I'm curious, it sounds like you are not using RAID, but instead have 9 PVs in 
your LVM setup.

If one hard drive will fail in 5,000 hours of use, then 1 in 10 will fail in 
500 hours of use, or so the thinking goes.  With 9 drives, I'm not surprised 
that you are experiencing one failing.

If you're not using RAID, might I suggest that you do?  Those 9 disks would 
make a nice RAID5 or RAID6 array, and LVM works beautifully on top of 
software RAID, hardware RAID or any combination of both.

LVM does not provide redundancy (yes, I know it can do mirroring, but I 
wouldn't suggest that), it's about easily managing lots of storage space.  
RAID is about reliability/redundancy.  Use the right tool for the right job, 
and use both tools together to get all the best benefits of both.
