So I haven't looked at this code in a while, but I think the monitor is trying to validate that it's consistent with the others. You probably want to dig around the monitor admin sockets and see what state each monitor is in, plus its perception of the others. In this case, I think maybe mon.computer06 is trying to examine its whole store, but 100GB is a lot (way too much, in fact), so this can take a loooong time. > > Sorry, my English is not good. > > _______________________________________________ > 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
