[rancid] Can't update router.db

Tue Sep 26 14:34:16 UTC 2017

Hi Dan,

Run the command “ps  aux”.  you’ll probably find rancid being stuck on some device or another.  You can log in to that device and kill the telnet/ssh session from there, or you can kill the ssh session on the Linux CLI (kill -9- <pid>).

Looks like there is only one group and the permissions look correct to me.

[root at observium /]# cd /var/rancid/
[root at observium rancid]# ls
logs  observium  SVN
[root at observium rancid]# cd logs
[root at observium logs]# ls
[root at observium logs]# cd ..
[root at observium rancid]# cd observium/
[root at observium observium]# ls

[root at observium observium]# ls -l

-rw-r-----. 1 rancid rancid 1718 Sep 22 11:25 routers.up
[root at observium observium]#

It doesn't work at all anymore.  I found this at the end of the logs:

rancid observium hung on observium.gvsd.ca<http://observium.gvsd.ca>?  Old lockfile still exists:
-rw-r-----. 1 rancid rancid 0 Sep 22 11:25 /tmp/.observium.run.lock

there is only one thing that requires that lib and it is an example
script; if you are not using rtrfilter, you can force that installation.

While rancid-run can take a rancid group as an argument, the groups normally
come from LIST_OF_GROUPS in rancid.conf.

I am more suspicious that you have more than one rancid group
(/var/rancid/<groupname>) and you've updated one but not another with the
same devices.  another possibility is that permissions are incorrect on
files/directories in the rancid group's directory, presumably:
        chown -R rancid /var/rancid

Also, look at the rancid logs for given group.
