"Remove inactive volumes to use the disk. Disk #1,2,3,4", ReadyNAS 204
I've read multiple postings here, offering advice on the error "Remove inactive volumes to use the disk. Disk #1,2,3,4." I am in need of assistance as well, circa 2024.
A few weeks ago, I experienced a disk failure (chan 0). I purchased a new disk of the same size (4TB). The NAS rebuilt successfully and operated without issues for over a week. However, I returned home one day to find a "btrfs_log_*something*" error displayed on the LCD screen. All disk numbers were lit on the panel at this time (the previous week, disk 1 (chan 0) was dark). I was unable to log into the admin console and holding the power button did nothing, so I powered down the device by unplugging it. I then powered it back up, and the device worked (after a resync). The same issue occurred a few days later.
I read about a potential memory full issue that could be related to snapshots. I turned off snapshots on the two shares that had them, which seemed to resolve the problem temporarily. However, I came home to find the device inaccessible again and could not log into the admin console. I unplugged the device again, and upon reboot, the device came back online and allowed access to the admin console, but not my shares.
Now, I am encountering the error described in the post title and have noticed an additional volume that was not present before. All disks now also present as red. "Data-0" volume shows a data size as 10.90TB, free space: 0, type: RAID-5. The new volume presents as data 0, Free space:0, Type: RAID unknown. This issue seems very consistent with previous posts on this forum. I was able to download a fresh set of logs a can send to anyone willing to take a look at them. I am keen to regain access to this array, as there are files on it that I do not have backups of (understanding the adage that "RAID is not backup").
I am more than willing to pay for NetGear support to help investigate/reinitialize the original array. However, due to the age of the device (2016), it seems that NetGear support may not be available.
I am seeking any assistance and would be happy to send your favorite bottle of scotch to anyone who can help before I consider enlisting a third-party recovery service.
I am technically inclined and capable of using SSH (which is enabled) commands. I would appreciate a dialogue surrounding this issue. Please let me know if you have any direction or ideas on how to resolve my predicament.

All ReadyNAS products are end-of-life, and Netgear only offers warranty replacements for the few that are still covered by the warranty.
The first step is to analyze the logs you downloaded.
If you want me to take a look, you can send me a private message (PM) that includes a download link to the log zip (dropbox, google drive, etc). Make sure the permissions are set so anyone with the link can download. Send a PM using the envelope icon in the upper right of the forum page.
FWIW, the message on the LCD screen indicates a crash - in your case within the BTRFS file system software.
