Strange RAID issues.

[Easy Rhino]

I seriously think that I'm going to resurrect my Phenom II and turn it into a server and rely on nVidia fake-raid since it worked really well with these drives.

if you are going to install linux then dont bother with the BIOS raid. ubuntu, centos, etc all provide very good software raid solutions without having to muck with the bios.

That doesn't help me with my problem now. I'm saying that I'll move my raid back to my Phenom II hardware if I can't get X79 to handle my drives correctly. I also don't trust software RAID. It leaves your /boot vulnerable where fakeraid using dmraid can actually boot a RAID device as /boot. I've done this in the past, but honestly, I don't like having multiple copies of /boot all over the place to make sure that all 4 drives has a copy of /boot in case any one dies.

well you mentioned maybe running ubuntu server with a samba setup. if that is the case ubuntu has really strong software raid that is faster and more effecient than the older onboard raid controllers.

As long as your CPU remains unbound.


Windows allows for hard drive configuration as well.

Simple, plus windows manages it.

Then my RAID-0 with my SSDs fails and my RAID-5 dies with it since Windows is gone. Windows RAID is a terrible idea, I like the idea of Linux sofware raid better. I think these drives are going back into the Phenom II system. Next time I refresh my RAID, I'll just get a bundle of WD Blues. Now if only 3x1tb drives could cost less than 200 USD.

So I ended up turning off this option on the RAID driver called "Patrol read" and basically the raid controller uses idle time to search the drives for errors. I disabled it and so far so good.

"Patrol Read" is a user definable option available in the Intel® RAID Web Console 2 that performs drive reads in the background and maps out any bad areas of the drive.

Patrol read checks for physical disk errors that could lead to drive failure. These checks usually include an attempt at corrective action. Patrol read can be enabled or disabled with automatic or manual activation.

A Patrol Read periodically verifies all sectors of physical disks that are connected to a controller, including the system reserved area in the RAID configured drives. Patrol Read works for all RAID levels and for all hotspare drives.

This process starts only when the RAID controller is idle for a defined period of time and no other background tasks are active, though it can continue to run during heavy I/O processes.
