Hi,
Just wondering what the best recipe for migrating a user’s home
directory content from one GFPS file system to another which hosts a
larger research GPFS file system? I’m currently using rsync and it
has maxed out the client system’s IB interface.
Be careful with rsync, it resets all your atimes which screws up any
hope of doing ILM or HSM.
My personal favourite is to do something along the lines of
dsmc restore /gpfs/<username>
Minimal impact on the user facing services, and seems to preserve atimes
last time I checked. Sure it tanks your backup server a bit, but that is
not user facing. What do users care if the backup takes longer than normal.
Of course this presumes you have a backup :-)
JAB.
