Does the server have a RAID card? Looks like the drives are in HW RAID0.
It is raid 0
I am sure 100%
Nope, but i'm starting to think that the disks are in an LVM partition..
Try vgdisplay.

Yes, its an LVM partition. You will have to reinstall the OS if you want to setup SW RAID10.
Will do that, seems like i gotta wait for KVM first -.- (Dacentec)
Dacentec is generally very fast in granting KVM access. Never made me wait for more than an hour at most.
It's the weekend now, so don't expect fast KVM setup.
Just found out that it does have an LSI, but i can't seem to get into the configuration screen upon boot.. It tells me i need to press F8 but it just keeps on booting debian whenever i press that button lol
Edit: It was a problem on their end, got fixed now
And yes, the disks were in RAID0...
Hmm... It's the HP raid controller thingy, I forgot which button to press. By the way I left a 4xSAS server with RAID0 when cancelling on December 20th. Coincidence?
iirc Dacentec has a provision module in the control panel which allows you to provision CentOS 6.4 with SW RAID10 ready to go. Could try that ?
The RAID controller (on-board/fakeraid if I'm not mistaken) should be modified first. If it is setup in RAID0 then even their provisioning module can only detect 1 disk - no software RAID possible and it will return missing disk or something like that.
ahh yep, missed that part :P
Don't know, got the server with 4 SAS disks today (Had one with SSD first, but cancelled and ordered the SAS one). HP LSI was configured @ RAID0 though
I disabled RAID at the HP LSI right now
I never knew that haha. Found it.
It's pretty neat, a few OS's had an issue when I used it at the start (early last year) but they seem to have resolved off those issues and it's pretty awesome now, loads of CentOS templates and disk layouts available for VPS provider setups (OpenVZ/KVM etc)
you need ask dacentec replace your raid card, because current one doesn't support raid10. very simply, just ask and they replace for you within one hour
Then, your server will be raid10 hardware by default, just select centos 6 latest at provision
Raid 5 will give you better performance than raid 10 in this case
