ReadyNAS RN214 check root fs - booting 47% - stalled
round I have a RN214 runninfg V6.10.2 (downgraded from V6.10.3 a month or 2 ago). I had to unplug the unit after it became un-responsive (again) but this time, instead of rebooting normally, it ...
If the NAS is used, then Netgear won't provide paid support. readynasd is the Netgear NAS application itself.
Have you tried booting up the NAS read-only? Probably worth doing before you try going into tech support mode.
Though if this isn't critical, I'd suggest just doing a factory default and rebuilding the NAS.
The btrfs errors cause me to suspect the /data filesystem is corrupted (though it does sound like root is messed up also).
Do you have a backup of the data?
I have found readynasd to be very problematic when it is having difficulty accessing the volume, be that during a sync, scrub, or because of a problem with the volume as you seem to be experiencing. It will ultimately reach 100% CPU usage and lock up the NAS. This behavior has been reported to Netgear via the forum multiple times, and mostly ignored. When not completely ignored, they say they can't re-produce it.
My speculation is that it just keeps stacking up failed drive access attempts until it runs out of space and/or throughput. It has no "escape clause" that would at least exit and report the problem.
Of course, even reporting a problem would likely not solve your issue; though it may give you more clues as to how to solve it.
I agree with your assessemnt that somebody likely needs to go in in support mode and try to fix it. Are you looking for instructions on how to do that yourself or how to get support from Netgear?
SandsharkI am looking preferably for instructions on how to repair/replace the main filesystem so I can fix it myself if it ever happens again.
I bought that NAS used so I have no formal support. I would have to check how much Netgear charges for looking into this and fixing it (assuming they charge only if the repair of the main filesystem is sucessful)...
I have seen posts from members of this community fixing similar problems so that is an option too...
What is the purpose of readynasd? Is there supposed to be more than 1 active at any given time?
Thanks

StephenBThis now failing NAS is use to backup 3 other NAS that I own. I am exploiting btrfs snapshots to keep multiple versions of files that changed on the 3 other NAS.
There is a few files that I'd really like to get to on the /data partition but, assuing the none of the other 3 NAS dies on me, I have no critical data on the failing NAS that I cannot recreate.
Should I have seen warnings about the btrfs errors? Was there a way to check the health of the btrfs /data partition before it died on me?
Thanks.
