I am testing a machine with two SATA drives in startech.com removable
caddies. Everything including swap is RAID1. (I'm running x86_64
Scientific Linux 4.2, a RedHat enterprise clone.)

Informal tests suggest that pulling out an active disk causes the whole
machine to hang up but removing a disk from the RAID arrays and pulling
it out gives the message: "nv_sata: Primary device removed" and
everything happily keeps running.

Is this a fair description? In practise do people find that following
the above allows a failed disk to be replaced without shutting down the
machine? 

Thanks

John
