为zLinux快速扩展磁盘空间的步骤

Writing inode tables: done

Creating journal (16384 blocks): done

Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 24 mounts or

180 days, whichever comes first.  Use tune2fs -c or -i to override.

Step 6 设置自动加载

将 rd_DASD=0.0.0101加入开机配置文件/etc/zipl.conf，以使虚拟机在开机时能自动加载这块盘。

修改后的/etc/zipl.conf为

[linux-2.6.32-220.el6.s390x]

image=/boot/vmlinuz-2.6.32-220.el6.s390x

ramdisk=/boot/initramfs-2.6.32-220.el6.s390x.img

parameters="root=/dev/disk/by-path/ccw-0.0.0100-part1 rd_NO_LUKS rd_DASD=0.0.0300 rd_NO_MD  KEYTABLE=us SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_DASD=0.0.0100 rd_DASD=0.0.0101 rd_NO_LVM rd_NO_DM LANG=en_US.UTF-8"

Step 7 重新加载配置文件

[root@zLINUX~]# zipl -V

Using config file '/etc/zipl.conf'

Target device information

Device..........................: 5e:00

Device name.....................: dasda

Device driver name..............: dasd

DASD device number..............: 0100

Type............................: disk partition
