Hello, I just upgraded my cluster to the version 10.1.2 and it worked well for a while until I saw that systemctl ceph-disk@dev-sdc1.service was failed and I reruned it. >From there the OSD stopped working. This is ubuntu 16.04. I connected to the IRC looking for help where people pointed me to one or another place but none of the investigations helped to resolve. My configuration is rather simple: oot@red-compute:~# ceph osd tree ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY -1 1.00000 root default -4 1.00000 rack rack-1 -2 1.00000 host blue-compute 0 1.00000 osd.0 down 0 1.00000 2 1.00000 osd.2 down 0 1.00000 -3 1.00000 host red-compute 1 1.00000 osd.1 down 0 1.00000 3 0.50000 osd.3 up 1.00000 1.00000 4 1.00000 osd.4 down 0 1.00000 It seems that all nodes are in preboot status. I was looking at the latests commits and it seems that there's a patch to make OSDs to wait for cluster to become healthy before rejoining. Can this be the source of my problems? root@red-compute:/var/lib/ceph/osd/ceph-1# ceph daemon osd.1 status { "cluster_fsid": "9028f4da-0d77-462b-be9b-dbdf7fa57771", "osd_fsid": "adf9890a-e680-48e4-82c6-e96f4ed56889", "whoami": 1, "state": "preboot", "oldest_map": 1764, "newest_map": 2504, "num_pgs": 323 } root@red-compute:/var/lib/ceph/osd/ceph-1# ceph daemon osd.3 status { "cluster_fsid": "9028f4da-0d77-462b-be9b-dbdf7fa57771", "osd_fsid": "8dd085d4-0b50-4c80-a0ca-c5bc4ad972f7", "whoami": 3, "state": "preboot", "oldest_map": 1764, "newest_map": 2504, "num_pgs": 150 } 3 is up and in. This is what I got sofar: Once upgraded I discovered that daemon runs under ceph. I just ran chown on ceph directories. and it worked. Firewall is fully disabled. Checked connectivity with nc and nmap. Configuration seems to be right. I can post if you want. Enabling logging on OSD shows that for example osd.1 is reconnecting all the time. 2016-05-10 14:35:48.199573 7f53e8f1a700 1 -- 0.0.0.0:6806/13962 >> :/0 pipe(0x556f99413400 sd=84 :6806 s=0 pgs=0 cs=0 l=0 c=0x556f993b3a80).accept sd=84 172.16.0.119:35388/0 2016-05-10 14:35:48.199966 7f53e8f1a700 2 -- 0.0.0.0:6806/13962 >> :/0 pipe(0x556f99413400 sd=84 :6806 s=4 pgs=0 cs=0 l=0 c=0x556f993b3a80).fault (0) Success 2016-05-10 14:35:48.200018 7f53fb941700 1 osd.1 2468 ms_handle_reset con 0x556f993b3a80 session 0 OSD.3 goes ok because never left out because ceph restriction. I rebooted all services at once for it to have available all OSD at the same time and don't mark it down. Don't work. I forced up from commandline. ceph osd in 1-5. They appear as in for a while then out. We tried ceph-disk activate-all to boot everything. Don't work. The strange thing is that culster started worked just right after upgrade. But the systemctrl command broke both servers. root@blue-compute:~# ceph -w cluster 9028f4da-0d77-462b-be9b-dbdf7fa57771 health HEALTH_ERR 694 pgs are stuck inactive for more than 300 seconds 694 pgs stale 694 pgs stuck stale too many PGs per OSD (1528 > max 300) mds cluster is degraded crush map has straw_calc_version=0 monmap e10: 2 mons at {blue-compute=172.16.0.119:6789/0,red- compute=172.16.0.100:6789/0} election epoch 3600, quorum 0,1 red-compute,blue-compute fsmap e673: 1/1/1 up {0:0=blue-compute=up:replay} osdmap e2495: 5 osds: 1 up, 1 in; 5 remapped pgs pgmap v40765481: 764 pgs, 6 pools, 410 GB data, 103 kobjects 87641 MB used, 212 GB / 297 GB avail 694 stale+active+clean 70 active+clean 2016-05-10 17:03:55.822440 mon.0 [INF] HEALTH_ERR; 694 pgs are stuck inactive for more than 300 seconds; 694 pgs stale; 694 pgs stuck stale; too many PGs per OSD (1528 > max 300); mds cluster is degraded; crush map has straw_calc_version= cat /etc/ceph/ceph.conf [global] fsid = 9028f4da-0d77-462b-be9b-dbdf7fa57771 mon_initial_members = blue-compute, red-compute mon_host = 172.16.0.119, 172.16.0.100 auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx filestore_xattr_use_omap = true public_network = 172.16.0.0/24 osd_pool_default_pg_num = 100 osd_pool_default_pgp_num = 100 osd_pool_default_size = 2 # Write an object 3 times. osd_pool_default_min_size = 1 # Allow writing one copy in a degraded state. ## Required upgrade osd max object name len = 256 osd max object namespace len = 64 [mon.] debug mon = 9 caps mon = "allow *" Any help on this?
