Increasing the disk space in vCenter Server Appliance 5.x

vcenter5.5 Appliance의 disk 용량 부족으로 시스템이 문제가 발생할수 있다.

Disk추가로 문제를 해결할수 있다.

Disk를 추가한다.

1.  vCenter Server Appliance 를 셧다운
2. 스냅샷 생성
적당한 용량의 Disk를 추가한다. 
3. vCenter Server Appliance의 전원을 켠다.
4. Connect to the vCenter Server Appliance using SSH.
5. 디바이스 ID를 확인한다. 
   fdisk -lu
   
   Note: By default, the device ID for the new disk is /dev/sdc
   
   
6. Access the disk utility for the new disk by running this command:
   
   fdisk /dev/sdc
   
   
   1. Press N then Enter for new partition
   2. Press P then Enter for primary partition
   3. Enter 1 as the partition number
   4. Accept the default start block and the default end block
   5. Enter W to write the partition table to disk
   6. Create a new partition on the new disk:
      
      
7. Build an ext3 file system on the new disk using this command:
   
   mkfs -t ext3 /dev/sdc1
   
   
8. Create a new temporary directory under the root directory by running this command:
   
   mkdir /tmp/db
   
   
9. Mount the new disk to the /tmp/db directory by running this command:
   
   mount -t ext3 /dev/sdc1 /tmp/db
   
   
10. Power off all services that access the vPostgres /storage/db directory by running this commands:
    
    service vmware-vpxd stop
    service vmware-vpostgres stop
    service vmdird stop
    service vmware-inventoryservice stop
    
    
11. Copy all the /storage/db files into the /tmp/db directory by running this command:
    
    cp -a /storage/db/* /tmp/db
    
    
12. Return to the root directory by running this command: 
    
    cd /
    
    
13. Verify the mount points by running this command:
    
    mount
    
    For example, you see output similar to:
    
    /dev/sda3 on / typ ext3 (rw)
    proc on /proc type proc (rw)
    sysfs on /sys type sysfs (rw)
    udev on /dev type tmpfs (rw,mode=0755)
    tmpfs on /dev/shm type devpts (rw,mode=0620,gid=5)
    /dev/sda1 on /boot type ext3 (rw,noexec,nosuid,nodev,noacl)
    /dev/sdb1 on /storage/core type ext3 (rw,nosuid,nodev)
    /dev/sdb2 on /storage/log type ext3 (rw,nosuid,nodev)
    /dev/sdb3 on /storage/db type ext3 (rw,nosuid,nodev)
    /dev/sdc1 on /tmp/db type ext3 (rw,nosuid,nodev)
    
    
    
14. Unmount the original disk and the new disk by running these commands:
    
    umount /dev/sdb3
    umount /dev/sdc1
    
    
15. Mount the new disk to the /storage/db directory by running this command:
    
    mount -t ext3 /dev/sdc1 /storage/db
    
    
16. Preserve the new mount to the /storage/db directory by running the command:
    
    sed -i -e 's#/dev/sdb3#/dev/sdc1#' /etc/fstab
    
    Note:  Do not remove /sdb3 from the virtual machine.
    
    
17. Reboot the vCenter Server Appliance.
