ReadyNas RNDP6000 Array offline no disk failures.
Help! one of my 2 RDYNAS Pro 6 units (Both running OS6) locked up the other day with a kernal error from btfrs showing in the ui. I powered the unit down and after that the disk array now shows offline yet all disks show as healthy. When I login to the UI it shows two different 6 disk arrays one as Raid5 and says i need to delete that one to use the disks (DIsk 1,2,3,4,5,6) and the other it says unknown raid level but it will also let me remove that one if I wanted to. This was my backup destination nas however it has 500GB or so of downloads that I'd like to get off of it before I factory reset it. Can anyone help?
Thanks,
Kirk

It appears to be a btrfs problem with journaling. Seems that when the kernal panic happened the unit kept writing data and som part of journeling continued to work but now I get a mismatch.
Here is what I see in the console when I try to mount the vol.
root@DATA:/# mount -t btrfs /dev/md127 /mnt/test
mount: wrong fs type, bad option, bad superblock on /dev/md127,
missing codepage or helper program, or other errorIn some cases useful info is found in syslog - try
dmesg | tail or so.
