操作环境

Centos 6.5

ceph 0.87

tgt

操作步骤

安装tgt

#wget http://ceph.com/packages/ceph-extras/rpm/centos6/x86_64/scsi-target-utils-1.0.38-48.bf6981.ceph.el6.x86_64.rpm#rpm -ivh scsi-target-utils-1.0.38-48.bf6981.ceph.el6.x86_64.rpm

查看当前tgt对于rbd driver是否支持

[root@ceph-osd-3 ~]# tgtadm --lld iscsi --mode system --op showSystem:    State: ready    debug: offLLDs:    iser: error    iscsi: readyBacking stores:    rbd (bsoflags sync:direct)    rdwr (bsoflags sync:direct)    ssc    null    bsg    sg    sheepdogDevice types:    passthrough    tape    changer    controller    osd    cd/dvd    diskiSNS:    iSNS=Off    iSNSServerIP=    iSNSServerPort=3205    iSNSAccessControl=Off

在Backing stores栏中可以看见rbd，说明该tgt可对rbd支持

创建tgt所需的pool以及rbd

[root@ceph-osd-1 ~]ceph osd pool create iscsi 256[root@ceph-osd-1 ~]rbd create tgt --size 10240 --pool iscsi

查看rbd

[root@ceph-osd-1 ~]# rbd ls --pool iscsitgt

添加以下内容至gt配置文件中

include /etc/tgt/conf.d/*.conf<target iqn.2014-11.rbdstore.com:iscsi>    driver iscsi    bs-type rbd    backing-store iscsi/tgt  </target>

重启tgtd

[root@ceph-osd-3 ~]# /etc/init.d/tgtd restartStopping target framework daemonStarting target framework daemon

在iscsi initiator端连接该iscsi target

[root@ceph-osd-1 ~]# iscsiadm -m discovery -t sendtargets -p 10.10.200.165Starting iscsid:                                           [  OK  ]10.10.200.165:3260,1 iqn.2014-11.rbdstore.com:iscsi[root@ceph-osd-1 ~]# iscsiadm -m node -T iqn.2014-11.rbdstore.com:iscsi -lLogging in to [iface: default, target: iqn.2014-11.rbdstore.com:iscsi, portal: 10.10.200.165,3260] (multiple)Login to [iface: default, target: iqn.2014-11.rbdstore.com:iscsi, portal: 10.10.200.165,3260] successful.[root@ceph-osd-1 ~]# fdisk -lDisk /dev/sdb: 5788.2 GB, 5788206759936 bytes255 heads, 63 sectors/track, 703709 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00000000Disk /dev/sda: 209.7 GB, 209715068928 bytes255 heads, 63 sectors/track, 25496 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x0009a9dd   Device Boot      Start         End      Blocks   Id  System/dev/sda1   *           1         131     1048576   83  LinuxPartition 1 does not end on cylinder boundary./dev/sda2             131        1176     8392704   82  Linux swap / Solaris/dev/sda3            1176       25497   195356672   8e  Linux LVMDisk /dev/mapper/vg_swift-LogVol00: 200.0 GB, 200043134976 bytes255 heads, 63 sectors/track, 24320 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00000000Disk /dev/mapper/docker-253:0-3539142-pool: 107.4 GB, 107374182400 bytes255 heads, 63 sectors/track, 13054 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 65536 bytesDisk identifier: 0x00000000Disk /dev/sdc: 10.7 GB, 10737418240 bytes64 heads, 32 sectors/track, 10240 cylindersUnits = cylinders of 2048 * 512 = 1048576 bytesSector size (logical/physical): 512 bytes / 4194304 bytesI/O size (minimum/optimal): 4194304 bytes / 4194304 bytesDisk identifier: 0x00000000

可以发现sdc为映射过来的新硬盘
