I'm building a NAS using Openfiler2.3 (from 32-bit ISO), first of all I want to experiment it on VM first before going out and buy the harddrives needed.

I created 5 virtual drives on VMware, sda is 2GB and the rest 1GB each (sdb to sde).

I left sda blank and want to setup a RAID 10 disk using sdb, sdc, sdd and sde, 4 RAID partitions are setup successfully, but when I try to create a RAID device the only option for RAID level is 1, 0, 5 and 6.

RAID 10 is not there!

Can someone let me know what have I missed, please?

TIA.

You should create two raid-1 arrays and then create a raid-0 on top of their respective md devices. Or vice versa if you prefer 0+1 instead of 1+0

how is that possible in Openfiler? –  user41653 May 4 '10 at 9:20
    
I don't have one in front of me right now, but try to create two raid-1 arrays, one on sdb+sdc and second on sdd+sde this should create two raid arrays - md1 and md2 (or mda and mdb) Then you should try and create a new raid-0 array using md1 and md2 –  dyasny May 4 '10 at 9:42
    
That's not possible, thanks anyway. I found the option after Openfiler is installed, it's on the web interface, so the lesson learned is that one has to install Openfiler first on a partition that isn't prepared for the RAID array, but then the issue is that what if the boot partition fail? –  user41653 May 4 '10 at 16:05
    
    
The option I found is in the Web UI but the "add array" button is greyed out. Does that imply I have to create the RAID manually as suggested above? –  user41653 May 5 '10 at 17:25
