Rebuilding the NAS would be a big frustration for me to be honest as sending over the data via internet would take a very long time. Hope we can stay away from this.
I think the best way to deal with this is to rebuild the NAS. One reason is the dm-0 is the OS partition, not the data volume.
Paid support might be able to fix it remotely though - since you have access to the web ui, you should be able to enable the diagnostic mode.
Hi StephenB is this diagnostic mode something that I can do or only paid support and how can I contact them? The NAS by the way seems to be doing everything that I expect it to do including disk checks, which finish normally. The status shows as Healthy on the overview tab as well by the way. The only thing is that the volume is read-only meaning that it can't be used as a back-up. I am now close to it so I can do a restart or other things as well. The uptime of the NAS is more then 61 days so the issue with my volume did not occur due to a power outage (and it is behind a UPS as well so will be shut down safely in case on a longer power outage). I can't think of any reason why my volume got issues all in a sudden. This is worrying me as I choose the RN628X to have reliable equipment. This has not been the case for me so far. On my main NAS I had to SSH into it with the help of a colleague of mine to delete files that without any reason were created and were eating up system space so that 90% was occupied. And this second RN628X which now has a volume issue is already a replacement as the original RN628X got bricked due to a firmware update. Definitely not something I would expect from these devices in my usage cases. Anyway back to the topic I do hope that the NAS can be fully functional soon without a new build up as that will take a very long time for me to sync the data over internet. Would a reboot be something that I should try?

That is not normal, and indicates that the volume isn't healthy. You can of course set up shares with read-only access - but a read-only volume is quite different. The NAS makes the volume read-only when it finds a problem - in order to protect your data.
You should definitely make a backup if you don't have one.

There are modes that Netgear can use to log in remotely. Diagnostic mode is a setting in the admin web ui, and you can't access the NAS that way. There is also tech support mode - which you get into from the boot menu. You can access the NAS using telnet in this mode (you end up running the linux command line, similar to ssh).
In any event, you access paid support via my.netgear.com. You don't want the gearhead support (that isn't for the NAS). Ideally you'd get per-incident support.
