Thank you for this! Works just fine!
EDIT: It only seems to work. When I set the pattern, the warning go away for a while. But then it come back, ignoring the pattern.
By the hint text, it seems that applying a pattern will delete the matching disk monitors (thus "fixing" the issues), but after a while the monitors are back on. Probably because the agent is still sending data about the disks.
To me, this seems like a implementation bug. Could someone confirm?
