What is FlexRAID?

FlexRAID is a highly scalable and smart storage system that turns independent hard drives of various sizes, makes, and models into storage pools and storage pools into storage clouds.

Additionally, FlexRAID provides both snapshot and real-time parity data protection with support for RAID4, RAID6, and RAIDX where X is any number of tolerances desired. Parity data protection can be configured at the storage pool level and/or at the storage cloud level.

Furthermore, FlexRAID is not limited to hard disks as it can pool data from all accessible sources including removable media, external storage, network shares, LUNs, disk arrays, etc.

NOTE: Ensure you turn off Greyhole and disable it permanently as shown in Greyhole Disable Section. THey SHOULD NOT been run together and could produce disastrous results.

Create Init Script (Not Working)

• To enable FlexRAID to start on boot, create the file named flexraid and insert the following text:

#! /bin/sh
   
# by wyld
### BEGIN INIT INFO
# Provides:          FlexRAID application instance
# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts FlexRAID app
# Description:       starts instance of FlexRAID app using start-stop-daemon
### END INIT INFO

        echo "Usage: $N {start|stop|restart}" >&2
        exit 1
        ;;
esac
   
exit 0

• To enable the script to run on boot, do the following:

install -m 755 flexraid /etc/init.d/
/sbin/chkconfig flexraid on
/sbin/service flexraid start

• To start/stop the service:

service flexraid start
service flexraid stop

• To check service status:

service flexraid status

Post Install Questions

• Does Greyhole need to be disabled?
• Does this work with LVM disks?
