Great, thanks Josh! Using stdin/stdout merge-diff is working. Thank you for looking into this. -- Alex Gorbachev Storcium On Wed, Dec 9, 2015 at 2:25 PM, Josh Durgin wrote: > This is the problem: > > http://tracker.ceph.com/issues/14030 > > As a workaround, you can pass the first diff in via

This is the problem: http://tracker.ceph.com/issues/14030 As a workaround, you can pass the first diff in via stdin, e.g.: cat snap1.diff | rbd merge-diff - snap2.diff combined.diff Josh On 12/08/2015 11:11 PM, Josh Durgin wrote: On 12/08/2015 10:44 PM, Alex Gorbachev wrote: Hi Josh, On Mo
