Alerts not triggered by removing a drive.

[killervette]

I dont know if this is a bug or not, im very new to freenas. I have a ZFS Raidz1 with 3 drives. I physically disconnect a sata cable to remove the drive. The freenas webpage does not show any alerts. Viewing the drives in the area shows a drive as "unknown". The terminal screen on the server shows that it lost the ata device.

Is this normal? The array shows as healthy. It took a reboot to show the alert
