Hi, On a Ceph Luminous (12.2.1) environment I'm seeing RGWs stall and about the same time I see these errors in the RGW logs: 2017-11-06 15:50:24.859919 7f8f5fa1a700 0 ERROR: failed to distribute cache for gn1-pf.rgw.data.root:.bucket.meta.XXXXX:eb32b1ca-807a-4867-aea5-ff43ef7647c6.20755572.20 2017-11-06 15:50:41.768881 7f8f7824b700 0 ERROR: failed to distribute cache for gn1-pf.rgw.data.root:XXXXX 2017-11-06 15:55:15.781739 7f8f7824b700 0 ERROR: failed to distribute cache for gn1-pf.rgw.meta:.meta:bucket.instance:XXXXX:eb32b1ca-807a-4867-aea5-ff43ef7647c6.20755572.32:_XK5LExyXXXXX6EEIXxCD5Cws:1 2017-11-06 15:55:25.784404 7f8f7824b700 0 ERROR: failed to distribute cache for gn1-pf.rgw.data.root:.bucket.meta.XXXXX:eb32b1ca-807a-4867-aea5-ff43ef7647c6.20755572.32 I see one message from a year ago: http://lists.ceph.com/pipermail/ceph-users-ceph.com/2016-June/010531.html The setup has two RGWs running: - ceph-rgw1 - ceph-rgw2 While trying to figure this out I see that a "radosgw-admin period pull" hangs for ever. I don't know if that is related, but it's something I've noticed. Mainly I see that at random times the RGW stalls for about 30 seconds and while that happens these messages show up in the RGW's log. Is anybody else running into this issue? Wido _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
