Yes, you can add multiple paths for the job. Not sure of the limit,
I've usually not done more than 4 or 5 but it's possible you can
have more.
Impact policy refers to the amount of cluster resources the job will
use. LOW, from my memory is no more than 10% of total cluster
resources, HIGH doesn't have a cap. I haven't been able to find
MEDIUM but, as you could guess, it's somewhere in the middle.
TreeDelete is one of the few jobs that doesn't use LOW as a default
since there are times when you really need to clear up space. But
you can change the policy of a job any time. The UI can probably do
it, the CLI can definitely do it (isi job....)
Also, remember that if your goal is to increase free space on the
cluster, you should check that you don't have any snapshots in those
paths as those will cause OneFS to retain the blocks until the
snapshots expire. One of the fastest ways to bloat your snapshots
is to delete a bunch of data.
