This post mainly for documenting my process of changing my NAS operating system. I guess I have to explain why I am planning to switch NAS OS, but a short back story how I even started with Unraid. My colleague from my previous job introduced me to Unraid back in 2016. Based on my NAS requirements, Unraid met all that I needed for a NAS. I really like Unraid. I like it so much that I purchased another license for my off-site backup.
So why I decided to switch to OpenMediaVault?
Well, I may like Unraid, but I have encountered some problems that I have to find some alternative. These problems are:
- My USB flash drive died several times. Unraid users can only request a new license for the new USB flash drive once a year
- The docker.img keeps growing and I could not find a solution to this problem.
- I could not upgrade my primary Unraid to any version higher than version 6.5.3. This one is really a big deal. If I cannot upgrade my system, that simply means that it opens some vulnerabilities that I would have to deal with
- My cache drive somehow got corrupted three times since 2016. No idea what caused it.
If I can avoid these issues, I would. The flash drive issue I can live with it. The Unraid folks were kind enough to generate a new license when I had to reinstall a new Unraid to my third flash drive. The docker.img keeps growing, I can live with it even though it is annoying to delete the image then recreate it again. However, the problem with upgrading is something I cannot ignore.
I found a couple of NAS distros that I could use. The most popular one is FreeNAS, but it is based on BSD and I am not familiar with BSD. There is also
My requirements are:
- Easy to update
- UPS support
- Supports different disk sizes
- Parity drive(s)
- Docker containers
- Disk encryption
- NFS and SMB share
- Mobile friendly
- Bitrot protection
- Debian Linux (this is not require, but a bonus)
Currently, I still have my primary Unraid server, off-site Unraid server, and a spare HP Microserver N54L that I bought back in 2011, I think. I am going to use this spare N54L to install OMV for my onsite backup server.
The 10000ft view of my plan switching NAS OSes.
- Backup all data to off-site Unraid server
- Build an onsite (OMV) backup server
- Backup all data to the onsite server
- Install OMV on the primary box
- Recover the data from onsite backup server to primary server
This post is the beginning of my journey changing NAS OS from Unraid to OpenMediaVault. For now, cheers!
