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?
