OH DEAR, yes.  Human error, mount the same san disk on two systems at
different times (1 week apart) and see what happens.  Newfs does
wonderful things!!

            I'm sorry, but I have not had similar experience.  Most SAN
installs that I've worked on have mirrored disk, dual or better
interface cards as well as cabling so that there isn't just one path to
the drives.  I have tried NAS setups that have failed badly, but
thankfully those were in a testing mode.  Never trust a sales droid,
always push the "press-to-test" button. 

 


The SAN's I have experience with have all that - dual HBA's, multipath,.
etc. 

They are still subject to failure and human error.

As usual, human error is the biggie.
