Not "cleanup", it is "--no-cleanup"
I wanted to delete the benchdata, not to keep it:)

Subject: [ceph-users] rados bench no clean cleanup
Hi,
I did a test with 'rados -p ecdata bench 100000 write' on an ECpool
with a cache replicated pool over it (ceph 0.83).
The benchmark wrote about 12TB of data. After the 100000 seconds
run, rados started to delete his benchmark files.
But only about 2,5TB got deleted, then rados returned. I tried to do
it with the cleanup function 'rados -p ecdata cleanup --prefix bench'
and after a lot of time, it returns:
Warning: using slow linear search
Removed 2322000 objects
But rados df showed the same statistics as before.
I ran it again, and it again showed 'Removed 2322000 objects',
without any change in the rados df statistics.
It is probably the 'lazy deletion', because if I try to do a 'rados
get' on it, there is 'No such file or directory'. But I still see
the objects when I do 'rados -p ecdata ls'.
Is this indeed because of the lazy deletion? Is there a way to see
how much not-deleted objects are in the pool? And is there then a
reason why rados did remove the first 2,5TB? Or is this just a rados
bench issue?:)
Thanks again!
Kenneth
