Description Atin Mukherjee 2016-07-07 04:30:49 UTC

+++ This bug was initially created as a clone of Bug #1353156 +++

Description of problem:

There is no existing CLI that can be used to get the current local state representation of the cluster as maintained in glusterd in a readable as well as parseable format. The existing "statedump" infrastructure dumps stats related to memory allocation for a daemon by passing SIGUSR1 to it. This while useful for debugging purposes, does not reflect the local state representation of the cluster.

Expected results:

# gluster get-state [DAEMON] odir <path/to/output/dir>

This would dump data points that reflect the local state representation of the cluster as maintained in glusterd (by default if no daemon name is specified) to a file (say glusterd-state) inside the specified output directory. The option for specifying the daemon name would leave room to add support for other daemons as well. This data if required can then be parsed by external applications to represent the cluster state as obtained from glusterd in any other model.

Verified below things using the build glusterfs-3.8.4-2.

1. CLI and it's options // gluster get-state [DAEMON] odir <path/to/output/dir>
2. Tested for all volume types.
3. Tested all the entries mentioned in the file.
