Two usb attached WD myBook 500gb external drives. The first drive is
setup as a gmirror provider, and mounts/functions fine, when I attempt
to add the second external drive it detects but will not rebuild, it
simply remains at 0%, no drive activity.

Following the attempt to rebuild any attempt to stop the providers or
remove the stale drive causes the system to lockup or rather become
almost entirely unresponsive. Responds to pings, moused input works,
existing ssh sessions still function, but cannot login, execute new
commands, or get output without serious delays, sometimes--eventually
the system snaps back and everything is fine but it can take a very
long time. Nothing seems to entice the second provider to sync up.

I have tried setting gmirror to auto rebuild and manual, both yield
the same result. I have also tries each drive as the first provider,
again with the same results either way. Also tried gmirror compiled
in and as a mo

I'm not sure if this is gmirror, usb, or the combo of the two
elements, or maybe even something with the mybook.


An addition, the second provider does rebuild, just extremely slowly,
according to the activity lights moving data only in short bursts
spaced by long periods of inactivity. In the last eight hours the
provider has reached 2%.

thank you
