What version of ESX are you using?? Even a 100MB block size is not valid. In vSphere 4.X, only block sizes avaialble are 1, ,2 4 and 8MB and in vSphere 5, there is only 1 block size of 1 MB. can you attach logs??

Are you connected to vCenter Server when you see this odd block size? If yes, is it the same when you connect the vSphere Client directly to the host?

If it is the same when connected to a host directly, then it might be an issue with the VMFS file system and you should consider to immediately open a call with VMware and/or run backups to minimize the risk of data loss.
