how to move existing raid 1 disks from another system to OMV

germe · 21. Dezember 2017

Hey guys

I just built my new server with openmediavault (last stable)

the server has been installed on a 128 gb ssd with 2 partitions: 1 for OMV - 1 for additional data
i'm now ready to move my 2 raid mode 1 disks (3tb WD) coming from a nas zyxel nsa325v2.

do you know which is the best way to do the migration?

let's consider I have no more discs available but I can forgo the raid if it's necessary
for instance can i remove one mirror disk and copy data to this one? (just asking, i'm newbie with this stuff

thanks in advance for your help

I´d take the 2 disks, blank ém and fill them with the data from the backup.
You surely have a backup?

I don't have a backup.

Is Zyxel also using mdadm to handle the RAID?

If yes, they might be autodetected when OMV boots.

Would be a good idea to make a backup before. At least from the data you care about.

There are also some threads in the forums that deal with Zyxel. You might find the answer there or at least some users that have experience with Zyxel.

If it's running OMV then most probably yes

In fact his NAS box is a great candidate to let OMV run on it

@germe you should do yourself a favour, think about the meaning of RAID and backup, stop trying to re-use your RAID-1 setup (it's really just a crappy way to waste disks for nothing) and implement backup in the future if you store data that has any value on your NAS.

Hey @tkaiser your are right. I want to stop using the raid 1 setup. That's why my idea was to keep 1 mirror into the old nas and writing data into omv with the other disk. And implement an online backup for the future

Double post

Oh just to clarify i have stock software on the zyxel

hey guys my openmediavault server is now up and running

my configuration is now
1X3TB WD red EXT4 with 1.5 TB files inside
1X3TB WD red EXT4 empy

NO RAID

i finally have an external 3TB drive for rsync backup only

do you think this is the best configuration for me?

should i implement mergefs or snapraid or just use the current configuration and deactivate the second drive?

i mainly use the server for storing movies, music and pics and using
- minidlna
- logitech media server

thanks

Anyone?

I would rsnapshot the one internal drive to the second internal drive and keep the external drive physically seperated from the NAS (e.g. at a friend or at work). So if your house if flodded or burning down you still have a backup. Of course you need to update your external drive regularily.

You should also use your external drive to make regular images of your OS drive using clonezille.
