MariaDB [(none)]>

I see you have Percona XtraDB installed. Is that db clustering software? Is this db part of a cluster?

I don't know what Percona XtrDB is.

There was some thought of making this DB part of a cluster but it was NOT done.

There is no cluster.

That must have been left over from when it was under consideration.

Tom

Hey Tom

1. log in to mysql please send me the output of that

2.from command line: log in to mysql: you can repeat the above for any tables giving you trouble

3. in your mariadb.log I see: It would be great if you can uninstall it, as it would remove an unknown variable to solving your db issues.

Let me know how things go.

Thanks

Here are the results you requested.

I am removing the Percona stuff.

[[email protected]@nagiosxidb ~]$

There are now values in the nagios:servicechecks table.

I think they started populating after I did the table rebuild command.

The have not been any entries in that table until now.

I may have to truncate the nagios.log file to recover some disk space.

Thanks for your help.

Tom

Hi

Yeah, it went from 0 rows to 37813 rows.

I'm glad things are working for you now.

Take care.
