I just had an email exchange with support. There is no support for iSCSI and Windows 2008 clusters with any Open-E product, and no date on when it will be supported (just a "be patient").

Looking around a bit it seems that the Linux iSCSI target packages (IET, etc.) do not support SCSI-3 persistent reservations which Windows 2008 needs. Feels like this may take a while since the open source base Open-E uses doesn't support it...

Unfortunately I'm facing pulling out the Open-E DOM and re-installing Windows with StarWind on it...
