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?
