Nagios Support Forum

Hello,

This morning, I logged into NagiosXI on the web interface and received the following error:

DB Connect Error [nagiosxi]: Database connection failed.

I did a search through the forum and found this thread:

http://support.nagios.com/forum/viewtop ... ror#p25583

I looked through the solution however when I tried to issue the first command in that thread I get an error at the CLI of Nagios.
Command = psql nagiosxi nagiosxi -c 'vacuum;'
Error =
sd 0:0:0:0: rejecting I/O to offline device
sd 0:0:0:0: rejecting I/O to offline device
-bash: /usr/bin/psql: Input/output error

Then even without any commands being entered I continually receive this error:

sd 0:0:0:0: rejecting I/O to offline device
sd 0:0:0:0: rejecting I/O to offline device
sd 0:0:0:0: rejecting I/O to offline device

I'm not a Linux expert, but it looks like the primary drive is unmounted?

With all the strange issues I've been having, it looks like this image or install of nagios might be a lemon.

Any help would be appreciated....

Thanks,

Can you post the output from:

mguthrie,

Unfortunately the system (linux) won't even let me issue this command without throwing me an error.


sd 0:0:0:0: rejecting I/O to offline device
sd 0:0:0:0: rejecting I/O to offline device
-bash: /usr/bin/psql: Input/output error


Same as before.

Would you suggest I restart this system?

FYI:
- Running on a Hyper-V Server
- Latest Nagios (Virtual PC vhd image) with Updates

Most definitely yes : )

Hi mguthrie,

Seems like after a HARD RESET, the system started working again.

I ran the repairmysql for nagios and nagiosql just to repair any corrupt portions of the DB.

Hopefully this doesn't happen again.

Any suggestions beyond this?

This seems like for some reason your VM wasn't able to connect to it's storage on the Hyper-V Server server.. At the very least it is strange.

Sounds like you did the necessary steps for the database.

Only thing I would add is if you have any other similar issues, I would look at possible problems with the Hyper-V Server's storage.

Also, while you have it running it would be prudent to make a backup of your XI install and move it offsite in case another problem arises
