Issues with NV+

I have been using my NV+ for several years without issue, but the other day when trying to access it, I lost all access to my shares and it was reporting 0MB/0MB in frontview.  On the NAS display, it was saying the correct storage.  I tried several things, volume scans, removing drive 3 (of 3), and resyncing it, but nothing worked.  I ended up reinstalling the firmware via the reset button, and now frontview reports the correct storage, however the webpage is pretty much unusable, as it says everything is undefined.  Radiator reports all my drives as green.  Also from within Windows I can see all my shares but it's asking for a username/pw, which it's never done before.  

 

From my research i'm guessing my log files are too big, and causing me issues.  I have lost SSH access at some point, so I can't do much about it.  I have pretty much all important data backed up, so I'm not too worried, however I have a bunch of data that's not backed up, that I'd rather not lose if possible.  I've read that some moderators may be able to remotely access my nas and then clear off these files, to give me more room on the OS partition.  Not sure if that's an option.

Re: Issues with NV+

It does sound like a filling OS partition.

 

A Netgear Mod could offer courtesy help; other options include (paid) per-incident support from Netgear, and booting the system into tech support mode yourself, and useing telnet to access the system.  That last option requires that you mount the OS partition manually.

 

Another approach is to connect the disks to a PC, and back up the remaining data.  Then do a factory reset/rebuild the NAS.  R-Linux for windows is one tool that I've heard will work.  Or use a linux "live cd" and this procedure: http://home.bott.ca/webserver/?p=306

Re: Issues with NV+

I've found these two links, that you've commented in, but I think I need a bit more info before attempting.  

https://community.netgear.com/t5/ReadyNAS-in-Business/Pro-not-booting-after-downloading-log-files/m-...

https://community.netgear.com/t5/Using-your-ReadyNAS/Readynas-NV-Frontview-Inaccessible-How-to-fix-w...

 

How do I start the RAID?

Where do the log files live, after I mount?

 

Here is what I think the process is:

1. Put into Tech Support Mode (Hold Down Reset, Power On, Wait till you see Boot Menu, Release Reset, Use backup button to select Tech Support, Reset Button again?)

2. Telnet into NV+

3. start RAID (how?)

4. mount OS partition

5. cwd to log file location (where is this?)

6. rm *.log files (what are the filenames I'm looking for)?

7. Now what, restart via power button?  Reinstall os again?

It's best not to delete them.  Truncate them to 0 size instead by using 

echo > logfilename.log

 

The logs are in /var/log.  You should be looking for large ones (hundreds of megabytes).

Re: Issues with NV+

I'm making some progress.  I'm telneted in, and have started the RAID and mounted.  However the df commands give me: df: not found

 

I go into /var/logs, and see a bunch of stuff (including a bunch of *.log.old.old.old, etc files)

 

I just need to know what to delete

Re: Issues with NV+

More progress, had to run the command with the path (my unix is very rusty).  

 

My os is indeed full:

/dev/hdc1             1.9G  2.0G  8.9M 100% /sysroot

 

when I do a: 

/sysroot/usr/bin/du -csh /sysroot/var/log/*

 

It looks like the offending file is 

1.5G    /sysroot/var/log/upnp-av.log

which is 1.5G of my 1.6G of log files.

should I just delete this using rm?

echo > /sysroot/var/log/upnp-av.log is better.  The file will still be there, but it will be empty.

Re: Issues with NV+

Awesome did that and now getting: 

/dev/hdc1             1.9G  473M  1.4G  24% /sysroot

 

Do I need to do a umount now?

 

Is it umount /dev/hdc1 or umount /sysroot

 

And then do I just hold down the power button on the unit to reboot?

 

Thanks for all your help.  My fingers are crossed this will work 🙂

Not sure if you need the umount, but it would be umount /sysroot

 

shutdown -h -now should do a clean shutdown, then you can power up as usual.

Re: Issues with NV+

So that fixed Frontview after doing another firmware reinstall, but I still can't access my shares.  I'm getting a username/pw prompt.  Looks like it wants to use my local pc as the domain.

 

On my Mac, i used to just connect as guest, but that isn't working... I'd imagine there is something I'm missing something in the setup, just not sure what.

Re: Issues with NV+

I removed the password from each of my shares and I was able to connect.  Not sure what the username was, but it must have been cached on my systems or something.  Oh well, I think everything is back to normal now.  Thanks so much for your help... Time to get a bigger external drive so I can back up my "unimportant" data just in case.

Perhaps you are using "share" security?  That was deprecated a while ago, now the recommended mode is "user" security.  There is some advice on migrating here: http://readynas.sphardy.com/2010/09/how-to-migrate-to-user-security-mode_4917.html

 

Though if you just have it fully open it shouldn't matter.
