My recollection is that if any drive in an LVM fails the whole LVM fails.
LVM doesn't fail .. but hard drives do. If a hard drive failed that was part of the LVM, you would lose all that info, true. That is why one should use a CRC type RAID (1, 1+0, 5) under LVM ... (or LVM on top of RAID) :)
Then you can replace the failed drive and keep going.
Is there a simple way to install the system on LVM-on-top-of-RAID1?
I'd like to second this question. The other day I tried a CentOS 4.2 install on two IDE drives. My goal was to mirror them (software raid 1) and put them in an LVM so that I might, in future, add two more drives and add them to the existing mirror.
1) Is this possible? 2) If so, how? I could not figure it out despite trying what seemed like every combination of options in disk druid.
I succeeded in getting a RAID 1, but not in putting a RAID inside a logical volume.
Thanks, Matt
