Weird Problems
ReadyNAs pro 4 with latest firmware and 4x 3TB drives. When i login to the admin console and click "shares", nothing shows there not even the default shares. If i use SSH to connect to the NAS, putty...
So it looks like the root filesystem is full:
#df /
Filesystem 1K-blocks Used Available Use% Mounted on
- 4176564 4176564 0 100% /
How can i find what is taking up the space?
By using the du command.
e.g.
# du -csh /var/*
# du -csh /var/log/*
Note the df commands I provided in my previous post were to check for two different ways that the 4GB root partition may be full. Almost always it would be full one way, but not the other. There would be a different approach that would need to be taken if all the inodes were used up.
Thanks for your help! I found what was taking up the space. It was tmp. So i deleted some of the tmp files and restarted the NAS. Now, i can't connect via ssh (get connection refused). Not sure how to even get to it now without SSH. Is there a console that i can connect through?
Freeing up space is only the first step.
What was filling up /tmp ? Crashplan?
With your 4GB root partition full it's likely some config was corrupted.
There is tech support mode (a boot menu option). The credentials for logging into that using telnet are freely available on the web, but using that would have the same implications as using SSH.
It's likely your /etc/default/services file on the 4GB root partition is corrupt.You could copy the default one from /etc/default/config/etc/default/services and add the lines
APACHESSL=1
SSH=1Other config files may be corrupt too e.g. /etc/network/interfaces
Thanks! I have put the NAS into tech support mode and copied the services file to the suggested location. When i looked at the services file located in /etc/default/services, nothing was in the file. If i looked at the default services file located in /etc/default/config/etc/default/services, it had text in it. So if i look at the interfaces file located in /etc/network, it DOES have the correct info in it. Should i reboot the NAS and see if SSH works now? I also started the RAID and mounted the "Data" drive.
Oh i realized i did not answer your question: about what was filling the tmp folder, we use a off-site backup software called Syncrify. This software stores its tmp and merge files in the tmp folder. I have since redirected the Syncrify storage location to a different section of the drive.
