Update from 1.18 to 2.x before or after hard disk upgrade?

I am currently with 2 issues:

• my HP Proliant Microserver N36L is currently still running version 1.18 (I have seen that some have a version 1.19 but my update manager doesn't give me update for a while now and I am still on 1.18).
• I am at the limit of my 1TB disks (I am running 2x 1TB in Raid1 and 1x 1TB as a internal backup disk where I manually trigger a mirroring of the Raid1 1-2 per week + 2 external HDD roating each Friday offsite). I have purchased two Seagate NAS HDD (ST3000VN000) to replace the current Raid1 and I will get the other 3TB disks in the next few days (1 normal desktop HDD for the internal backup disk and 2 external HDD for the rotating offsite backups).

Question 1: Should I upgrade to OMV 2.x before I install the new disks or after?

Question 2: How do I best insert the new disks? I assume that I have to configure all the shares new or is there a way to avoid this? What if I take one of the 1TB disks of the Raid1 out and insert one of the 3TB disks? Would the data be mirrored to the 3TB disk without a problem? And if I later replace the second 1TB Raid1 disk with the other 3TB disk, would I then have a Raid1 with 3TB or would I have a Raid1 with 1TB (throwing away 2TB of space - not gonna do that of course).

I am just wondering what the easiest solution is to subsitute the 2x 1TB disks form the current Raid1 with the new 3TB disks? The internal backup disk doesn't concern me much.

Would be happy about any hint and idea that you can give me. Would be great to know how experts would do the move.

So you would suggest a totally fresh install over just upgrading from 1.18 to 2.1?

I guess I forgot to mention that I have a small HDD for the operating system, then the Raid1 and 1 internal backup disk. I am less concerned about the plugins than configuring the shares and users (not a big deal, but it could take a bit until I have that back as it was.

When I check the update page in the OMV-Webgui, there is nothing showing up.

I didn't try to go via console yet, because I thought it was just that there were no new updates at the moment (I had seen the communciation that there will only be security updates for the 1.x version since the 2.x is out).

But then when I researched my issue here I found out that there is a newer version.

I will look into omv-update.

Hi!

Thanks for the response. Did the both first routines and got the following error:

E: The value 'stable' is invalid for APT::Default-Release as such a release is not available in the sources

I guess it is the same problem as here: OMV 1.18 CRON-APT Error: The value 'stable' is invalid for APT::Default-Release as such a release is not available in the sources

This is probably also the problem why my GUI doesn't show me any available updates, because "stable" is now the 2.x version and not the 1.x branch anymore. Thus it can't find the stable version of 1.x?

I didn't do the omv-release-upgrade part yet, because I want to check the installed plugins first, so that I don't run into trouble. Will check which plugins need to be deactived before the upgrade.

I followed the instructions in the other thread, removed this file and the update to 1.19 went through succesfully (via command line).

Now I'll check my list of installed plugins to see if I need to uninstall some of them for the upgrade to 2.1. I didn't see anything about deactiving plugins in this tutorial (Upgrade to OMV 2.x), but I remember that plugins can cause quite some trouble during upgrades to another big version. So I'll do some more research.

OK, looked around a bit, didn't find any problems in the forum, but deleted some plugins that I hardly use anyway and basically only left USB Backup active, upgraded and it seems that it has worked. At least I could access the webgui without a problem.

I will now look into how to put the disks there.

I guess I will have to delete the shares first, because otherwise I can't unmount the disks, then install the disks and then build the raid again.

Wish me luck...

Just one quick question: Does any of you guys have any hint regarding my other post (didn't receive any feedback in the Raid section, might be because it is not relevant or no one has an idea, but before I start...).

Which file system and how to format it

Thanks for the response, @tekkb

I didn't have any problems with EXT4 either, so I would probably go with it. I was just wondering, because as far as I know, each file system can be split up into sectors of a certain size or something and depending on the size of these sectors, you can loose some space.

I don't know, I am also far from an expert. But someone explained that to me once, when I asked why I should still have some space left on the disk, but I couldn't save anything anymore.

Will wait for a response from Aaron. Let's see if he has a tip for me. If not, with 3TB I should be fine for the next 2-3 years and then I can start to delete files from older projects (usually need to store them about 4 years and with some clients we have contracts that state 10 years).

Thanks for the reply. This was probably my other thread (where you also answered ). Aaron helped me there and I applied it with success. Freed up some 40 GB of my backup disk, so I can run it a little longer before replacing it.
