I got a serious problem, my zabbix database grew to much, using all the partition /u01 on the server, causing the postgre and zabbix server to stop.
Later I truncate the history_text table and got my zabbix server back.
The issue is, every time that I open a graph on lastest data, it appers the error message bellow. (yes, I have no database backup ).
And at last, sometimes my dashboard show a lot of alerts, all about the machines agent.ping issue.
Is there a way to fix this error?
