Another thing .......
Your pre-migrate percent is too high at 80%. I don't
imagine that this would cause the problems that you
are having right now. But, if you've got
high threshold=30
low threshold=10
pre-migrate %=80
that means that when the system is at 30% utilized, it
will kick off an automigrate, migrate your system down
until it is 10% utilized, then pre-migrate (which
writes the files to the space management pool, but
leaves them on your system) another 80% ??. You don't
have another 80% to migrate. At most your pre-migrate
percent can be 10, which would premigrate everything
else left on the disk.
I personally think your high and low thresholds are a
low. Of course, I don't know how fast your system
grows, but somewhere in the 75% high down to 50% low
seems more reasonable. Just my 2 cents worth though.
