Note flashing red light on failed drive I've had those buzzers fail and my logs are the only indication. I've had network equipment that has the dual red/green LEDs. I'm red/green colorblind (like 15% of the male population) and cannot see the difference if it's a light shade of green/red. Also, my server rooms tend to be a in a closet, across a hallway or building, several floors away with no one entering them for days at a time. There's nothing wrong with the buzzers, but if you're not there to hear them, they don't matter. Logs or other monitoring systems can reach me when I'm not in the room. They can survive failures when they're on a separate system (email from logwatch, syslog server, etc) Yank drive and pop in new one
Go back to playing Starcraft
I wish ;-p ;-)
> * shutdown the system when the drive arrives Ewwww. I thought you could do hotswap with Linux software RAID?
It depends. SATA hardware is hotswap by spec. Does the driver? I know Solaris 10u3 doesn't hotswap SATA. Standard IDE hardware doesn't hotswap. Older SCSI isn't hotswap but you could get away with it if the fuse didn't blow.
