
|

|
|
This command requires file system permissions to access the data directory on
|
|
disk. The Nomad server locks access to the data directory, so this command
|
|
cannot be run on a data directory that is being used by a running Nomad server.
|
|
|
|
This is a low-level debugging tool and not subject to Nomad's usual backward
|
|
compatibility guarantees.
