Nagios XI 2014R2.5 Backup failing

I have a hunch it may be due to a Sudo change... (When we upgraded a box to 2.7 the Nagios User didn't have permissions) This box however is still running 2.5 and I'm wondering if that change may have negatively affected the 2.5 box. I'll paste below the change below the error... then again we have another box running 2.5 and working fine :/

Sudo File change, per my Unix admin the way they do Sudo is from a master file. The entry on the Nagios Box doesn't really do anything:

It looks like the mysql database needs to be repaired. Here are the instructions to do that.

After the repair, see if the backup finishes.

Ran the repair which worked. But we're seeing some errors in /var directory:

Is the MYSQL database off loaded to another server?
If it is running locally, lets restart the processes by following these steps.

Code: Select all

service nagios stop
service ndo2db stop
killall -9 nagios
service mysqld restart
service ndo2db start
service nagios start
Try that and see if the errors are gone.

So when I run that MySQL repair things look good for a bit. not sure how long... but after what seemed like 30 minutes now none of my services are listed in NagiosXI or core.

Things seem to be running in the background okay though as we're still alerting.

What it's saying when we try to pull up the services page in XI:
SQL: SQL Error [ndoutils] : Got error 28 from storage engine




Showing 1-500 of 9,885 total records
We are currently running 2500 host checks & close to 10,000 services on the box (it's a massive box hardware isn't being taxed). But wondering if the Engine just isn't keeping up???

Any ideas for diagnosis?

For the record I don't care so much about the back up running at the moment as I do getting the Database error fixed!

Error 28 is related to storage space..

How's a df -h look?

I think this happened last time, there was a deleted file still holding onto file system space.

Gonna reboot the box.

Reboot resolved things for now. Thanks for the heads up... Didn't expect that maint to fill up the /tmp and almost /var

We're going to be migrating off this box soon so we shouldn't have space issues going forward.
