Failing to snapshot specific VM on VMWare datastore

[Henning Kessler]

Hello,

I have an issue with a VMWare snaphot producing constant errors for a single VM which is hosted on a iSCSI zvol on my FreeNAS.

"The following VM failed to snapshot mypool/iscsi@auto-20160414.1800-2w:
[iscsi] ELK/ELK.vmx"

I can do snapshots from the VM on the ESXI system without any errors. When try to do a manual snapshot from my FreeNAS system I can see on the ESXI host that the snaphot is made successfully on another VM but fails on the other with the following output:

Traceback:

What can I do?

Those errors should have been fixed by https://bugs.freenas.org/issues/6873, though the dev did note that further work is needed. If you decide to create another bug report at bugs.freenas.org, mention that one in it and post the new bug # here.
