RBD performance with many childs and snapshots

Hi, While implementing the buildvolfrom method in libvirt for RBD I'm stuck at some point. $ virsh vol-clone --pool myrbdpool image1 image2 This would clone image1 to a new RBD image called 'image2'. The code I've written now does: 1. Create a snapshot called image1@libvirt- 2. Protect the

RFC: tool for applying 'ceph daemon ' command to all OSDs

I needed something to fetch current config values from all OSDs (sorta the opposite of 'injectargs --key value), so I hacked it, and then spiffed it up a bit. Does this seem like something that would be useful in this form in the upstream Ceph, or does anyone have any thoughts on its design or

Time to move the make check bot to jenkins.ceph.com

Hi, The make check bot is broken in a way that I can't figure out right now. Maybe now is the time to move it to jenkins.ceph.com ? It should not be more difficult than launching the run-make-check.sh script. It does not need network or root access. Cheers -- Loïc Dachary, Artisan Logiciel

You will have to ensure that your writes are properly aligned with the object size (or object set if fancy striping is used on the RBD volume). In that case, the discard is translated to remove operations on each individual backing object. The only time zeros are written to disk is if you
