Hi, I'm not sure, but it might be the same issue as discussed here: https://bugzilla.novell.com/show_bug.cgi?id=539521 Comment #16 mentions two commits from parted-git; after posting this comment, I found out that these two are not always enough to fix the issue, so please add the quick and dirty patch attached to this mail. With these three patches, I was not able to reproduce -EBUSY anymore.
