Hi, Ceph hammer has been released and have a cool new feature called object map https://wiki.ceph.com/Planning/Blueprints/Hammer/librbd%3A_shared_flag%2C_object_map
which allow fast resize, snapshots,.... (and also async). This require ceph hammer and librbd hammer, and require rbd volume settings: -exclusive locking + objectmap enable. (can be done with rbd cli). I would like to implement this, but I don't know which is the best place for this option: -storage.cfg (rbd plugin) ? this will enable exclusive locking globally, but maybe users want to share some rbd volume across multiple vms (with ocfs2 on top of rbd virtio device for example) -in qemu drive options This could allow to enable|disable locking by disk easily. But this is very rbd specific. Any opinions? _______________________________________________ pve-devel mailing list [email protected] http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
