Operating Systems Linux Help Setting up Linux Raid Server Post 302518595 by mark54g on Saturday 30th of April 2011 11:50:30 AM

Lore,

The chipset RAID is "NOT" hardware RAID. It is firmware + Software RAID and usually requires a driver for windows.

My suggestion is that you do the following: Leave the disks alone in a JBOD function (Just another bunch of disks), without spanning, and use the operating system's own software RAID. You will then be able to use any current Linux based operating system to manage the devices you created.

On my setup, using OpenSUSE 11.3, I have my device /dev/md0 as my /boot, /dev/md1 as my operating system volumes (in a volume group) and /dev/md3 (I skip md2 in case I need more for the OS, but that's a habit, it is not required) is my file store.

NAME
mfi -- LSI Logic & Dell MegaRAID SAS RAID controller SYNOPSIS
mfi* at pci? dev ? function ? DESCRIPTION
The mfi driver provides support for the MegaRAID SAS family of RAID controllers, including: - Dell PERC 5/e, PERC 5/i, PERC 6/e, PERC 6/i - Intel RAID Controller SRCSAS18E, SRCSAS144E - LSI Logic MegaRAID SAS 8208ELP, MegaRAID SAS 8208XLP, MegaRAID SAS 8300XLP, MegaRAID SAS 8308ELP, MegaRAID SAS 8344ELP, MegaRAID SAS 8408E, MegaRAID SAS 8480E, MegaRAID SAS 8708ELP, MegaRAID SAS 8888ELP, MegaRAID SAS 8880EM2, MegaRAID SAS 9260-8i - IBM ServeRAID M1015, ServeRAID M5014 These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and RAID 60 using either SAS or SATA II drives. Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers. All RAID configuration is done through the controllers' BIOSes. mfi supports monitoring of the logical disks in the controller through the bioctl(8) and envstat(8) commands. EVENTS
The mfi driver is able to send events to powerd(8) if a logical drive in the controller is not online. The state-changed event will be sent to the /etc/powerd/scripts/sensor_drive script when such condition happens. SEE ALSO
intro(4), pci(4), scsi(4), sd(4), bioctl(8), envstat(8), powerd(8) HISTORY
The mfi driver first appeared in NetBSD 4.0. BSD
