Strange Warning: Less than 5% of volume media's capacity is free.
I got a strange Warning ofrom my RN102 after upgrading to ReadyNAS 6.6.1. "Volume: Less than 5% of volume media's capacity is free." When I browse the sytem via the Web interface I see that I...
On another thread, Netgear said they'd be starting a 6.7.0 beta very soon to roll out AV fixes.
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:
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.
Can anyone help please?

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
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).
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:
I'll keep an eye on it to see if if uses significantly more over time.
Thanks again,
Paul
The Volume has now synced and I have actvated the AntiVirus. Linux-dash now shows:
Filesystem Size Used Avail Use% Mounted
/dev/md0 3.7G 620M 2.9G 18% / I'll keep an eye on it to see if it fills up significantly over time.

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.

I think I found the problem. It always happens after or during the Virusscan definition updates. This is my latest log with the warning.
I hope NETGEAR looks in to this urgently.
