Updating plugins fail after server runs for a few days

[tonyhamm]

I am having trouble updating plug-ins (any plug in) after the server has run for a few days.  I get error such as " Unable to install as gzip is not available on this system."  I can see that gzip is installed and should be in the path

root@Tower:~# which gzip
/usr/bin/gzip

If I reboot the server, plug ins will install fine......until the server has a few days uptime.

 

It is frustrating that everything else seems to be running fine in UnRaid but having to restart fairly regularly to install upgraded plugins is getting old.

 

Any ideas??

Try booting with stock go file and see if you still have problems

I haven't tried your suggestion yet, but I don't see how, if it was go file, things would work fine when rebooted and then fail days later.

What do you get from command line with this?

df -h

I found the problem!!  I had a bash script that was scheduled to run every other day that, as part of the script, was incorrectly redirecting the output of a command to /dev/null.  Because it was not doing the redirection of stdout and stderr it was overwriting the character device /dev/null with a regular file called /dev/null.

 

Anytime something was trying to redirect to /dev/null it was failing.

 

I have

• removed the incorrect /dev/null file 
• created a new character device named /dev/null
• and finally corrected the redirection to 

rm -rf *.1 > /dev/null 2>&1

instead of 

rm -rf *.1 2>&1 /dev/null

 

Since making this change to script and running manually the permissions on /dev/null are staying

root@Tower:/dev# ll null
crw-rw-rw- 1 root 1, 3 Nov  2 14:59 null
