Re: [ceph-users] what means active+clean+scrubbing+deep
Hi Ryan, it means that the PG is in good health (clean), is available (active) and that deep scrubbing is currently being performed (scrubbing+deep) JC On 13 Mar 2015, at 17:59, ryan_h...@supercluster.cn wrote: Hi all, Anyone knows what means 'active+clean+scrubbing+deep' ? ryan_h...@supercluster.cn ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

Re: [ceph-users] what means active+clean+scrubbing+deep
Hi Ryan, it means that the OSDs are physically reading the whole content of the PG, recalculating the checksum of each object to verify that the content of the PG is identical on each OSD protecting the PG. This is to make sure the data that was written to the underlying filesystem of each OSD is identical and hasn't been altered. So to make it short the OSDs are checking the coherence of the data stored in the PG.
