The ceph-objectstore-tool also has an (experimental?) mode to mount the OSD store as a FUSE Filesystems regardless of the backend. But I have to assume what you’re really after here is repairing individual objects, and the way that works is enough different in BlueStore I really wouldn’t worry about it. The advantage of looking at the raw FileStore filesystem was you could fix issues the FS had caused, but obviously BlueStore doesn’t experience those. -Greg On Thu, Jun 28, 2018 at 1:54 PM Igor Fedotov <ifedo...@suse.de> wrote:
