Here is what I am trying to do:
Add a second WD RED 6TB HDD to my already existing OMV system, doubling the capacity to 12TB.
HP Z220 - Intel i5-3470
Version: 4.1.36-1 (Arrakis)
OS on 60GB SSD
1st (currently only HDD): 6TB WD RED HDD
Current backup method:
12TB External WD Elements HDD
(I purchased this in anticipation that I would one day double my server capacity, which I am finally doing.)
I use "USB Backup" to backup up my current setup.
My current HDD has finally reached near full capacity, (5.3TB used of the 5.4TB available).
I am looking for the simplest and safest way to add my second drive. I have read the FAQ on RAID and watched several Techo Dad Life videos, but seem to be a bit lost on what the best route is for me.
Here are my options as I see them:
1. Use Unionfilesystems to pool the drives together?
2. Use mergerfsfolders to pool together the directories?
3. Wipe the 1st drive, and use RAID 0 to combine both drives?
The risk with option three is that I did a crappy job backing up my data, and end up losing everything. I thought about practicing backing up my data on the new HDD just to see if I could do it, and if successful, push forward with setting up RAID 0.
FWIW, this is a home media server.
Sorry if this post is too long, or is just digging up questions that have been asked here before.
Thanks in advance for any suggestions or help.
