RN214 Failing to Update Antivirus
Hi, For the past week I have been getting a daily alert "System: Antivirus scanner definition file update failed due to download failure. Check your Internet connection." I have found a number of o...

So far as I am aware, there have been no recent changes, (updates etc), that co-incide with the start of this problem for me.
Other posters have said this too. One has been able to update using ssh - so that is one option if you are comfortable with linux. I don't use the AV service on the NAS myself, but I did see something similar a couple years ago. I think the issue back then was on the ClamAV end (one of their update servers wasn't working right).

~50% utilization of the OS partition isn't enough to cause your problem, but it is higher than normal. The OS partition of my own RN202 is about 16% full at the moment. Plex is the only app installed. I don't use AntiVirus (if I did, my OS partition would be somewhat more full, but not 50%).
If the OS partition gets completely full, the NAS will misbehave in a variety of ways (including corruption of the NAS configuration files). 50% isn't dangerously full, but still worth paying attention to.
Likely one of your apps (not Kernel Plus) is using the space. The simplest way to bring it back down is to move some of the folders to the data volume (generally into the hidden .apps folder), and replace the original folders with a symbolic link to the new location. This requires ssh (and some knowledge of linux).
Maybe also check if you are running Transmission or Transmission NT. If you are using the older Transmission, you might want consider switching to Transmission NT and see if that reduces the OS space.
If you don't have the linux skills to troubleshoot (and move folders around), then I suggest periodically downloading the log zip file, and making sure that the OS partition fullness doesn't increase over time. Not sure if linux-dash will give you this info or not (as that also isn't an app I use).
Hi,
Thanks for your detailed reply. Whilst I do use Linux as my desktop OS, I am not confident enough with it to start moving folders around - I know how to move them, but not necessarily what to do if it goes wrong.
What I don't understand is that each day, shortly after receiving the daily error email, I can SSH into the ReadyNAS, type "freshclam", the update downloads and installs, and is seen by the NAS' overview screen and logs and everything is OK - until the next day, when the same issue repeats? Is this not an issue with the way the OS is trying to do the update>
As per your sussestion, I have stopped and removed "Transmission for Readynas" v3.00.8, by Poussin and replaced it with "Transmission NT" v2.92-nt2 by NAStools. The md0 parition is still showing 49% used, and was also the same when neither app was installed.
A partion only 50% full causing issues seems very low to me - is that to be expected?

As I tried to say above, I don't think the 50% fullness is causing your AV problem. If it stays at about 50%, it shouldn't cause any problem at all. But if the space is growing, it will create other problems when it gets full. The OS partition is only 4 GB, so you do need to be careful on what you put there.
Shifting stuff is fairly easy - you copy the folder with the appropriate cp command, and then replace the folder with a link using ln. You can play with this on your desktop first, to make sure you have the commands down.
And if you simply check with du, you should be able to find out what apps are using up the space.

Others have also reported that freshclam works. I am wondering if the NAS is looking for an update to the software, and not just a new virus definition. You might try looking through the logs for more details on what is going wrong.
Thanks again for your assistance, but I do not understand how to use the information that you are giving me. "cp" to copy a file to a new location I am fine with, but how exactly do I use "ln" to create a link? (I have never done that before). Also, if I SSH into the NAS as root and type "du" I get back:
12 ./.ssh
36 .
What is this telling me, or am I using the command incorrectly? (I also tried "cd" to /dev/md0/ and again "du" gave me the same response.
If the available space in the md0 partition is not the real issue, and given that I can daily manually update the AV by using "freshclam", is it possible to automate that process with some sort of script? If so, how would I do that? I am vaguely aware of cron jobs (?), but do not know how to create one for a task such as this.

Once again, the daily AV update has failed - and once again logging in and manually "freshclam" has temporarily resolved the issue. Can this daily "freshclam" task be automated seperately from the OS task that always fails?
