Hi, On a Ceph cluster running Jewel 10.2.5 I'm running into a problem. I want to change the amount of shards: # radosgw-admin zonegroup-map get > zonegroup.json # nano zonegroup.json # radosgw-admin zonegroup-map set --infile zonegroup.json # radosgw-admin period update --commit Now, the error arrises: cannot commit period: period does not have a master zone of a master zonegroup failed to commit period: (22) Invalid argument Looking at the output: # radosgw-admin period update { ... "master_zonegroup": "", "master_zone": "", ... } # radosgw-admin zone list { "default_info": "zm1", "zones": [ "default", "zm1" ] } To me it seems like there is something wrong with the period since there is no UUID present in master_zone/zonegroup. Any idea on how to fix this? Wido _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
