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.
