Firstly, I want to make it clear I don't care about data loss, and I understand the risks involved. What I'm looking for is guidance and if what I am hoping for is even possible.
I have 3 1TB SAS drives in the server. Wanting to combine to a main 3TB volume. OS is Ubuntu Server 14.04
I want to avoid using the RAID controller (RAID 0) since I know that if a single disk fails, then the entire array is compromised. I can comfortable use LVM but I'm not sure if it can do what I'm trying to do.
My goal is if ONE disk fails, then I lose the data on that bad disk but the other disks continue to operate in the array and the files on the good disks are still available.
I know this isn't technically "striping" because no data would span across disks (all blocks in a file on one physical disk) -- Is this possible?
One more time to reiterate - lost DATA is OK, but a lost VOLUME is not.
If it's possible, great, if not, that's fine too as I am just looking for guidance.
