Hi all,
thanks a lot for your comments. Agreed, I better avoid it for now. I was
concerned about how GPFS would behave in such case. For production I
will take the safe route, but, just out of curiosity, I'll give it a try
on a couple of test filesystems.
Don't use symlinks there is a range of applications that will break and
you will confuse the hell out of your users as the fact you are not
under /projects/new but /random/new is not hidden.
Besides which if the symlink goes away because /projects goes away then
it is all a bust anyway.
If you are worried about /projects going away then the best plan is to
mount the GPFS file systems somewhere else and then bind mount the
directories into /projects on all the machines where they are mounted.
GPFS is quite happy with this. We bind mount /gpfs/users into /users and
/gpfs/software into /opt/software by default. In the past I have bind
mounted random paths for every user (hundred plus) into /home
JAB.
