[Bdi4emc-help] hard drive crash

Tue May 13 17:27:09 CEST 2008

   thank you.
   fyi, this is a recap of how it turned out, to my recollection.
   we took a power hit.  video quit.  changed to onboard video.  machine
   failed to boot, but had video.  switched back to video card.  no
   video.  took video card out reseated it.   then the card worked, but
   fsck seemed to "get stuck" forever.  i tried rebooting a few times
   with the same result.  so i figured the disk was bad or i would at
   least need to reload the os.
   i really wanted to recover my configuration files and my home
   directory so i put the disk into a different machine and did the fsck
   on it.  this however went smoothly so i decided to try the drive
   again, in the mill.  what do you know,  i have bdi-4.51 running
   again.   it hasn't caused any trouble since, so i will leave well
   enough alone.
   of course, none of this makes sense.  following the video card events
   perhaps reseating the hard drive did the trick???
   but, i will save your email for the inevitable future.

i was running bdi 4.51 but had a hard drive crash.   fsck seems to have
endless errors.  so looks like i have to reload the os.  the mill was
doing everything i need it to so it makes sense just to return it that
configuration and avoid any experimentation.  but i am wondering if i
can run emc under a recent release of ubuntu rather than load bdi4emc
onto a new disk.

You can use just about any distribution to run EMC - I used to use Red Hat 
then another RPM based distro before some real nasty upgrade issues bit hard. 
As long as you have a 2.6.xx series realtime kernel (using the RTAI patches) 
installed, there shouldn't be any major problem. You will need to compile 
from the sources (which can be found on the CD) to ensure correct linkage to 
the installed libraries, kernel, and RTAI versions.
