Congrats on the new job; my condolences on the funeral :(. > The INTEL drives are 512b sectors. The HGST drives (which are NOT > boot disks) have 4kb sectors. zdb shows this with ashift. Yes, they have 4k physical sectors. But do they have 4k or 512b logical sectors? My theory (and I guess somebody should just ask Toomas to sort it out by now :) ) is that loader is only broken for 4k drives that have 4k logical sectors too, not 4k physical sector drives that expose 512b logical sectors. What does # echo ::sd_state | mdb -k | egrep '(^un|_blocksize)' show for your drives? For my WD red drives, it's: un 19: ffffff133905b640 un_sys_blocksize = 0x200 un_tgt_blocksize = 0x200 un_phy_blocksize = 0x1000 un_f_tgt_blocksize_is_valid = 0x1 Which I believe indicates they have a physical sector size of 4k and a logical sector size of 512b. So they should work with loader. But I'm guessing Geoff's disks have both a physical *and* logical sector size of 4k, and *those* are the disks that are currently broken... _______________________________________________ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com http://lists.omniti.com/mailman/listinfo/omnios-discuss
