In which direction will the devices be synchronized, if I create a new RAID-1 array with an external bitmap? Assuming I use this command line: mdadm --create /dev/md11 --level=1 --bitmap=/mnt/src/bitmap --raid-devices 2 /dev/storage/origin /dev/esata/copy Should I expect /dev/storage/origin being written to /dev/esata/copy? Or perhaps, /dev/esata/copy will be written onto /dev/storage/origin? I couldn't find it explained in the fine manual, so perhaps creating an array with a missing device: mdadm --create /dev/md11 --level=1 --bitmap=/mnt/src/bitmap --raid-devices 2 /dev/storage/origin missing and adding a second device later will be safer... -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
