ReadyNAS Pro 6 - Stuck on booting while checking fs

The root fs check is where it is hanging. Can you (or someone rebuild that partition like mdgm​ / mdgm-ntgr​) so it boots back up? I can then grab the data off it and then reset the NAS to factory and recreate the volume again (obviously).

It does mount. However, how do i get it off to another drive since I can only boot into Tech Support mode? I have an enclosure with 13.5 TB free but it is eSATA only.

 

Is there a way to get the unit to boot w/o trying to do anything with the /dev/md127 volume so I can then mount it in readonly and copy the data off across teh network?

Getting SMB and similar services running in tech support mode is tricky.  

You can try unmounting it with umount, and then see if it mounts as read-write.  Just mounting read-only (as you did) can resolve some issues.  If it does mount read-only then you could try a normal boot.

Another option is to disable quota on the BTRFS volume ( btrfs quota disable /data )  Then try a reboot.

I understand that is what you saw on the LCD panel.  But running that check manually on the root in tech support mode didn't turn up any errors (and did not hang).  So I don't think that the LCD screen is giving you the right information.  Your issue appears to be with the data volume, not the root file system.

I cannot rebuild the OS partition (and I don't think it would change anything in this case).  mdgm no longers works for Netgear, and hasn't engaged in this forum for some years.
