Permissions seems OK : # su ceph -s /bin/bash -c 'test -r /etc/pve/ceph.conf' && echo "Read OK" || echo "Read NOK" Read OK # su ceph -s /bin/bash -c 'test -w /etc/pve/ceph.conf' && echo "Write OK" || echo "Write NOK" Write NOK And if I run ceph-mds with "strace -e open", I can see it doesn't try to open any file before failing with "global_init: error reading config file."... _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
