[ceph-users] osdmap several thousand epochs behind latest
All, Had a fairly substantial network interruption that knocked out about ~270 osds: health HEALTH_ERR [...] 273/384 in osds are down noup,nodown,noout flag(s) set monmap e2: 3 mons at {cephmon-0=10.10.6.0:6789/0,cephmon-1=10.10.6.1:6789/0,cephmon-2=10.10.6.2:6789/0} election epoch 138, quorum 0,1,2 cephmon-0,cephmon-1,cephmon-2 mgr no daemons active osdmap e37718: 384 osds: 111 up, 384 in; 16764 remapped pgs flags noup,nodown,noout,sortbitwise,require_jewel_osds,require_kraken_osds We've had network interruptions before, and normally OSDs come back on their own, or do so with a service restart. This time, no such luck (I'm guessing the scale was just too much). After a few hours of trying to figure out why OSD services were running on the hosts (according to systemd) but marked 'down' in ceph osd tree, I found this thread: http://ceph-devel.vger.kernel.narkive.com/ftEN7TOU/70-osd-are-down-and-not-coming-up which appears to perfectly describe the scenario (high CPU usage, osdmap way out of sync, etc.) I've taken the steps outlined and set the appropriate flags and am monitoring the 'catch up' progress of the OSDs. The OSD farthest behind is about 5000 epochs out of sync, so I assume it will be a few hours before I see CPU usage level out. Once the OSDs are caught up, are there any other steps I should take before 'ceph osd unset noup' (or anything to do after)?

These are the > stock packages: I suspect that you may need the package 'qemu-block-extra' installed. It has a dependency on such things as librados2, librbd1 (for Ceph) and glusterfs-common, libiscsi7, etc. From the package description: "This package provides extra block device backend modules for qemu-system emulation and qemu-img from qemu-utils package, which are rarely used and has extra dependencies." -- David Clarke Systems Architect Catalyst IT signature.asc Description: OpenPGP digital signature ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
