Username and password updated 二、ceph集群添加或移除主机 1.查看现有的集群主机列表 [rootceph141 ~]# ceph orch host ls HOST ADDR LABELS STATUS
ceph141 10.0.0.141 _admin
1 hosts in cluster 2.拷贝密钥到其他服务器上 [rootceph141 ~]# ssh-copy-id -f -i /etc/ceph/ceph.pub ceph142 [rootceph141 ~]# ssh-copy-id -f -i /etc/ceph/ceph.pub ceph143 3.将密钥节点加入集群 [rootceph141 ~]# ceph orch host add ceph142 10.0.0.142 Added host ceph142 with addr 10.0.0.142[rootceph141 ~]# ceph orch host add ceph143 10.0.0.143 Added host ceph143 with addr 10.0.0.143 4.再次查看主机列表 [rootceph141 ~]# ceph orch host ls HOST ADDR LABELS STATUS
ceph141 10.0.0.141 _admin
ceph142 10.0.0.142
ceph143 10.0.0.143
3 hosts in cluster 当然也可以通过查看WebUI观察ceph集群有多少个主机。 5.移除主机【选做如果你将来真有这个需求在操作】 [rootceph141 ~]# ceph orch host rm ceph143 Removed host ceph143 [rootceph141 ~]# [rootceph141 ~]# ceph orch host ls HOST ADDR LABELS STATUS
ceph141 10.0.0.141 _admin
ceph142 10.0.0.142
2 hosts in cluster 三、添加OSD设备到ceph集群 1.添加OSD之前环境查看 查看集群可用的设备【每个设备想要加入到集群则其大小不得小于5GB】 如果一个设备想要加入ceph集群要求满足2个条件: 1.设备未被使用; 2.设备的存储大小必须大于5GB; [rootceph141 ~]# ceph orch device ls HOST PATH TYPE DEVICE ID SIZE AVAILABLE REFRESHED REJECT REASONS
ceph141 /dev/sdc hdd 200G Yes 10m ago
ceph141 /dev/sr0 hdd VMware_Virtual_SATA_CDRW_Drive_01000000000000000001 2006M No 10m ago Has a FileSystem, Insufficient space (5GB)

查看各节点的空闲设备信息 [rootceph141 ~]# lsblk …. sdb 8:16 0 200G 0 disk sdc 8:32 0 100G 0 disk ….[rootceph142 ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS … sdb 8:16 0 200G 0 disk sdc 8:32 0 100G 0 disk …[rootceph143 ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS … sdb 8:16 0 200G 0 disk sdc 8:32 0 100G 0 disk 查看OSD列表 [rootceph141 ~]# ceph osd tree ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF -1 0 root default
添加OSD设备到集群 此步骤会在/var/lib/ceph/Ceph_Cluster_ID/osd.OSD_ID/fsid文件中记录对应ceph的OSD编号对应本地的磁盘设备标识。 [rootceph141 ~]# ceph orch daemon add osd ceph141:/dev/sdb Created osd(s) 0 on host ceph141 [rootceph141 ~]# ceph orch daemon add osd ceph141:/dev/sdc Created osd(s) 1 on host ceph141 [rootceph141 ~]# ceph orch daemon add osd ceph142:/dev/sdb Created osd(s) 2 on host ceph142 [rootceph141 ~]# ceph orch daemon add osd ceph142:/dev/sdc Created osd(s) 3 on host ceph142 [rootceph141 ~]# ceph orch daemon add osd ceph143:/dev/sdb Created osd(s) 4 on host ceph143 查看ceph节点的硬盘和OSD的对应关系 [rootceph141 ~]# ll -d /var/lib/ceph//osd. drwx—— 2 167 167 4096 Jan 23 11:19 /var/lib/ceph/c153209c-d8a0-11ef-a0ed-bdb84668ed01/osd.0/ drwx—— 2 167 167 4096 Jan 23 11:19 /var/lib/ceph/c153209c-d8a0-11ef-a0ed-bdb84668ed01/osd.1/[rootceph141 ~]# cat /var/lib/ceph//osd./fsid 1eb45f98-6058-42f2-a5bf-b034e008ac9b 96e33e3d-0acc-43f5-bcee-204feb1582c7[rootceph142 ~]# ll -d /var/lib/ceph//osd. drwx—— 2 167 167 4096 Jan 23 11:21 /var/lib/ceph/c153209c-d8a0-11ef-a0ed-bdb84668ed01/osd.2/ drwx—— 2 167 167 4096 Jan 23 11:21 /var/lib/ceph/c153209c-d8a0-11ef-a0ed-bdb84668ed01/osd.3/[rootceph142 ~]# cat /var/lib/ceph//osd./fsid 3957c37c-c2fe-4783-984e-93c1184b74a3 b8d5b119-c3e3-4e4e-aab5-85bea49ae3ef[rootceph143 ~]# ll -d /var/lib/ceph//osd. drwx—— 2 167 167 4096 Jan 23 11:22 /var/lib/ceph/c153209c-d8a0-11ef-a0ed-bdb84668ed01/osd.4/ drwx—— 2 167 167 4096 Jan 23 11:27 /var/lib/ceph/c153209c-d8a0-11ef-a0ed-bdb84668ed01/osd.5/[rootceph143 ~]# cat /var/lib/ceph//osd./fsid e73be677-e55e-4b54-b007-a0ed5ba07316 2732dd29-342e-4290-ba2b-1b56924339ec 不难发现ceph底层是基于lvm技术磁盘的。 查看集群的osd总容量大小   [rootceph141 ~]# ceph osd tree ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF -1 0.87895 root default
