heh, I was a bit hesitant to say what it is, but it's fine I guess -
seeing as my previous post dealt on the matter of NAS devices :)
I'm installing Openfiler 2.3, which looks very very similar to the
CentOS installer. My reason for RAID 1+0 (like I said it doesn't
support RAID10) is for the higher level of redundancy & speed, and I
would like to utilize the drives to their max,
I've setup the /boot on sda1 & sdc1 (100MB each) on RAID 1, and then
configured sda2, sdb2, sdc2, sdd2 as 4GB swap each (no RAID), then the
remainder on sda3, sdb3, sdc3 & sdd3 as 2x RAID 1 mirrors - i.e. sda3
& sdc3 on /dev/md2 & sdb3 & sdd3 on /dev/md3.
Yet, I can't create another RAID, i.e. /dev/md4 of md2 & md3 combined,
nor can I tell the LVM setup to span md2 & md3 into the same volume.
So, now I'm stuck.
