Increasing the virtual disk size provided to a VM is straight forward (though be aware that snapshots need to be deleted 1st, if any exist)... | |||

The trick is to extend the logical partition | The trick is to extend the logical partition within the OS. Depending on the original partition type and the OS, the options vary. | ||
=== Increase Logical Partition === | |||
Generally boot or system disks cannot be extended whilst the OS is up, whereas normal data disk can be in later OS's, but this is still not ideal. Its generally most reliable to plan for system down time, and use a utility to extend the partition whilst its offline. Especially in a virtual environment there is no excuse for not making a backup of the partition 1st. | |||
For Windows 2008 machines this isn't a problem. | |||

=== VM's With Lots Of Disks === | |||
It can be very difficult to identify the correct disk within VMware to increase when a VM has a large number of VMDK's. | |||
* Disk numbering behalves differently, with Windows starting at Disk 0, and VMware starting a Disk 1 | |||
* SCSI ID's will match, but Windows SCSI bus numbers are normally 0, whereas VMware bus numbers will increment (so VM disk 35 (Win disk 34), could be 2:4 in VMware, but 0:4 within the OS) | |||
* Disk size can be a useful method of validation (if differing disk sizes are used) | |||
* Windows drive letters are useless, never assume D: is disk 2 for example | |||
