[GE users] binary re-location

Hello List

Possibly this solution will work for you.  I have written it in
commands to provide precision.

Assumes SGE_ROOT is /opt/sge and SGE_CELL is default, and
that SGE the above are located on filer:/export/opt/sge/default

     cd /opt
     mkdir sge.local
     rsync -ruvalP --exclude default sge/ sge.local/     #< copy
     qconf -km                 #< kills the master
     umount /opt/sge       #< maybe will have to kill local execd, dbwriter, other stuff before this
     mv sge sge.save       #< move the old mountpoint out of the say (should be empty anyway)
     mv sge.local sge       #< move the new 
     rm -rf sge/default     #< remove the local copy of the spool, should be not there but just to be sure
     mount filer:/export/opt/sge/default /opt/sge/default   # < mount just the cell
     /etc/init.d/sgeqmaster start  # < start SGE

Surely there are some other details for your setup, but thats the gist of it.

First thing -- you will need to shutdown the qmaster during the
directory path migration, but doing so will not affect the running and
pending jobs.

Secondly, will you adjust the mount points so that the path names are
the same before and after the transition?? Otherwise, you will need to
adjust the bootstrap file:


Finally, you will need to adjust the "settings.[c]sh" scripts and/or
startup scripts.

As long as you don't delete or damage the spool directory, then your
jobs won't be lost -- which means "at most" you will cost extra

And I always suggest this quick and dirty hack -- if you move the
spool directory, you can create a symbolic link from the original
directory to the new one, and to SGE the path/location stays the same
after the migration.


P.S. I might miss a thing or 2, so test it with your test cluster
first if you can't affort an extra minute of downtime!
