RNDU600 stuck at "Booting... checking root FS"
Running OS6.4.2 on RNDU600 on 6 2TB drives set up as RAID-5. When either hard or soft shutdown, upon powering up the LCD gets to "Booting...checking root FS" and stays there. It's been there for 16 ...
Update:
in private message, mgdm got me to send him a image of my corrupted file system for analysis through tech mode, then was able to reset the os remotely.
System booted without issue, but needs to be reconfigured.
The data volumes and all of the addons were present.
I was able to restore my config from a recent backup and restart the system, getting my configuration back.
Some add-ons worked (plex) while others did not (transmission, sickbeard).
But at least the NAS is back up and I can start to fix things.
Thanks so much mdgm-ntgr.
attempted the boot menu 'os reinstall', but still locked up at 'checking boot FS'. Not sure if the OS reinstall was successful (i.e happened before the 'check boot FS' failure) or didn't happen (i.e. check boot FS failure prevented reinstall of OS)
- RAIDAR from my PC, nor ReadyNAS cloud, can detect the unit while in the booting state.
Scouring the forum for similar posts...
I read through this troubleshooting, and nothing here seems to match. However, i am currently doing the built in disk test from the boot menu to see if I can detect failed disks. I normally get email SMART alerts before a failure, and I've tested the only one that has ever given a hint, so I'm not expecting a failed disk, but one never knows.

- YAY, RAIDAR CAN detect the array during DISK TEST. First time I've seen the NAS communicate in a few days.
Depending on the outcome of the disk test, is it possible it's my flashed firmware? Should I attempt USB recovery?

Based on this post:
What errors was the disk that was hinting at possibly failing giving? It sounds like there may be a problem with the root filesystem on the disks in which case it might not be possible to boot into volume read-only mode. If you can't boot into volume read-only mode we can discuss what the next appropriate step is.
No, this problem doesn't suggest that there is anything wrong with the firmware on the internal flash so doing USB Boot Recovery would be a waste of time and if anything may introduce a new problem.
Also as you have an RAIDiator-x86 4.2.x unit if you were going to do USB Boot Recovery you would use the USB Recovery tool for RAIDiator 4.2.x (but you could use OS6 firmware renaming it to RAIDiator-x86-something).
