Hi Victor,
As Andrey said, running cleanup doesn't work as you expect.

inserted data on the next day.
Deleted objects(columns/records) become deletable from sstable file when
they get expired(after gc_grace_seconds).
Such deletable objects are actually gotten rid of by compaction.
The tricky part is that a deletable object remains unless all of its old
objects(the same row key) are contained in the set of sstable files
involved in the compaction.

cleanup removes data which doesn't belong to the current node. You
have to run it only if you move (or add new) nodes. In your case there
is no any reason to do it.

Hello everyone.
I have a daily maintenance task at c* which does:
-truncate cfs
-clearsnapshots
-repair
-cleanup
The reason I need to clean things is that I wont need most of my
inserted data on the next day. It's kind a business requirement.
Well, the problem I'm running to, is the misunderstanding about
cleanup operation.
I have 2 nodes with lower than half usage of disk, which is
moreless 13GB;
But, the last few days, arbitrarily each node have reported me a
cleanup error indicating that the disk was full. Which is not true.
/Error occured during cleanup/
/java.util.concurrent.ExecutionException: java.io.IOException:
disk full/
So I'd like to know more about what does happens in a cleanup
operation.
Appreciate any help.
