I went Oopps. That array is using 0.90 metadata which can only handle up to 2TB devices. The 'resize' code should catch that you are asking the impossible, but it doesn't it seems. You need to simply recreate the array as 1.0. i.e. mdadm -S /dev/md5 mdadm -C /dev/md5 --metadata 1.0 -l1 -n2 --assume-clean Then all should be happiness. > > Problem 2: Can't start array > ==================== > Whatever I do, I can't start md4: > mdadm /dev/md4 --assemble > mdadm: /dev/md4 is already in use. > > /proc/mdadm: > md4 : inactive sdc1[0](S) > 58591232 blocks super 1.2 What do you get if you: mdadm -S /dev/md4 mdadm -A /dev/md4 /dev/sdc1 /dev/sdd1 --verbose ??
