[ceph-users] rbd resize progress report?

I'm trying to resize a block device using "rbd --resize". The block device is pretty huge (100+ TB). The resize has been running for over a week, and I have no idea if it's actually doing anything, or if it's just hanging or in some infinite loop. Is there any way of getting a progress report from the resize to get an idea if this is ever going to finish? Thanks!
