This morning I was reading through http://www.amahi.org/faq#Does-Amahi-support-LVM and found this warning in the FAQ.
Note that using two or three more drives will double or triple your chances of having a file system catastrophe due to a hardware failure.
Does this warning apply to me? I have 4 drives, but am not using LVM to consolidate these drives in anyway. My LVM setup was provided out of the box by Fedora's installer, with everything on a single drive containing a small partition for /boot and the rest of the drive used by a large LVM partition which holds sway, /home, and / . The other 3 drives were added after Amahi was installed, and are used by my greyhole pool.

The FAQ goes on with a second warning.
unless you are familiar with LVM, we tend to nor recommend it due to the risk that one drive's failure makes it difficult to recover the data from the other.
Does this warning apply to me? From what I learned today, I do not see this Fedora's default LVM setup poses this risk even though I'm not at all familiar with LVM. When the FAQ author says Amahi do "nor recommend it", by "it" does the author mean Amahi do not recommend LVM itself or does the author mean Amahi do not recommend using LVM to consolidate many drives into a logical volume?
