BTW, I am on the SCST mailing list (SCST is what open-e uses for iscsi and fibre channel targets), and it looks like Vlad, the main SCST developer, has done a short review of the persistent reservation code code that open-e's engineers submitted. Most of his comments are regarding coding style improvements (ie not using // comments), but he had some architectural improvements' too. This makes SCST the only linux iscsi target that works with Win 2008 clustering, unless LIO has made considerable progress. This means that it might draw more developers into developing SCST. So, there are improvements in the works!
