P2V destination doesn't support files of this size
-
I'm trying to P2V a system and I'm getting a message
Error: The file system on 'Datastore1' does not support file this large. Please check the file system block size.
OK I'm guessing that the block size I choose 5+ years ago doesn't support 500+ GB VHDDs.
What are my choices?
Do I have to backup all my current VMs the reformat the datastore with a larger block size to be able to P2V this system?
-
Instead of guessing, can you look and see how the datastore is formatted?
I know I have never specified this information for either Hyper-V or VMWare. I always just take defaults. I have had > 500GB disks, in the past on VMWare. Initial 5.0 release I believe.
-
In vCenter I can see it VMFS 3.33, but I can't find what block size I set it at, can't find the setting.
-
According to this it appears that VMFS-5 will support larger files. Perhaps an upgrade is the best option? Of course, only after ensuring all backups are good.
-
I have 4-6TB Disks with VMFS-5
I'd upgrade.
-
Definitely time for an upgrade
-
Anyone ever have an upgrade go badly?
Specifically talking about converting VMFS from 3 to 5.
-
Take a backup, of course!

It is only a file system change, so while there is storage risk there is not essentially any system level risks, if that makes sense. The risk here is pretty much that the files corrupt in the process (or the entire filesystem does.) It should be extremely reliable but should anything go wrong, there is essentially no concern around the platform not continuing to work and so a restore is all that would be needed.
