Well if you have hardware raid you have to RAID first anyway, otherwise |
| 2 |
you can do it in either order...However, I'd probably do RAID first, |
| 3 |
then LVM, as software raiding a bunch of virtual partitions probably |
| 4 |
takes a ton of processing power than LVM over software RAID. |
| 5 |
|
| 6 |
As for details...There are plenty of guides for software raid out there. |
| 7 |
Get that set up, you should have some /dev/md devices afterwards. |
| 8 |
Then just use the LVM tools to slice up the raid devices instead of the |
| 9 |
"actual" devices. IE give the LVM tools /dev/mdX instead of /dev/sdX. |
| 10 |
Then make sure you are mounting things properly ;) |
