RHCE7.0答案之ISCSI客户端

Posted 2020-08-16

ISCSI客户端配置：

1. yum install iscsi-initiator-utils

2. vim /etc/iscsi/initiatorname.iscsi

   InitiatorName = iqn.2014-11...:Desktop0

3. systemctl restart iscsid.service

   systemctl enable iscsid(与服务器通讯)

   systemctl restart iscsi(读取iscsi文件)

   systemctl enable iscsi

4. iscsiadm -m discovery -t st(send target) -p server0 可以man iscsiadmin 查看

5. yum -y install tree

   tree /var/lib/iscsi/

6. systemctl restart iscsi

7. fdisk -l 可看到/dev/sda的盘，只要保证iscsi开启并且/var/lib/iscsi里的内容还在，那么开机后就会有iscsi的盘

8. fdisk /dev/sda; n,p,+500M,w,partprobe

   mkfs.xfs /dev/sda1

   mkdir /iscsidisk; blkid  获取UUID，用来挂载

9. vim /etc/fstab

   UUID = "..." /iscsidisk xfs defaults, _netdev 0 0

10. mount -a 重启后查看是否挂载

11. 出错时可以用： rm -rf /var/lib/iscsi/*  再重新做一遍
