ReadyNas Pro4 does not boot - at 85% fvbackup-q.service - Management service is offline
Hi, My ReadyNAS Pro 4 will not boot anymore. It keeps hanging at 85% fvbackup-q.service, Raidar shows Management service is offline, and I can't login the admin-page anymore. I have already r...
Of course the issue is here:
3.1G /mnt/media/media only should contain mount points for USB drives (e.g., USB_HDD_1,etc). These mount points should be empty. So look in each subfolder and delete the files you see there (leaving the mount points).
Files can end up in these folders when a USB drive disconnects when a backup job is running.
FWIW, remounting the root as /mnt is useful when the NAS is running normally, as it keeps the mounts out of the way. It isn't needed in tech support mode, as nothing (including your data volume) should be mounted on a root folder.

Do you have SSH enabled so you can check the OS partition use? The other poster still had SSH access when it failed to fully boot.
I can't remember that I have enabled it on OS6, since it's default is OFF, I would say the SSH is disabled.
Also, I have tried to SSH it with Putty (port 22), the response is "Fatal Error, Network error: Connection refused". I would again say the SSH is disabled.
However, I am able to reach it with Putty>Telnet from Tech-support mode.

Then you can check the OS partition. First run
rnutil chrootThat will start RAID, mount the OS partition, and chroot.
