1、查看OSD的分布信息:
# ceph osd tree ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY -1 0.21950 root default -2 0.04390 host hz-01-ops-tc-ceph-01 0 0.04390 osd.0 up 1.00000 1.00000 -3 0.04390 host hz-01-ops-tc-ceph-02 1 0.04390 osd.1 up 1.00000 1.00000 -4 0.04390 host hz-01-ops-tc-ceph-03 2 0.04390 osd.2 up 1.00000 1.00000 -5 0.04390 host hz-01-ops-tc-ceph-04 3 0.04390 osd.3 up 1.00000 1.00000 -6 0.04390 host hz01-dev-ops-wanl-01 4 0.04390 osd.4 up 1.00000 1.00000
2、将osd.4移除OSD
# ceph osd out 4 marked out osd.4. # ceph -s cluster e2ca994a-00c4-477f-9390-ea3f931c5062 health HEALTH_WARN 56 pgs degraded 1 pgs recovering 55 pgs recovery_wait 56 pgs stuck unclean recovery 604/1692 objects degraded (35.697%) monmap e1: 3 mons at {hz-01-ops-tc-ceph-02=172.16.2.231:6789/0,hz-01-ops-tc-ceph-03=172.16.2.172:6789/0,hz-01-ops-tc-ceph-04=172.16.2.181:6789/0} election epoch 20, quorum 0,1,2 hz-01-ops-tc-ceph-03,hz-01-ops-tc-ceph-04,hz-01-ops-tc-ceph-02 osdmap e89: 5 osds: 5 up, 4 in flags sortbitwise,require_jewel_osds pgmap v68654: 1172 pgs, 4 pools, 2159 MB data, 564 objects 5491 MB used, 174 GB / 179 GB avail 604/1692 objects degraded (35.697%) 1116 active+clean 55 active+recovery_wait+degraded 1 active+recovering+degraded recovery io 87376 kB/s, 1 keys/s, 23 objects/s
3、在被删除OSD的那台ceph节点上的操作:
# systemctl stop [email protected] # ceph osd tree ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY -1 0.21950 root default -2 0.04390 host hz-01-ops-tc-ceph-01 0 0.04390 osd.0 up 1.00000 1.00000 -3 0.04390 host hz-01-ops-tc-ceph-02 1 0.04390 osd.1 up 1.00000 1.00000 -4 0.04390 host hz-01-ops-tc-ceph-03 2 0.04390 osd.2 up 1.00000 1.00000 -5 0.04390 host hz-01-ops-tc-ceph-04 3 0.04390 osd.3 up 1.00000 1.00000 -6 0.04390 host hz01-dev-ops-wanl-01 4 0.04390 osd.4 down 0 1.00000 # ceph osd crush remove osd.4 removed item id 4 name 'osd.4' from crush map # ceph auth del osd.4 updated # ceph osd tree ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY -1 0.17560 root default -2 0.04390 host hz-01-ops-tc-ceph-01 0 0.04390 osd.0 up 1.00000 1.00000 -3 0.04390 host hz-01-ops-tc-ceph-02 1 0.04390 osd.1 up 1.00000 1.00000 -4 0.04390 host hz-01-ops-tc-ceph-03 2 0.04390 osd.2 up 1.00000 1.00000 -5 0.04390 host hz-01-ops-tc-ceph-04 3 0.04390 osd.3 up 1.00000 1.00000 -6 0 host hz01-dev-ops-wanl-01 4 0 osd.4 down 0 1.00000 # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/cl-root 39G 1.8G 37G 5% / devtmpfs 486M 0 486M 0% /dev tmpfs 497M 84K 497M 1% /dev/shm tmpfs 497M 26M 472M 6% /run tmpfs 497M 0 497M 0% /sys/fs/cgroup /dev/vda1 1014M 121M 894M 12% /boot /dev/mapper/cl-home 19G 33M 19G 1% /home /dev/vdb1 45G 237M 45G 1% /var/lib/ceph/osd/ceph-4 tmpfs 100M 0 100M 0% /run/user/0 # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 1024M 0 rom vda 252:0 0 60G 0 disk ├─vda1 252:1 0 1G 0 part /boot └─vda2 252:2 0 59G 0 part ├─cl-root 253:0 0 38.3G 0 lvm / ├─cl-swap 253:1 0 2G 0 lvm [SWAP] └─cl-home 253:2 0 18.7G 0 lvm /home vdb 252:16 0 50G 0 disk ├─vdb1 252:17 0 45G 0 part /var/lib/ceph/osd/ceph-4 └─vdb2 252:18 0 5G 0 part # ceph -s cluster e2ca994a-00c4-477f-9390-ea3f931c5062 health HEALTH_OK monmap e1: 3 mons at {hz-01-ops-tc-ceph-02=172.16.2.231:6789/0,hz-01-ops-tc-ceph-03=172.16.2.172:6789/0,hz-01-ops-tc-ceph-04=172.16.2.181:6789/0} election epoch 20, quorum 0,1,2 hz-01-ops-tc-ceph-03,hz-01-ops-tc-ceph-04,hz-01-ops-tc-ceph-02 osdmap e79: 4 osds: 4 up, 4 in flags sortbitwise,require_jewel_osds pgmap v68497: 1164 pgs, 3 pools, 2159 MB data, 564 objects 6655 MB used, 173 GB / 179 GB avail 1164 active+clean
