[ExeterLUG] pi cluster image errors

[Malcolm Dinsmore]

Hi Paul,  

Glad you got it sorted... maybe just needed to reset the device file system interface,  which sometimes gets confused especially if the file system was mounted when dd is performed. 

I don't think I said in the notes I created a user called 'mpi' with password 'mpi'.  I know over the top security precautions gone mad! This user has the path etc set up to run the test programs.

I plan to bring a Ubuntu / win8 laptop with a couple of card readers on Friday and a screen keyboard etc for the master node (other nodes don't need screen etc). I've also got half a dozen net cables.  Will have a think of anything else we might need. 

Malcolm

Ok further to this,  removing the card. and reinserting it, so it mounts
again seems to mount it fine,  giving me 2 partitions /boot and /arch
and files within.

Which brings me to the question why was it having issues in the first place
