Thanks Greg. I think I have to re-install ceph v13 from scratch then.

I’m wondering if rollback/downgrade is supported at all ? After compiling/starting ceph-13 I’m running into a permission error.

Any help is greatly appreciated. Unfortunately this is generally not possible. Disk encodings change across major versions and the old code can't understand what's been written down once the new code runs. -Greg Thanks, Raj _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com<mailto:ceph-users@lists.ceph.com> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
