给虚拟机添加新的磁盘分区
简单记录一下给虚拟机添加新的磁盘分区的步骤. 下面就可以启动虚拟机. 登陆到虚拟机,切换到root用户： [root@yangtk ~]# df -k Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-LogVol00 3142384 2963560 16624 100% / /dev/sda1 101086 10876 84991 12% /boot /dev/mapper/VolGroup00-LogVol03 8919192 6665924 1792880 79% /data tmpfs 257800 0 257800 0% /dev/shm /dev/mapper/VolGroup00-LogVol02 1015704 34452 928824 4% /tmp [root@yangtk disk]# cd /dev/disk/by-path [root@yangtk by-path]# ls -l total 0 lrwxrwxrwx 1 root root 9 Oct 21 06:00 pci-0000:00:07.1-ide-0:0 -> ../../hdc lrwxrwxrwx 1 root root 9 Oct 21 06:00 pci-0000:00:10.0-scsi-0:0:0:0 -> ../../sda lrwxrwxrwx 1 root root 10 Oct 21 06:00 pci-0000:00:10.0-scsi-0:0:0:0-part1 -> ../../sda1 lrwxrwxrwx 1 root root 10 Oct 21 06:00 pci-0000:00:10.0-scsi-0:0:0:0-part2 -> ../../sda2 lrwxrwxrwx 1 root root 9 Oct 21 06:00 pci-0000:00:10.0-scsi-0:0:1:0 -> ../../sdb [root@yangtk by-path]# fdisk /dev/sdb -l Disk /dev/sdb: 2147 MB, 2147483648 bytes 255 heads, 63 sectors/track, 261 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/sdb doesn''t contain a valid partition table [root@yangtk by-path]# fdisk /dev/sdb (进行分区) Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel.
