Hi there,
About a year ago I've installed OMV to a small PC. For the boot disk I used a CF card connected to SATA via CF to SATA adapter.
Then I plugged two 1TB HDDs and made a Linear RAID using them. Now I ran out of capacity so I bought one more 1TB HDD, plugged it to SATA port on my MoBo, How do I add it to my existing RAID?
Adding new disk to LINEAR RAID
-
- OMV 1.0
- nevermind

Dangerous idea. If one drive fails, you lose all data. I would look at using aufs or mhddfs using the unionfilesystems plugin.

When I try to add that new HDD to RAID I get the following:
Select devices to be added to the RAID device
Failed

What done is done, now I just need to add more capacity
There's no something important on that RAID, just some music and movies. So if even I lose all of them, I only will need to download them again (but it'll take some time) -
I don't think you can grow linear raid.

Why so? -

I have the same question, I'd like to grow my 12tb linear raid to a 15tb raid. Any possibility to do this without losing data?
