Is it possible to use a hard drive cloning utility to clone the linux ESX (3.5) partition? I am looking to upgrade to a larger drive, but before doing so, i'm curious if it's possible to do this.
If so, for those that have done this... were there an adverse effects?
Any information is greatly appreciated.
You mean the VMFS datastore? I imagine you can probably do this, but none of the cloning utilities are going to have support for VMFS, so you'll have to do a bit-by-bit copy of the datastore. This means that said utilities won't be able to resize the partition and filesystem, so you'll need to do this in ESX after you clone the data over to the new drive.

Welcome to the forums,
if you mean, the ESX environment, then yes just use ghost, PQ magic or your cloning tool of choice., if you mean VMFS (the partition that hosts the VMDK files) then you are out of luck, there are currently no thirdparty disk copy tools that understand the VMFS partition layer.

A bit-by-bit copy of the disk should still work - Ghost is able to do this, even with partition tables that it doesn't understand.
Interesting, I will have to try this, do you know if the copy if forensically sound?

Yes, I believe it is forensically sound - I've done it with various odd Linux partitions that Ghost doesn't understand as a filesystem and isn't able to mount and clone that way. I was able to clone a few servers this way and they ran fine.
Hello,
Actually this depends on how it was done. It is forensically sound for defined partitions. But if there is unused/unassigned space on the drive it would not be copied and that is what forensics also requires.
