create cache for a group of disks
Project description
flashcachegroup (fcg)
===============
fcg makes fb's flashcache to cache a group of disks with one or multiple SSDs.
Group of hard disk(s) can be dynamically created , and caching can be applied
on the group instead of each individual disk.
Hard disk(s) can be dynamically added to or removed from the group on demand.
In case of a failure, SSD(s) can be replaced transparently, without interrupting
upper layers.
Requirements
=====================
Python
------
Python 2.6 and 2.7 (does **NOT** support Python 3.x)
Modules
-------
* flashcache
Install (Linux)
=====================
The easiest way to install is with pip::
sudo pip install flashcachegroup
Or manually (assuming all required modules are installed on your system)::
sudo python ./setup.py install
Usage
=====================
to create a new group by using hard disks:
fcg create [-h] [-g GROUP] [-d DISK [DISK ...]] [-c CACHEDEV [CACHEDEV ...]]
to delete an *UNUSED* group:
fcg delete [-h] [-g GROUP]
to replace broken SSDs:
fcg rep-ssd [-h] [-g GROUP] [-c CACHEDEV [CACHEDEV ...]]
