hi,
I have a ceph cluster that use keyvaluestore-dev. After upgraded from v0.87 to v0.94.1, and changed the configuration (removed "-dev" suffix and added "enable experimental ..."), OSD is still fail to start, with the following error:
7fb8b06ce900 -1 osd.0 0 OSD::init() : unable to read osd superblock
7fb8b06ce900 -1 ** ERROR: osd init failed: (22) Invalid argument
any idea if such upgrade is supported? how can I troubleshoot the problem? thx
regards,
mingfai
