Volume Stuck in Read-Only Mode - Resync Completed - BTRFS Error

[pressfit]

Hello,

We received an error from our RN424 RAID5 system today:

The volume data encountered an error and was made read-only. It is recommended to backup your data

This started a Volume Resync. After 9 hours, the resync was completed successfully but the volume is still in Read Only mode.

On checking the dmesg.log, we are seeing the following error:

BTRFS error (device md127): parent transid verify failed on 9133929988096 wanted 295954 found 295953

We are stuck and the have not found a proper solution from the forums. Can somebody please give us a solution/suggestion on this?

(a) FOLLOW THE ADVICE and back up the NAS.  DON'T reboot it until you have done that.

(b) Either

1. contact Netgear Paid Support (my.netgear.com) to resolve the problem
2. or do a factory default, set up the NAS again, and restore the files from the backup.
