Comment 4 for bug 316670

I have just noticed that <code>blkid</code> does not mention the UUID of my dodgy /dev/md3 device. Three other functioning /dev/md devices are shown fine.

<code>vol_id</code> produces normal output, stating the UUID, but this doesn't feature in the blkid output.

I notice also that <code>mdadm --detail /dev/md3</code> shows the the array is local to this host, whereas the other arrays do not have this flag. I have been forced to recreate the array every reboot, so this is perhaps not significant. N.b. I am only booting into one system, not trying to mount the arrays from different OSes.
