RN2120 - device offline issue #25406155
Hi, Not sure if I'm posting to an appropriate topic, but it seems that I have a problem with RN2120 - it gets to a "device offline" error right after booting up. The drives are WD30EFRX-68EUZN0 ...

I tried to follow the steps at this topic by @mdgm - viewtopic.php?f=50&t=75900#p422576 - reconnecting the disks to an ubuntu box and running mdadm/mount btrfs:
- mdadm --assemble --scan assembles an array at /dev/md127, but attempt to mount it causes kernel bug in btrfs/file.c error (according to dmesg).
- btrfs shows appropriate size of the filesystem, but that does not bring much info for me at the moment.
Those steps are a last resort. It's possible you used a kernel that is too old or too old a version of btrfs-progs or that there is a problem with your volume.
Did you contact support? If, so what's the case number?
