LVM and bad disk...

[John Burton]

All,

I've never used LVM under Fedora. I did use something similar under AIX 
probably 10-15 years ago. I've been using linux for since slackware (on 
floppies) and kernel version 0.99.4, but I've always used the old 
standard of partitioning hard drives and creating filesystems on those 
partitions (even terabyte raids :-). Now I'm considering using LVM for a 
fedora 10 system I'm setting up, but have one question. Under the "old 
way" if a disk dies, you lose the files on that disk that weren't backed 
up, but only that disk. Under LVM, if I have a logical volume that is 
made up of more than one physical volume, what happens if one of the 
physical volumes goes bad? Is the logical volume toast? Do you have to 
recreate the whole logical volume from scratch?

Thanks in advance for any help!
