> I have a FreeBSD 10 server setup, with a 300G iSCSI target backed by a zVOL device.  With a windows 8.1 Workstation as the initiator connected to it.  I am trying to use it to store VMware Workstation Virtual Machines.  However I am having all kinds of crashes of Virtual Machines and file corruption with it.  I have found these errors on the Server, I setup a Virtual Machine on the workstations local disk, and have had no problems.

This is normal.  It's basically that CTL doesn't implement some optional
SCSI stuff.

> I am fairly new to using iSCSI on FreeBSD as a target I have ran it as initiator connecting to our Lefthand Networks SAN at work, but of course that was with the older iSCSI prior to 10.  I am kind of clueless on how to go about trouble shooting this issue.  Perhaps I did something stupid when I setup the configuration, which is shown below.

First, can you take a look at logs at both sides?  Is there anything
unusual?

Second, could you try to remove "blocksize 4k"?  I've seen some strange
behaviour with 4k blocks under ESX.
