Esxi disk space

Hi,

We have recently performed an upgrade of our Esxi server from 4.1 to 5.1 in order to unlock some more space on the virtual hard drives (256Gb limit).

I was expecting that after the upgrade, I would be able to increase the drive size from 256Gb up to 2Tb (space permitting) - however, the 256Gb limit is still there.

Do I need to provision a fresh virtual hard drive within this VM to access the new limit?

Or am I stuck with this limitation unless I provision a whole new VM?

Thanks.

Your Block Size on the VMFS partition is still 1MB. Upgraded datastores still use the old block size.

ESXi 4.1 Blocksizes.

• 1MB block size – 256GB maximum file size
• 2MB block size – 512GB maximum file size
• 4MB block size – 1024GB maximum file size
• 8MB block size – 2048GB maximum file size

The only way to overcome this issue, is to move the VMs off, the datastore, remove the datastore (delete it), and re-create the new VMFS-5 datastore. This will then give you a new 1MB (ESXi 5.0) block size which can support virtual machine disks up to 2TB-512bytes.

Are there any work arounds?  Was hoping to not have to delete my entire datastore - which would mean attaching some kind of external drive to temporarily move everything on to?
