Hi Support, My 104 crashed and not responding so I unplugged and restarted, now the existing volume is gone, the error on is "remove inactive volumes to use the disk, 1,2,3,4" are you able to help me restore the lost volumes ? Thanks,Dinh

This is the community, support is at netgear.com/support. You can send in your logs if you like (see the Sending Logs link in my sig) but you'll likely need to contact support (there would be some costs involved).

Thanks, do you know if there is anything I could try ?

I have noted a marked increase in posts about this type of problem since the release of OS 6.6.0. I think somebody at Netgear needs to look into why that is. The system should be more robust than this.

I got this myself tonight. Ultra 4 running 6.6.1. Did you ever find a solution how to retreive the volume?

Telling you how to re-assemble a RAID array without knowing the current status of the members would be way too dangerous.If you're able to retrieve the logs, you could look at systemd-journal.log. There should be lines containing "kernel: md" which would bring some light to the status of the members of your RAID. Look at sda3, sdb3, sdc3, sdd3 and md127.(I wish there was a log file containing the result of mdadm --examine of all the partitions, but it's not the case, so it doesn't make it easy to explain where to look.)

The Boot Menu is certainly not hidden, there is even KB articles about it. And if you do some research, you'll find info about Tech Support Mode. BJT this is for people who are proficient in Linux and know about mdadm and BTRFS.

Just to update everyone who might run across this thread with the same issue.

So I didn't want to pay support and was willing to lose all my data, because my HDDs has lots of ATA errors so I chucked them into the freezer (in airtight bags of course), I left it there for a few weeks, (because I had to buy a backup disk big enough to backup my data, hence the few weeks wait)

once I got my backup disk I put the drives back into the NAS and proceed to remove inactive volume and create new volume, and to my surprise the old volume came back intact with everything on it (I think all I did was click remove inactive then click new volume and the old one just came back, it didnt even asked me to put in a new volume name just restored itself). I am not sure if the fridge help or this error is merely a bug on the front end.

I also did try to run these commands, but it didnt seems to help

mdadm --examine --scan
mdadm --assemble --scan (with really force )

so yea I didnt lose my data and I now have a backup
