Created attachment 1166194 [details] All Features Description of problem: While reading Image Metadata of an Image from Master Node, i am seeing the Error message Version-Release number of selected component (if applicable): rbd-mirror-10.2.1-12.el7cp.x86_64 How reproducible: Once Steps to Reproduce: 1. Create an Image without enabling Journal 2. Write some Data on to it. 3. Set Image Metadata on that Image. for i in `cat features`; do rbd image-meta set RBD/tanay $i 1024 --cluster master; done (PFA) 4. Enable Journaling 5. Read the Image Metadata from the Slave Node. for i in `cat features`; do rbd image-meta get RBD/tanay $i --cluster slave; done Actual results: It should show all the Image Metadata values which are already set for that Image from the Slave Node as well 2016-06-09 07:53:02.309938 7fad38cb6d80 20 librbd: metadata_get 0x7fad437f49a0 key=rbd_journal_pool failed to get metadata rbd_journal_pool of image : (2) No such file or directory rbd: getting metadata failed: (2) No such file or directory Expected results: Its not showing Additional info: ------------------------------------------------------------------------------ rbd -p RBD ls --cluster slave 2016-06-09 07:55:11.473290 7f5ce3a57d80 20 librbd: list 0x7ffd6c57a040 2016-06-09 07:55:11.474596 7f5ce3a57d80 20 librbd: list_images_v2 0x7ffd6c57a040 tanay # systemctl status -l ceph-rbd-mirror@slave ● ceph-rbd-mirror@slave.service - Ceph rbd mirror daemon Loaded: loaded (/usr/lib/systemd/system/ceph-rbd-mirror@.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2016-06-09 07:45:24 UTC; 9min ago Main PID: 14373 (rbd-mirror) CGroup: /system.slice/system-ceph\x2drbd\x2dmirror.slice/ceph-rbd-mirror@slave.service └─14373 /usr/bin/rbd-mirror -f --cluster slave --id slave --setuser ceph --setgroup ceph Jun 09 07:45:24 magna003 systemd[1]: Started Ceph rbd mirror daemon.
