Losing access to Scratch Partition vSphere 5

I have a question in regards to ESXi 5.0 Update 1:

I originally installed ESXi 5.0 on a USB flash drive for our hosts, and then configured a datastore to be used for the scratch partitions of all the hosts.  Now, I want to expand the datastore, but am concerned if the hosts lose access to the Scratch partitions if something goes wrong, and what would happen if all of sudden the datastore housing the Scratch partitions was unavailable to the hosts.  PSOD?

Has anybody had this happen?

Is it safe to expand the VMFS partition with active guests using the datastore?  I've migrated everything off but the scratch partitions, but am curious as to the answer.

Thanks,

Yes, we expand VMFS partitions, with active VM Guests. (but we always ensure we have valid backups before any configuration change to datastores).

Scratch partition is used for logging, if unavailable, the host will not crash.
