5.2、存儲規劃
5.2.1劃分存儲（虛擬機一共分配了60G）
A機器：小于2TB的存儲使用fdisk命令來劃分 [root@~]# fdisk /dev/sdb1) 依次輸入 n p 1 回車 +100M，完成第一塊磁盤劃分2) 依次輸入 n p 2 回車 +100M，完成第二塊磁盤劃分3) 依次輸入 n p 3 回車 +20480M，完成第三塊磁盤劃分4) 依次輸入 n p 回車 回車 回車，完成第四塊磁盤劃分5) 輸入w命令，將裸設備劃分的設置進行保存A機器：大于2TB的需要使用parted命令來劃分 [root@~]# parted /dev/sdb1) 輸入 mklabel gpt 回車，將MBR磁盤磁盤轉換為gpt格式2) 輸入 mkpart primary 0 100 回車，完成第一塊磁盤劃分3) 輸入 mkpart primary 100 200 回車，完成第二塊磁盤劃分4) 輸入 mkpart primary 200 20680 回車，完成第三塊磁盤劃分5) 輸入 mkpart primary 20680 5498G 回車，完成第四塊磁盤劃分6) 輸入 quit 回車，完成磁盤劃分 ?A機器、B機器依次執行 [root@~]# partprobe /dev/sdb5.2.2掛存儲方法1：直接掛
A機器、B機器依次修改 [root@~]# vi /etc/udev/rules.d/70-persistent-ipoib.rulesACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"ACTION=="add", KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N"ACTION=="add", KERNEL=="sdb3", RUN+="/bin/raw /dev/raw/raw3 %N"ACTION=="add", KERNEL=="sdb4", RUN+="/bin/raw /dev/raw/raw4 %N"ACTION=="add", KERNEL=="raw[1-4]", OWNER="dmdba", GROUP="dinstall", MODE="660" [root@~]# partprobe /dev/sdb [root@~]# reboot 注意：可通過blockdev --getsize64 /dev/raw/raw*命令查看設備大小。5.2.3掛存儲方法2：多路徑綁定
使用命令ll /dev/mappr和ll /dev/dm*查看對應設備的信息 例如，/dev/mapper/mpathg1對應dm-3，主設備編號為253，次設備編號為3A機器、B機器依次修改 [root@~]# vi /etc/udev/rules.d/70-persistent-ipoib.rulesACTION=="add",ENV{MAJOR}=="253",ENV{MINOR}=="3",RUN+="/bin/raw /dev/raw/raw1 %M %m"ACTION=="add",ENV{MAJOR}=="253",ENV{MINOR}=="4",RUN+="/bin/raw /dev/raw/raw2 %M %m"ACTION=="add",ENV{MAJOR}=="253",ENV{MINOR}=="5",RUN+="/bin/raw /dev/raw/raw3 %M %m"ACTION=="add",ENV{MAJOR}=="253",ENV{MINOR}=="6",RUN+="/bin/raw /dev/raw/raw4 %M %m"ACTION=="add",KERNEL=="raw[1-4]",OWNER="dmdba",GROUP="dinstall",MODE="660" [root@~]# partprobe /dev/mapper/mpathg [root@~]# reboot 注意：可通過blockdev --getsize64 /dev/raw/raw*命令查看設備大小。5.3、搭建DSC
