Hello, I suspect there was unwritten data in RAM which didn't make it to the disk. This shoudn't happen, that's why the journal is in place. If you have size=2 in you pool, there is one copy on the other host. Do delete the OSD you could probably do ceph osd crush remove osd.x ceph osd rm osd.x ceph auth del osd.x maybe "wipefs -a /dev/sdxxx" or dd if=/dev/zero of=dev/sdxx count=1 bs=1m ... Then you should be able deploy the disk again with the tool that you used originally. The disk should be "fresh". rgds, derjohn.
