Hi,
I have a little HP micro server. I was running freenas with 3x2TB drives in a RaidZ1 config until I began running low on space and got another 2TB drive and realized I couldn't grow my volume. I'm now on omv and so far it looks great, but I would like to add some redundancy so here's my story. I initially planned on using snapraid to try and replicate the above setup (I'm okay with a bit of data loss if snapraid isn't completely up to date) so my plans were to have my 3 2TB drives containing media and the 4th drive as the parity drive. I didn't want to manage each drive independently so I created a lvm so I could just copy files over and let the lvm deal with the rest. That worked great whilst I performed the risky move of degrading my old freenas setup to 2 drives and copying data across to my new 2 drive lvm. I have since wiped formatted to ext4 and added the 3rd drive to the lvm and the 4th drive (will be parity) as a separately mounted drive.
I'm now:
LVMVolume 3 2TB drives
Parity drive 1 2TB drive
I then installed snapraid and as I have only one mounted volume (the lvm) I can't use my parity drive as it's too small. I would need to somehow mount all the partitions in the lvm separately to get this to work as intended. Is there a simpler way to do this or am I looking at the wrong solution here? Also what would happen in lvm if one of my drives failed would I lose everything or just that disk? Perhaps dealing with each drive on it's own would have it's benefits then? I did try searching for some results here but struggled finding something that seemed to be the same as my issue.
Thanks in advance.
