Having a go at building a raid5 array using the new imsm support and having good luck keeping drives in the array, etc. Nice work. I have a few questions though as I am having some trouble figuring out how to properly start this container. # mdadm --version mdadm - v3.1.2 - 10th March 2010 # mdadm -Es ARRAY metadata=imsm UUID=30223250:76fd248b:50280919:0836b7f0 ARRAY /dev/md/Volume0 container=30223250:76fd248b:50280919:0836b7f0 member=0 UUID=8a4ae452:da1e7832:70ecf895:eb58229c # ls -l /dev/md/ total 0 lrwxrwxrwx 1 root root 6 Mar 22 20:54 0 -> ../md0 lrwxrwxrwx 1 root root 8 Mar 22 20:54 127 -> ../md127 lrwxrwxrwx 1 root root 8 Mar 22 20:54 Volume0_0 -> ../md127 As you can see, the name for the link in /dev/md does not agree with the name that the Examine is coming up with. Is it better to just forgo the ARRAY statements and go with an AUTO +imsm? And last, does the concept of a write-intent bitmap make sense on an imsm container? If so, I get a segv if trying to run mdadm /dev/mdX -Gb internal on either device.
