"No volumes exist" after attempting to replace a drive

[Dilemma]

I've had my ReadyNAS for several months. I began with 2x3TB drives, and ended up expanding it to 4x3TB using X-RAID. The unit has worked well. I decided to expand the array by installing larger drives, so I purchased a 6TB drive that was on the ReadyNAS compatibility list. After upgrading the firmware to the latest 6.6.1 OS, I removed one of the 3TB drives, and installed the 6TB drive. Shortly afterward, the system reported that the array was degraded, and started a resync. At this time, the data was still accessible, and appeared to be running well. After a few minutes, the shares were inaccessible, and the web interface was no longer responding properly. I left the system in this state for 90+ hours, hoping that I just needed to give is time to resync. When I have all four drives (3x3TB +1x6TB) installed, the system will not boot up at all, as it will report that it failed to boot. If I remove the 6TB drive, and attempt to boot on the other 3x3TB drives, the system will start, but reports the following:

• Remove inactive volumes to use the disk. Disk #1,2,3

When I click on "Shares" I receive the followin error:

• No volumes exist

All three drives are displayed in orange on the "Volumes" page.

At this point, if I install the 6TB drive into slot 4, all 4 bays are displayed in orange, and the "Remove inactive volumes" error includes "1,2,3,4" in the error.

I have attempted to contact support, however the phone line tells me I have to purchase a support agreement. When I attempt to look as the support agreements, I'm unable to figure out how to choose and purchase a support option.

I am using this device primarily to store videos for home use, and the device is not used in an office

My most important data *should* be backed up, but I'd still like to attempt to recover any usable data if possible

I'd like to know how to purchase a single incident support plan for this issue, or determine any other options available.

I'd like to know if there are any commands I can do to attempt to access the data on the array

Can you send in your logs (see the Sending Logs link in my sig)?

Thanks. This is definitely something for support. From what I can see you have not yet registered your device?

You should go to my.netgear.com and register your device. That would be the first step.

Thank you for your assistance, I have purchased a 3 year support plan and have submitted a support request.
