Hello all, I fresh deployed Ceph within 3 ceph nodes according to the manual http://docs.ceph.com/docs/master/start/quick-ceph-deploy/. Ceph version is Jewel (ceph version 10.2.1 (3a66dd4f30852819c1bdaa8ec23c795d4ad77269)). Ubuntu 16.04 is used in each node. After run the command "ceph-deploy osd activate", there is warning reported, following an ERROR, ENAMETOOLONG. After check in each ceph OSD node, the ceph osd daemon is not start up. According to the installation manual, the below options are not mandatory: filestore_max_xattr_value_size_XXX osd_max_object_name_len In the source code, the value of filestore_max_xattr_value_size_XXX should be over the value of osd_max_object_name_len, otherwise the error, ENAMETOOLONG, will be reported. logical if the options are not mandatory, I think the OSD daemon should NOT be blocked. So it should be one bug. Right? I can reproduce the problem in Jewel and in the source code building from the latest master branch (version is 9661bbbbd7d0f03095039184f8ed9fb92855d576). Now the question is that is it one bug? Is there any history behind? If it is a bug, I'd like to fix it. What's you opinion? Any suggestion? I have created one bug to track the issue http://tracker.ceph.com/issues/16070. Thanks.
