Hi,
I have been trying to use both FreeNAS 7 and FreeNAS 8 to provide iSCSI storage to a Windows Failover Cluster for use with Hyper-V. WFCS provides a special type of storage called Cluster Shared Volumes which enable Virtual machines to be move between cluster nodes "live". This requires that all nodes in the cluster can access the iSCSI volume simultaneously.
Unfortunately it apears that the iSCSI target used in FreeNAS does not fully support this.
Whilst the storage passes all the Cluster Validation tests and can be brought online once as a CSV, as soon as one node fails or you try to move the CSV to another node, the volume goes offline and cannot come back online. The only way to resolve the issue it to restart the iSCSI target.
The issue has been mentioned in the FreeNAS 7 forums:
http://sourceforge.net/apps/phpbb/freenas/viewtopic.php?f=53&t=8665
http://sourceforge.net/apps/phpbb/freenas/viewtopic.php?f=53&t=9367
which contain more details of the steps to re-create and the errors reported, however no-one has been able to suggest a fix up to this point :-(
I have also raised a bug report for this issue here:
http://support.freenas.org/ticket/322
If anyone from the FreeNAS 8 team is able to respond to this I would be happy to provide any additional information required or test new code/fixes?
Many thanks,
Nick.
