Western Digital 1TB Hard Drive
A few months ago, I bought a Western Digital 1TB Hard Drive (http://www.wdc.com/en/products/products.asp?DriveID=336) for my server.
Since every WD drive I have bought in the past has served me very well, I assumed this drive would do the same…. but VERY annoyingly, I just got an email from smartmon tools telling me that there are an increasing number of bad sectors on the drive! 
eBuyer has agreed to replace the drive since it is still under warrenty, but the problem is that I have the drive in an LVM volume group, so backing up the data is a little difficult.
It would be easy if I had another 1TB Hard Drive to add to the volume group, the pvmove all the data off the broken one, but I do not have a spare 1TB drive, and eBuyer (naturally), didn’t agree to sending me the new drive before I give the old drive back to them.
I also have 1TB Seagate drive in the volume group, which is performing very well, so very reluctantly, I might just ask eBuyer if they would let me switch it for a Seagate one.
Oh well, I guess for now, my only option would be to buy another 1TB drive, move all the data onto that drive, remove the old drive from the VG, get it replaced, then if I feel brave enough, add the new one to the VG. I’ll have quite a large volume group if I do that (3TB!).
Speaking of which, if anyone has any tips for boosting LVM performance when using large volume groups, please tell me!
