gluster block storage CLI.
As of now, gluster-block is capable of creating tcmu based gluster
block devices, across multiple nodes.
All you need is a gluster volume (on one set of nodes) and tcmu-runner
(https://github.com/open-iscsi/tcmu-runner) running on same(as gluster)
or different set of nodes.
From an another (or same) node where gluster-block is installed you
can create iSCSI based gluster block devices.
What it can do ?
--------------
1. create a file (name uuid) in the gluster volume.
2. create the iSCSI LUN and export the target via tcmu-runner in
multiple nodes (--block-host IP1,IP2 ...)
3. list the available LUN's across multiple nodes.
4. get info about a LUN across multiple nodes.
5. delete a given LUN across all given nodes.
$ gluster-block --help
gluster-block (Version 0.1)
-c, --create <name> Create the gluster block
-v, --volume <vol> gluster volume name
-h, --host <gluster-node> node addr from gluster pool
-s, --size <size> block storage size in KiB|MiB|GiB|TiB..
-l, --list List available gluster blocks
-i, --info <name> Details about gluster block
-m, --modify <RESIZE|AUTH> Modify the metadata
-d, --delete <name> Delete the gluster block
[-b, --block-host <IP1,IP2,IP3...>] block servers, clubbed with any option
Typically gluster-block, gluster volume and tcmu-runner can coexist on
single set of nodes/node or can be split across different set of nodes.
Install:
-------
$ make -j install (hopefully that should correct you.)
Points to remember:
------------------
1. setup gluster volume
2. run tcmu-runner service
