Topic: Hardware Raid and SME Server

[Joeg1484]

Hey again,

Ok, I got me a 3ware  8000 series RAID controller from work and set it up as a RAID 1 in the bios. All is well and the OS sees the raid device. However, SME server tries to set it up as a software raid and presents a /proc/mdstat with the following information:

Code: [Select]

Personalities : [raid0] [raid1]  [raid5] [raid6]
md2 : active raid1 sda2[0]
         1465031488 blocks [2/1] [U_]

md1 : active raid1 sda1[0]
         104320 blocks [2/1] [U_]

unused devices: <none>

This is interesting because the hardware raid should only present to the OS /dev/sda (As it does with other versions of Linux when I tested) and SME should not try to set up software raid (Or at least, this is my impression)

Also, if I try to install with sme noraid at boot up, it knocks out one of my drives in the 3ware bios and sets it to "not in use".

Any ideas? Should I leave it as software raid as it currently is and just trust the hardware raid to mirror them, or is there something else going on.

I have tested with Ubuntu Server using eBox and with Arch Linux and they see the /dev/sda as I believe it should be presented to the OS; as /dev/sda and not a raid device. Both Ubuntu and Arch have more modern Kernels, so they might have updated 3ware drivers?

Thanks!

Joe, please take some time to read carefully the documentation..

SME will always create a sw raid if you don't give the noraid option

Ok, very good. I just was not used to seeing that, but if that is how its done, then thats great. Just wanted to make sure I was not doing something wrong.

And, yes, I do need to spend some time with the Documentation!

Thanks!!!
