Strage RBD images created
Greetings, I am running a mimic cluster. I noticed that I suddenly have over 200 rbd images that have seemingly random 64 character names. They were all created within a short time period. rbd info on one of the rbds looks like this: rbd image 'ff8f0ad0b5323fc3a8e930d96d3021d4c4dfc18c62ef9a1305b49456b8560904': size 16 GiB in 4096 objects order 22 (4 MiB objects) id: cb09e16b8b4567 block_name_prefix: rbd_data.cb09e16b8b4567 format: 2 features: layering op_features: flags: create_timestamp: Fri Mar 1 11:19:14 2019 `rbd lock ls` shows that these images are not being used. I can certainly delete them but I found it odd that they showed up at all. Has anyone seen anything like this? -- Randall Smith Computing Services Adams State University http://www.adams.edu/ 719-587-7741

Never seen anything like that. I wouldn't know anything that would create RBD images. Something outside Ceph must have asked for this. What kind of application are you running on top of Ceph? Wido

I'm running KVM and Docker with the rexray storage driver. I kinda figured that something else triggered the creation, it's just weird.
