vSphere4 - drive size limit?

[SBaldridge]

I am running vCenter4 and have a NetApp SAN hosting a NFS share of 2TB usable. I am trying to extend an existing drive in a vanilla Win2003 32bit server from 850GB to 1.75TB using the vCenter GUI but I see an error: "a general system error occurred: internal error", as a test I increased it successfully to 1TB but I can't increase beyond that. This is on a ESX3.5 host. I realize that VMFS are limited by block size but what about NFS? What am I forgetting here?

I attached an image of the datastore in case you want to see.

Thanks!

Maximum VMDK size is still 2TB. Fill Support Request, it should not work this way.

Hello.

This might be a bit of a shot in the dark, but do you have ASIS or snapshots consuming any space on that volume. The NetApp forums are also awesome; You may want to post this over there, if you haven't already.

Good Luck!

Check the block size on your VMFS volume, that will limit individual file sizes. You can find it under "Formatting" in the datastore details on your storage configuration page in vCenter. If you click on "Properties...", it iwll tell you your max file sized in the "Format" section...

Thanks so far for the suggestions.

I am able to create another large drive on that NFS share and Netapp ASIS/Snapshots are not enabled on that particular volume. SInce I can create another drive I think the problem isn't on the NetApp side, I just can't extend the existing drive past 1TB. The drive has no VM snapshots.

re: Check the block size on your VMFS volume

I don't see that information on my NFS datastores, only on VMFS datastores.

Solution: The OnTap version on my Netapp 2020 filer isn't fully compatibel with ESX 3.5 so VMWare had me upgrade the host to 4 and the problem is solved.

Thanks for the suggestions.
