General Advice or FAQ on Upgrade OMV 2.x (Stoneburner) -->3.x (Erasmus)

topi · 15. Juni 2017

Hi there,
according to the OMV blog entry "Release of openmediavault 3 (Erasmus)" of Volker, the lead developer of OMV, the upgrade procedure is described in the section Updates to OMV of the OMVWiki . However the blog entry also stresses that "Because of various database issues in OMV2 that can not be fixed during the upgrade you might run into troubles after the system has been migrated. So please consider to reinstall your system with OMV3.". With respect to this a clean install of OMV 3 is recommended in various postings in this forum. So I feel a little bit lost and confused with two options for an upgrade of a productive OMV 2.x system. Within this context my questions are:

What is finally the recommended way to upgrade a trouble free and productive OMV 2.x installation to a trouble free and productive OMV 3.x installation, especially for the not that tech-savvy OMV user?
If a clean installation of OMV 3.x is the recommended way to go, then what exactly does it mean starting from a productive and trouble free working OMV 2.x installation? How would I do a clean install of OMV 3.x ?
Is there some sort of FAQ regarding the OMV 3.x upgrade planned?

Thanks in advance,
topi

allways is more secure to do a fresh/clean install and configure services by hand, this works all times.

But you can try to upgrade OMV 2.x to 3.x, but to be sure that works my recomendation is to uninstall all OMV-extras plugings and OMV-extras too, this garanties that upgrade precess works fine.

I know that un-install plugings, upgrade OMV and reinstall plugings is not easy/confortable but is the secure way to avoid problems.

No, it doesn't. This makes it sound like the omv-extras plugins are the only thing that don't upgrade well. I've seen plenty of issues where debian itself doesn't upgrade well.

Make a backup. Try the upgrade process many times in a virtual machine. Moving from OMV 2.x to OMV 3.x is a huge change. I really don't recommend it for a non-tech-savvy user.

You install OMV 3.x the same way you installed OMV 2.x. Maybe use a new OS disk and keep the other one safe.

People keep asking for a wiki and/or advice on upgrades. omv-release-upgrade is the only thing you need. If it has problems, that would be almost impossible to document every problem that could come up.

Hi,

my current system is OMV 2.2.14 and I've stored my data on a RAID5 array.

If I do a fresh OMV3 install on a new OS disk: what is about my data on the RAID5-array? Would it be found by the new OMV3 system and could just be added and mounted?

Best regards
Freed

yes, data are safe, and can be mounted from webGUI
