Hi cephers, Have anyone ever created osd with btrfs in Hammer 0.94.3 ? I can create btrfs partition successfully. But once use "ceph-deploy" then always get error like below. Another question there is no parameter " -f " with mkfs. Any suggestion is appreciated. --------------------------------------------------------------------- [osd3][DEBUG ] The operation has completed successfully.
