Getting somewhere... used: mdadm --assemble --run /dev/md0 --uuid=.... specifying the uuid rather than the device brought it up as expected with 1 of the 2 drives in the array. However, when trying to mount it: mkdir /mnt/test mount /dev/md0 /mnt/test I get a "mount: No such file or directory" Should mount after it's started, right? Cheers, James.
