Re: Strange Warning: Less than 5% of volume media's capacity is free.
Others have reported the NAS incorrectly reporting a problem with a share when it's the OS partition that's almost full, and that sounds like your problem. There are several things that can cause it. But you need to check before it gets completely full and you are unable to access Frontview.
Currently, the only way to check/fix a filling OS partition is via SSH (and tech support mode, I thnk) and some knowlege of Unix or specific directions. I have put in a suggestion that better tools be provided for preventing and fixing this issue. There are a number of existing message chains on this subject.
Re: Strange Warning: Less than 5% of volume media's capacity is free.
I am getting this warning regularly for the past couple of days on my RN214: "System volume root's usage is 95%. This condition should not occur in normal conditions. Contact technical support." Is this the same thing? ( I am also getting the less than 5% free warning).
I was getting it on OS v6.6.0 and after upgrading to v6.6.1
I have linux-dash installed and I see this:
Disk Usage
Filesystem Size Used Avail Use% Mounted
/dev/md0

I can see that it is /dev/md0 that is reporting to be full, what can I do about it? I am OK with SSHing and Linux command line, but I don't know what commands I need to use.
Re: Strange Warning: Less than 5% of volume media's capacity is free.
You can use du to locate where the space is used. This situation (full root) can occur for different reasons, most common ones are applications installed from backend (like mysql or crashplan), log files that aren't rotated (added by apps), etc.
1. cd into the path you want to analyze first
2. du tells you where the space is used
3. cd into biggest folder
4. du
5. Repeat until you find the folder containing the files, then use ls
# cd /
# du -d1 -hx .
-> var is the biggest
# cd var
# du -d1 -hx .
-> log is the biggest
# cd log
# du -d1 -hx .
-> current folder only is big
# ls -alh
Re: Strange Warning: Less than 5% of volume media's capacity is free.
The step by step approach is interesting to analyze the filesystem usage. But there are shortcuts available, like this one:
du -hx / | sort -hr | head -n 10
If the first line doesn't show 4GB, then there might some data in a folder that is not readible using du (for example, /data, but not on the data volume, on the OS volume ; data that was created under the mountpoint path before the other volume was mounted).
Re: Strange Warning: Less than 5% of volume media's capacity is free.
Thanks for reply.
I found that Logitech Media Server was one of the largest folders at around 450MB, ClamAV was only slightly smaller (IIRC). I have been using the Super-Poussin version of LMS since the problems that happened when the OS was upgraded to 6.6.0 and I saw on another thread that this could have been causing a problem since it writes a lot of data to root (?). I tried uninstalling it and manually removing the associated folders that I could find, but only managed to get /dev/md0 down to 94% used. Uninstalling all of my remaining apps had no effect on this, so I decided that the only way I was going to be able to completely clear it out was a full factory reset and rebuild, (luckily I had updated my backup the day before!). The Volume is still resyncing, but I have re-installed LMS, (NAStools version from the repository this time), DVBLink, linux-dash and Transmission. I will activate the Anti-Virus after the volumes have re-synced as it seems to slow it down a lot.
Linux-dash is now showing:
Disk Usage
Filesystem Size Used Avail Use% Mounted
/dev/md0
3.7G
484M
3.0G
14%
/
I'll keep an eye on it to see if if uses significantly more over time.
Re: Strange Warning: Less than 5% of volume media's capacity is free.
Dear HyacintheJ:
I have started this thread. I checked my system following your instructions after rebooting my system once again (after 6.6.1 upgrade). I see now that everything is normal. I have 75% free space.
However, my system log contains two warning messages (right after the OS upgrade); one indicating 30% free space left and second indicating only 5% free space left.
I had installed or removed no application. I deleted from or added to no file to the OS partition. You may like to check the upgrade procedure. It may have created and not deleted properly tempoarary files until the second reboot somehow. I hope you find this inorfmation useful. Thank you again for your continued help, all Netgear folks.
However, my system log contains two warning messages (right after the OS upgrade); one indicating 30% free space left and second indicating only 5% free space left.
Are you seeing any warnings about the system or root volume in the log?

No, I do not see any warnings at all since the incident and the warnings I got seem tnot to be about the system or root volume.
I am copying the segment of the relevant log FYI:

Issue was fixed last night 18jan2017. This evening I've received some notifications from my RN202 that a virus was found:
System: Antivirus scanner found a threat (Eicar-Test-Signature) in the file ....... (several times)
The Eicar-Test-Virus was part of some documentation.
At the same time this issues started:

OTHER VIRUS FOUND....
I have the feeling that the NEW Anti Virus concept introduced with Firmware 6.6.1 is causing this behaviour when ClamAV kicks in. Just guessing....
Re: Strange Warning: Less than 5% of volume media's capacity is free.
Now that the AntiVirus extra features is no longer a stand alone app but part of the OS, how does one access the AV to do things like a virus scan etc. (Although I had AV activated previously, I never installed the extra app).
Re: Strange Warning: Less than 5% of volume media's capacity is free.
Hi ikonuk
Based on the description of the issue that you have provided, I may need to check this with others who can probably assist you and get back to you as soon as possible.
Re: Strange Warning: Less than 5% of volume media's capacity is free.
Dear FramerV:
Thank you very much. I am glad I could be helpful.
I checked my logs again. Indeed, since the 6.6.1 OS upgrade, everytime virusscan definition is updated I have a "low Volume Media" message. No problem after that until the next definition update.
By the way, I have a very plain vanilla system with no applications installed and no major modifications on the system or the default options (few exceptions like disk spin down etc which should normally not effect the OS).
I am looking forward to working with NETGEAR to isolate and resolve the source of the problem.
Re: Strange Warning: Less than 5% of volume media's capacity is free.
Hi, having yellow codes come up with low media capacity. Todays codes pasted below. Helpful information is that system is updated to 6.6.1 and perform USB backups to 2T Toshiba drive. You can see that antivirus has been updated recently. I'm having difficulty getting scans from our network printer/copier/scanner. Is this related to the low media capacity errors? How can I fix it?

Re: Strange Warning: Less than 5% of volume media's capacity is free.
Is the volume actually over 90% full?
If not: There's some indication from other posters that suggests the new AV might be misbehaving. You might try turning it off for a day and see if the system behaves better.
Re: Strange Warning: Less than 5% of volume media's capacity is free.
Hi Steve, just under 2.38 TB available. I can try shutting the system down overnight tonight. However, I have unplugged it and replugged it in this morning...still got the low media capacity codes.

StephenB:
I have received two definition updates (one yesterday and one this morning), so far so good. NETGEAR may have resolved the issue. Let us wait few days and see.
Re: Strange Warning: Less than 5% of volume media's capacity is free.
After doing some research I found the following:
- The problem described in post#1 occurs only (at least for me) when clamav finds a virus (also a test virus)
- clamav is then creating some files within the /tmp folder
- /tmp should be excluded from scanning according /etc/clamav/clamd.conf, but it seems to fail for recursive directories according 'clamav.conf' man page.
Conclusion. NetGear kindly should review the clamav configuration files and the scanning behaviour.
