Nagios Support Forum

Hi,

Trying to upgrade to the latest version of Nagios XI and keep receiving the error message "mysqldump: Got errno 28 on write
Error backing up MySQL database 'nagios' - check the password in this script!"

From what I can gather, its not a password/script issue, its a problem saving the MySQL backup?
Running df- h tells me that nothing is short of space, although I'm not sure which filesystem would be the one its trying to save to. Maybe the DB is too big to be saved - how can I tell?

Thanks,

True... My DB must be pretty big then...
