glusterd/cli: cli to get local state representation from glusterd
Currently there is no existing CLI that can be used to get the
local state representation of the cluster as maintained in glusterd
in a readable as well as parseable format.
The CLI added has the following usage:
# gluster get-state [daemon] [odir <path/to/output/dir>] [file <filename>]
This would dump data points that reflect the local state
representation of the cluster as maintained in glusterd (no other
daemons are supported as of now) to a file inside the specified
output directory. The default output directory and filename is
/var/run/gluster and glusterd_state_<timestamp> respectively. The
option for specifying the daemon name leaves room to add support for
other daemons in the future. Following are the data points captured
as of now to represent the state from the local glusterd pov:
* Peer:
- Primary hostname
- uuid
- state
- connection status
- List of hostnames
* Volumes:
- name, id, transport type, status
- counts: bricks, snap, subvol, stripe, arbiter, disperse,
redundancy
- snapd status
- quorum status
- tiering related information
- rebalance status
- replace bricks status
- snapshots
* Bricks:
- Path, hostname (for all bricks these info will be shown)
- port, rdma port, status, mount options, filesystem type and
signed in status for bricks running locally.
* Services:
- name, online status for initialised services
* Others:
- Base port, last allocated port
- op-version
- MYUUID
