The backups for the CA Agile Central On-Premises appliance are failing.

Looking at the /home/appuser/rally_backup.log file shows the following entry:

Environment

Release:
Component: ACPREM

Cause

This can occur if the /dev/null device file has become corrupted or if access to /dev has been restricted.

Perform the following actions to troubleshoot /dev and /dev/null:
Check the contents of /dev/null
cat /dev/null 
It should be empty, but if it returns data it could be an indication that someone or something copied a file in place of /dev/null instead of piping data out to /dev/null 

Verify /dev/null file properties
ls -l /dev/null 
Output should be as follows: 
crw-rw-rw- 1 root root 1, 3 Apr 18 01:34 /dev/null 

Verify /dev permissions
ls -dl dev
Output should be as follows:
drwxr-xr-x 19 root root 3180 Aug 23 10:26 dev

Resolution

There are two potential solutions to fix /dev/null:
  • Reboot the system. The /dev/null file will be recreated during startup 
  • Execute the following command: 



rm -f /dev/null; mknod -m 666 /dev/null c 1 3




 


If the permissions on /dev are incorrect, run the following commands:



chmod a+x /dev
chmod a+r /dev
