ReadyNas 6 Ultra 6 won't boot or reset after power outage
After power outage, because of UPS failure, my RNDU6000 (ReadyNAS OS V6.10) stuck on "ReadyNAS" prompt screen :( Won't boot, won't reset :(
Do you see "no disks" status if you remove the disks (labeling them by slot)?
Do you have a backup of the data?
Yes, after removing the disks, I have no disks status and the display says "Booting / Finding disk" then "Starting network". After a few moments, the NAS started up in SAFE MODE. But I can't log into the NAS ... Unfortunately, I do not have a backup :(
Well, the issue is with the file system on the disks - since it isn't booting, that would include the OS partition.
I'd start by testing the disks by connecting them to a Windows PC (either with a USB adapter/dock or with SATA), and run the vendor diagnosics (Lifeguard for Western Digital; Seatools for Seagate).
After that, the options would either be
- to try using RAID recovery software (ReclaiMe is one package that supports BTRFS),
- use a data recovery service
- attempt to repair the file system yourself.
Thanks for ur help. How do I log into the system in Safe Mode? Can I just rebuild the RAID with data loss in this mode?

Normally you'd boot into tech support mode, and access the linux command line with telnet.
You can't just "rebuild the RAID" - you'd need to repair the file system. Risk of data loss is high, and you can easily do more damage when you attempt to repair it.
