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.
Hi jetheroheller,
If you don't have a backup of your files, boot the device in Volume Read Only mode and see if they'll be available. If this works, start backing them up then we'll work on your main issue afterwards.
Kind regards,

It's ReadyNAS Ultra 6 + (RNDU600) running R4toR6_6.4.2.bin (OS 6.4.2).
The disk that was hinting at failing looked fine w.r.t. SMART and tested fine with WD Diagnostics, but had 9 pending sector counts. That was the only hint I caught, and only showed up as a caution in CrystalDiskInfo, showed up as test passed WD Diagnostics. There were no emails from the NAS or other errors.
I haven't tried booting without that drive because I wanted to exhaust the diagnostics before triggering something that might result in a resync event, if possible.
So what's next? I'll try to figure out how to trigger volume read only mode, but otherwise, what do we do?
I have just sent you a PM with the details of what we can try if volume read-only mode (on legacy NAS running OS6 this is triggered if you select the skip volume check boot menu option)
mdgm-ntgr - skip volume check also gets me to "booting...checking root FS" and hangs. I'm not sure how long it should take, so I'll let it sit there for a bit while I check out your PM.
As I suspected you have seen the same issue still.
Booting the data volume read-only doesn't help when the problem is with the filesystem on the root volume.
