Let's say I have two identical disks, and I set one LVM logical volume on them (no mirroring). Question: What will happen when one of the disks fails?
- I will lose all the data from all the disks
- I will lose the data from broken disk, but I get data from still working one
- something else (what)
Thank you in advance for clarification.
From what I've read mentioning RAIDs in LVM articles indicates I will lose everything, on the other hand shrinking LV indicates something opposite.
According to this article with linear mapping (default, it is my case) and no mirroring, in case of failure you should lose data only from broken disk. I hope it is true, and eventually I find out :-/
