Hi, I just created a 10TB LUN with latest git for tgtd. And the initiator can successfully see that the disk is 10TB. Using ServiceActionIn/ReportCapacity16 correctly. My system is a 64 bit system, is your box 32 or 64 bit? regards ronnie sahlberg On Sun, Oct 31, 2010 at 7:49 AM, Robert Lawrence <robert@xxxxxxxxxxxx> wrote: > I recently attempted an upgrade from tgtd 1.0.5 to tgtd 1.0.10 on a server > with several multi-terrabyte arrays, but after the upgrade all the linux > initiators started giving complaints about unsupported sector sizes. > > I setup a test server and initiator client to try to figure out the problem, > and found that some change between 1.0.6 and 1.0.7 caused the breakage.
