USB drive as third drive in a mirror

P

Hi,

I have a server with two internal hard drives running as a ZFS mirror. To have an external backup I have the idea to add a 3rd third drive to the mirror which is an external USB drive. The plan is to connect the drive from time to time. Once the external drive is resilvered I like to disconnect the drive again. Is there anything special I should consider? Can I just connect/disconnect the USB disk or do I need any special command to start resilvering?

Thanks,
Peter
