Question

Extending a virtual volume in CentOS

Asked by: DReade83

I have a XenServer installation. One of the VM's is running CentOS 5.4.

The VM has been extended in XenCenter from 12 to 16GB via the Storage tab whilst the VM was shutdown. I rebooted the VM but the virtual drive hasn't extended.

Do I need to do something to extend the drive?

The drive I want to extend is: /dev/mapper/VolGroup00-LogVol00

Any help much appreciated. Thanks in advance.

How to extend the partition size in Linux operating systems:

Linux operating systems supports many file system types (for example, ext3, xfs, reiserfs). To extend file systems on an extended disk you must use file system tools that correspond to a particular file system type. Recommended file systems are those that can be expanded while the system is running and mounted. For example:

      " If you use ext3: After resizing the disk in XenServer, start the operating system and use the resize2fs tool with the name of the partition that should be extended (refer to the manual for more details). For example:
      # resize2fs /dev/xvda1

      " If you use xfs: After resizing the disk in XenServer, start the operating system and use the xfs_growfs tool with the name of the partition that should be extended (refer to the manual for more details). For example:
      # xfs_growfs /dev/xvda1

      " If you use reiserfs: After resizing the disk in XenServer, start the operating system and use the resize_reiserfs tool with the name of the partition that should be extended (refer to the manual for more details). For example:
      # resize_reiserfs /dev/xvda1
