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.
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

StephenB I just tried booting in RO mode and it did boot. I can access the NAS with the /data partition in RO. I got the few filles that I needed from it...
I looked as the log; the last entry was "starting Balance"... I was running balance as the NAS started with 2 disk, then after it was getting full, a third disk was added, and then, after it was getting full again, the 4th disk was added.
I'm not thrilled about doing factory default and re-buiding the NAS as I will lose snapshots of files but, considering the problems I had recently, it's likely what I need to do...
What do I need to save before doing the factory reset other than the obvious (userids, groups, shares)? And, going forward, what should I check/backup to improve problem determination/likelyhood of fix/keeping the NAS Healthy? When should I update the OS to the latest (6.10.3)?
Do you recomend running a memory test and a disk test before doing the factory reset?
Thanks

It is a nuisance for sure.

I think you should look at the log zip file next - checking for disk errors and btrfs errors. disk-info.log, kernel.log and system.log would be good to check. If you see disk issues, then of course you need to deal with them. I wouldn't run a memory test.
You can save the configuration and then restore it after the reset. However, that might not get all settings, so it is useful to document what you have. Screen shots on the various pages is one way. Also, make sure you reinstall any apps before you restore the configuration.

On the first question, I do recommend running the maintenance functions on a regularly schedule. Personally I run each every three months (on a staggered schedule). Also, download the log zip files every couple of months and take a look at the disk smart stats in disk-info.log. Of course don't let the volume got more than about 80% full.
Also, I don't recommend using smart snapshots. I suggest custom snapshots, with retention explicitly set. Smart snapshots have indefinite retention, and eventually will fill the volume.
On the update question - no real advice there. I currently am running 6.10.3 (current stable release) and have had no issues with it. But staying with the long term stable release is reasonable too.
