Dear Kurt,

Apologies.  After leaving it some number of days it did *not* clean itself up, but I feel that some number of days is long enough to verify that it is a problem.

Sounds like you have another issue if the OST is not being marked as full and writes are not being re-allocated to other OSTS .  I also have that second issue on my system as well and I have only workarounds to offer you for the problem.

The problem there is that I cannot afford to leave it "some number of days"... it is at 97% full, so new writes are going to it faster then it can clean itself off.

The 'space not freed' issue also happened to me and I left it 'some number of days'  I don't recall how many, it was a while back.
