HINT: probably your BlockSize was choosen to low when creating the VMFS3 volume.
With the blocksite comes the max filesize.
Block size Maximum disk capacity
ps: Award points if you find answers helpful. Thanks.
You are right about the block size.
Now is there a way for me to increase it?
You can modify the blocksize of a LUN, but only by reformatting. Obviously, this means everything will be lost on that LUN. Otherwise, you will have to span the .vmdk file across multiple LUNs.

Reformat your VMFS with the block size you need to get to your max file size.
-Add Datastore, after you name it, you select the block size. Easy to move quick and miss it.
You cannot "increase" an existing vmfs to a larger block size if that is what you're wondering.
the block size can only be set before you format the LUN.
So you have to backup all the data of that specific LUN before reformatiing it.

I am experiencing the same issue. my only problem is that I gurrently have data on the storeage unit already and can not migrate them to another disk.
Well, theres no real way around it. Find another disk to backup to (or use Amazon S3 or something).
Thanks. I just want vmware to know we are not happy about this. I believe another option needs to be look at.
