StephenB (Guru) :
I have Putty on my computer and can use SSH to address issues. Can you walk through the specific steps to address and fix the issues or provide links to other dicussions that outline how to fix the issues?
Much appreciated
The first step is to ssh into the NAS, and look at how full the OS partition is.
# cd //
# df . -h
# df . -i
The assumes that you've enabled ssh in the NAS (installed the EnableRootSSH add on for your plaform). If you haven't already done that, the install might fail, since it does require some space on the OS partition. As a reminder, you log in as root, using the NAS admin password.
Normally the OS partition is about 20% full.
StephenB,
Indeed, as suspected the OS volume is completely full. The issue appears to be the 1.74 GB ReadyNAS_Remote.log file generated on Sep 18. Below is the OS file space use and the large log file:
Large log fileOS spaceIs there anything important in the log file? Is there a way I can copy it to an external USB thumb drive or the main partition?
SSH commands would be greatly appreciated as I am an SSH novice. Thanks.
Can I simply delete it and re-boot the nas?
Once the NAS is re-booted, should I then be able to update the firmware without an issue? Let me know if there is anything else that needs to be done first.
You can just delete it or truncate, and then reboot the NAS.
You can delete it using the rm command
# rm ReadyNAS_Remote.log
You can alternatively truncate the file to 0 bytes using
# echo " " >ReadyNAS_Remote.log
Either way, the file system is case-sensitve, so you do need to pay attention to the capitalization.
After it boots, you should disable ReadyNAS Remote. It's been replaced by ReadyCloud, which isn't compatable with your NAS.
I have removed the ReadyNAS Remote file and was then able to reboot the NAS successfully.
I upgraded the firmware to 4.1.15 and it appears to be running stable and without issues for the time being.
I checked in Frontview and ReadyNAS Remote is NOT enabled (refer to photo below), so I am not sure why it generated the huge file that filled up my OS.
ReadyNAS RemoteAnyways, now that things appear to be working properly, is there any reason to upgrade again the firmware to 4.1.16? Is there a significant difference between the firmware versions or vulnerability that needs to be addressed?
Also, how do I change the root access password? It was default set to my admin password, and I would like to change it to something else.
