[lustre-discuss] How to remove a pool

Hi all,
once upon a time i created a pool to restrict files to a subset of OSTs:

pool_add scratch.one-third scratch-OST[0-30/3]
lfs setstripe /scratch --pool scratch.one-third

Now i want to remove that restriction for all new files, so that
all new files are distributed about all OSTs.

How to do this?

Should i ...

... "pool_remove" OSTs from the pool and "pool_destroy" the pool or 

... should i create a new pool with "scratch-OST[0-30]" and setstripe
all existing directories recursively with that new pool

... or is there a way to un-setstripe directories from pools?

Mit freundlichen Grüßen
Bernd Melchers
