Centos7下安装配置开源存储虚拟化QuadStor（4）----Vdisk Clone

操作环境

同《 Centos7下安装配置开源存储虚拟化QuadStor（1）------初始化QuadStor》

QuadStor Server：10.10.200.227

iSCSi Initiator：10.10.200.50

操作步骤

1.创建Vdisk，名称设置为sourcedisk，容量为500GB

2.在iscsi initiator端挂在vdisk

[root@centos7-nfstest /]# iscsiadm -m discovery -t st -p 10.10.200.227
10.10.200.227:3260,1 iqn.2006-06.com.quadstor.vdisk.sourcedisk
[root@centos7-nfstest /]# iscsiadm -m node -T iqn.2006-06.com.quadstor.vdisk.sourcedisk -l
Logging in to [iface: default, target: iqn.2006-06.com.quadstor.vdisk.sourcedisk, portal: 10.10.200.227,3260] (multiple)
Login to [iface: default, target: iqn.2006-06.com.quadstor.vdisk.sourcedisk, portal: 10.10.200.227,3260] successful.

3.在iscsi initiator端向sdc（vdisk）中写入数据

[root@centos7-nfstest source]# df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/centos-root   14G   11G  2.7G  81% /
devtmpfs                 3.9G     0  3.9G   0% /dev
tmpfs                    3.9G     0  3.9G   0% /dev/shm
tmpfs                    3.9G  8.5M  3.9G   1% /run
tmpfs                    3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/sda1               1014M  189M  826M  19% /boot
/dev/sdb                 100G  5.1G   95G   6% /mnt
tmpfs                    799M     0  799M   0% /run/user/0
/dev/sdc                 500G  7.6G  493G   2% /source

4.在quadstor server中对vdisk：sourcedisk进行clone，quadstor只能手动clone，不能自动clone

[root@quadstor-node1 bin]# ./qclone -s sourcedisk -d clonedisk2
Clone of sourcedisk to clonedisk2 successfully started

5.查看clone进度

[root@quadstor-node1 bin]# ./qclone -l
Source     Destination Progress Time 
sourcedisk clonedisk2  0%       3.3  
[root@quadstor-node1 bin]# ./qclone -l
Source     Destination Progress Time 
sourcedisk clonedisk2  0%       5.4  
[root@quadstor-node1 bin]# ./qclone -l
Source     Destination Progress Time 
sourcedisk clonedisk2  25%      6.1  
[root@quadstor-node1 bin]# ./qclone -l
Source     Destination Progress Time 
sourcedisk clonedisk2  25%      6.9  

如果clone进度完成后，显示如下

[root@quadstor-node1 bin]# ./qclone -l
Source     Destination Progress Time 
sourcedisk clonedisk2  Done     19.5 

6.通过iscsi initiator连接clone vdisk：clonedisk2查看数据是否一致

[root@quadstor-node1 bin]# ./qclone -s sourcedisk -d clonedisk2
Clone of sourcedisk to clonedisk2 successfully started
[root@centos7-nfstest /]# iscsiadm -m discovery -t st -p 10.10.200.227
10.10.200.227:3260,1 iqn.2006-06.com.quadstor.vdisk.sourcedisk
10.10.200.227:3260,1 iqn.2006-06.com.quadstor.vdisk.clonedisk2
[root@centos7-nfstest /]# iscsiadm -m node -T iqn.2006-06.com.quadstor.vdisk.clonedisk2 -l
Logging in to [iface: default, target: iqn.2006-06.com.quadstor.vdisk.clonedisk2, portal: 10.10.200.227,3260] (multiple)
Login to [iface: default, target: iqn.2006-06.com.quadstor.vdisk.clonedisk2, portal: 10.10.200.227,3260] successful.

查看硬盘，sdd为sdc的clone disk

[root@centos7-nfstest /]# lsscsi 
[0:0:0:0]    disk    VMware   Virtual disk     1.0   /dev/sda 
[0:0:1:0]    disk    VMware   Virtual disk     1.0   /dev/sdb 
[2:0:0:0]    cd/dvd  NECVMWar VMware IDE CDR10 1.00  /dev/sr0 
[10:0:0:0]   disk    QUADSTOR VDISK            2.0   /dev/sdc 
[11:0:0:0]   disk    QUADSTOR VDISK            2.0   /dev/sdd 

挂在sdd

[root@centos7-nfstest /]# mount /dev/sdd /clone
mount: wrong fs type, bad option, bad superblock on /dev/sdd,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

提示报错，查看日志，提示uuid重复

[root@centos7-nfstest /]# tail -f /var/log/messages

添加nouuid参数进行挂载

[root@centos7-nfstest /]# mount -o nouuid /dev/sdd /clone/
