Remove problems triggered by items not supported anymore by the agent

[ohmer]

Hello,

I have a trigger for low disk usage with a filesystem discovery. One server had a external hard drive connected that was almost full. So zabbix triggered a problem. The disk has been removed, but this problem still trigger. I have a question mark that say "Not supported by zabbix agent" (yeah of couse, the hard drive is not connected).

How can I remove problems triggered by items that are not supported anymore?

I assume that the Items/Triggers was created by Discovery Mounted Filesystem process.

After the external HDD was disconnected, LLD didn't discover it anymore and had to delete it (Items and Triggers and Graphs) (after the period of "Keep lost resources period (in days)"

I changed the default value of 30 days to 3 days. My items are inactive since a week but they are still showing. Is it because it was set to 30 days when they were created?
