No, the devices will all be created with the same size in the kernel. The size check is solely enforced in userland. > 2. What about my case - why format() or EMC's inq (and Symmetrix > itself) show that all these devices are the same size while > fstat() shows different? There are some oddities w.r.t. specfs, devices, and size determination. We play some tricks in zpool, such as keeping the device node open, to try and get a reliable device size. But my understanding is that it's still possible to get the wrong answer for some devices. I would suggest doing a 'truss -v fstat -t open' and see what the actual values being returned are. - Eric -- Eric Schrock, Solaris Kernel Development http://blogs.sun.com/eschrock _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
