Upgrading from OMV3 to OMV4 when using Snapraid

Mr. Anderson · Jan 7th 2018, 11:17pm

Hello everyone,

I've been looking through the forum but wasn't able to find a definite answer to my problem.
I'm currently running OMV3 (3.0.96) and thinking about upgrading to OMV4. However, since I'm using Snapraid with mergerfs I'm not sure if I can just run omv-release-upgrade or if I have to take any precautions like disconnecting the hard drives or similar.
Can anybody shed some light on this or refer me to some guide or wiki?

Thanks!

Just run the upgrade, and from personal experience, if you disconnect your data drives the upgrade will not go well.

Worked for me without unmounting

Disconnecting the data drives is a new installation recommendation because you are selecting where to install the OS. This does not apply to upgrades because there is no partitioning or formatting involved.

How did the upgrade go? I've been thinking about updating also but wasn't sure how it would afftect my data and Plex server. Also how do you like the Snapraid/mergerfs set up? I'm wanting to set that up but, same thing, wasn't sure how it would affect my drives/data and plug-ins, mainly Plex.

Did the update. No problems. Just omv-release-upgrade.

Snapraid/mergerfs set up. No unmounting/disconnect before update.

But always have a backup ready in case something goes wrong
