Linux6.4虚拟机环境安装了Oracle 11g R2,在RMAN的时候,扩展了快速恢复区,导致空间不够用,所以在VMware Workstation中给虚拟机加了一个10G的硬盘。再挂载到虚拟机中,记录,备用!
1.在VM虚拟机中添加好硬盘,重启虚拟机
2.root用户登录到虚拟机,查看磁盘情况
[root@grainliu /]# cd ..[root@grainliu /]# fdisk -l
Disk /dev/sda: 21.5 GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00069687
Device Boot Start End Blocks Id System/dev/sda1 1 262 2097152 82 Linux swap / SolarisPartition 1 does not end on cylinder boundary./dev/sda2 * 262 2611 18873344 83 Linux
Disk /dev/sdb: 21.5 GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0xc63ae59b
Device Boot Start End Blocks Id System/dev/sdb1 1 2610 20964793+ 83 Linux
Disk /dev/sdc: 10.7 GB, 10737418240 bytes255 heads, 63 sectors/track, 1305 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00000000
查出/dev/sdc是新加的大小为10G的磁盘
3.对磁盘进行分区处理
[root@grainliu /]# fdisk /dev/sdcDevice contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding a new DOS disklabel with disk identifier 0x6c49e48e.Changes will remain in memory only, until you decide to write them.After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u').

Command (m for help): wThe partition table has been altered!

4.查看分区加载的情况
[root@grainliu /]# fdisk -l
Disk /dev/sda: 21.5 GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00069687
Device Boot Start End Blocks Id System/dev/sda1 1 262 2097152 82 Linux swap / SolarisPartition 1 does not end on cylinder boundary./dev/sda2 * 262 2611 18873344 83 Linux
Disk /dev/sdb: 21.5 GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0xc63ae59b
Device Boot Start End Blocks Id System/dev/sdb1 1 2610 20964793+ 83 Linux
Disk /dev/sdc: 10.7 GB, 10737418240 bytes255 heads, 63 sectors/track, 1305 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x6c49e48e
Device Boot Start End Blocks Id System/dev/sdc1 1 1305 10482381 83 Linux
/dev/sdc1为新加载的区
5.格式化新的分区
[root@grainliu /]# mkfs -t ext3 /dev/sdc1mke2fs 1.41.12 (17-May-2010)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)Stride=0 blocks, Stripe width=0 blocks655360 inodes, 2620595 blocks131029 blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=268435456080 block groups32768 blocks per group, 32768 fragments per group8192 inodes per groupSuperblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632

格式化完成
6.在根目录下创建目录,将新分区加载到创建的目录下
[root@grainliu /]# mkdir /u02[root@grainliu /]# lsbin boot cgroup dev etc home lib lib64 lost+found media misc mnt net opt proc root sbin selinux srv sys tmp u01 u02 usr var
[root@grainliu /]# mount /dev/sdc1 /u02
7.验证是否挂载
[root@grainliu /]# df -kFilesystem 1K-blocks Used Available Use% Mounted on/dev/sda2 18577148 12856908 4776576 73% /tmpfs 771488 72 771416 1% /dev/shm/dev/sdb1 20635700 3016928 16570536 16% /u01.host:/ 157593596 99913120 57680476 64% /mnt/hgfs/dev/sdc1 10317828 154232 9639480 2% /u02
8.设置开机自动挂载
[root@grainliu /]# vi /etc/fstab
## /etc/fstab# Created by anaconda on Wed Jun 19 06:44:20 2013## Accessible filesystems, by reference, are maintained under '/dev/disk'# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info#UUID=55f9330b-f964-4efe-8949-e4a080a9bc02 / ext4 defaults 1 1UUID=2bdf0c98-5a08-421b-8375-421fed017ca3 swap swap defaults 0 0tmpfs /dev/shm tmpfs defaults 0 0devpts /dev/pts devpts gid=5,mode=620 0 0sysfs /sys sysfs defaults 0 0proc /proc proc defaults 0 0/dev/sdb1 /u01 ext3 defaults 0 0/dev/sdc1 /u02 ext3 dufaults 0 0
保存,退出。
