If a disk dies, you swap in an RMA, and rebuild the mirror. If "swap in the RMA" involves downtime, then gmirror will see the new disk at boot and DTRT. Or have you seen too many horror stories on the mailing lists? Currently, I have a whole bunch of systems with one-off 3ware or Adaptec controllers, and I don't know how to monitor them reliably. I tried doing a 3ware a month or two back, and there was this crazy race between how old the binary versus the kernel module versus the firmware was and I just gave up. Grr! As RAID1 solutions go, gmirror take a lot of the headache out of administration. IMO, YMMV, and I have daily backups ... -- http://dannyman.toldme.com/
