I don't understand the forget command. I saw this in comments section of Ralf's web page about gmirror: -------- If a drive fails (eg. drive /dev/ad4): # gmirror forget gm0 # shutdown -h replace the drive with a fresh one # gmirror insert gm0 /dev/ad4 And it should start synchronizing if autosynchronization is turned on. -------- Why do you forget gm0? I would think if ad4 failed I'd "forget /dev/ad4". would really appreciate a brief explanation. thanks! Royce
