ESXI中centos6.8扩展新增磁盘

1、在EXSI中新增磁盘

1.1、打开虚拟机属性窗口，点击添加
1.2、选择磁盘，点击下一步

1.3、选择创建新的虚拟磁盘

1.4、调整要新增的磁盘大小

1.5、后面一下步、完成。

 

2、在centos中挂载磁盘

2.1、查看新增的磁盘是否被系统识别

 

[root@bogon u01]# fdisk -l

Disk /dev/sda: 53.7 GB, 53687091200 bytes
255 heads, 63 sectors/track, 6527 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0008b1b1

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          64      512000   83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2              64        6528    51915776   8e  Linux LVM

Disk /dev/mapper/VolGroup-lv_root: 49.0 GB, 48997859328 bytes
255 heads, 63 sectors/track, 5956 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000


Disk /dev/mapper/VolGroup-lv_swap: 4160 MB, 4160749568 bytes
255 heads, 63 sectors/track, 505 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

2.2、如果查看结果，没有新增的磁盘/dev/sdb，则执行下面操作，再执行fdisk -l，新增磁盘会出现。

 

[root@bogon dev]# ls /sys/class/scsi_host/
host0  host1  host2
[root@bogon dev]# echo "- - -" > /sys/class/scsi_host/host0/scan 
[root@bogon dev]# echo "- - -" > /sys/class/scsi_host/host1/scan 
[root@bogon dev]# echo "- - -" > /sys/class/scsi_host/host2/scan 

2.3、格式化新增磁盘

[root@bogon dev]# mkfs.ext4 /dev/s
scd0      sda1      sdb       sg1       shm/      sr0       stdin     systty    
sda       sda2      sg0       sg2       snapshot  stderr    stdout    
[root@bogon dev]# mkfs.ext4 /dev/sd
sda   sda1  sda2  sdb   
[root@bogon dev]# mkfs.ext4 /dev/sd
sda   sda1  sda2  sdb   
[root@bogon dev]# mkfs.ext4 /dev/sdb
mke2fs 1.41.12 (17-May-2010)
/dev/sdb is entire device, not just one partition!
无论如何也要继续? (y,n) y

This filesystem will be automatically checked every 33 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

 2.4、挂载新增磁盘

[root@bogon dev]# mkdir /u02
[root@bogon dev]# mount /dev/sdb /u02

 2.5、查看新增的磁盘，有/dec/sdb /u02就算成功

[root@bogon dev]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
                       45G  3.1G   40G   8% /
tmpfs                 1.9G     0  1.9G   0% /dev/shm
/dev/sda1             477M   39M  413M   9% /boot
/dev/sdb              886G   72M  841G   1% /u02
