BTW: how can I recover the Information on a mirrored device? config-file: drive 1 device /dev/da1h drive 2 device /dev/da2h volume foo plex org concat sd size 12g drive 1 plex org concat sd size 12g drive 2 considering the volume foo is mounted on /mnt/foo I've done the following: #cp myfile /mnt/foo #ls /mnt/foo myfile Now I "simulate" a drive failure, e.g. halt the sytem, power-down, PULL OUT THE POWER PLUG OF ONE DRIVE, power-up Vinum reports that it is missing one drive, but it seems to be happy #ls /mnt/foo myfile #cp yourfile /mnt/foo #ls /mnt/foo myfile yourfile Look's like it's working with only one drive, really great stuff! Then i simulate backwards, putting the power plug in the drive (yes, I've halted the system before) and reboot. #ls /mnt/foo myfile hmmm......, reading the documentation....., nothing mentioned, is there anyone out there who has some knowledge of these things?
