I'm not aware of any TB+ drives available w/ 512b sectors. An RMA by HGST of a 512b drive got me a 4kb sector replacement. I was informed that getting a 512b sector replacement drive was not possible. My experience is that except for small drives, 512b sector drives are already unobtainable.
I think the issue Alexander encountered is in part the result of drives lying to the installer. In looking at my notes from installing oi151a7 on an N40L I seem to have had trouble w/ the text installer. Ultimately I succeeded using the LiveDVD GUI installer by installing to a small temporary partition, then manually creating a partition on another disk, forming a mirror and after it silvered, breaking the mirror and redoing the first partition and reforming the mirror. However, in reading my notes it appears that I may have used a 512b disk for the initial install, edited sd.conf, formed a pool on a partition of the 4kb disk, formed the mirror and then removed the 512b disk and replaced it w/ a 4kb disk. Unfortunately my notes are ambiguous. I was also doing battle w/ the 4kb HGST drive on my Sol 10 system and having other entertainment w/ a 4kb USB drive. I remember feeling pretty beat up by the time I was done. I got things as I wanted them, but it was quite painful. format(1m) would create partitions which were not sector aligned. or complain that they weren't when they were. It *can* be done, but forcing correct alignment of the pool can be difficult. I *really* wish one could just tell zpool to ignore what the disk says and force ashift=12 or whatever is desired. I hope this offers some clues. Reg -------------------------------------------- On Sun, 3/23/14, Richard Elling <[email protected]> wrote: Subject: Re: [discuss] rpool -- ashift=12 possible?

I believe your analysis is faulty. There is no way to force a pool to 512 or 4k. If the pool is 512, then that is the reported phys block size at the time. -- richard > Ok, new installation going to CLI and instert: > ,-----[sd.conf]----- > | sd-config-list = > | "ATA Samsung SSD 840 ", "physical-block-size:8192", > | "ATA Kingston SS200S3", "physical-block-size:4096"; > `------------------- > Exit CLI and follow the standard installation procedure with 'F2'. > After reboot from SSD I get a warning on Console: > ,-----[CLI]----- > | WARNING: Disk, '/dev/dsk/c3t0d0s0', has a block alignment that is > | larger than the pool's alignment > `------------------- > rpool ist not what I want. > root@arche:~# > root@arche:~# zdb | egrep 'ashift| name' > name: 'rpool' > ashift: 9 > When deleting the upper entry in sd.conf no Message appear any more. > > Question: > Must rpool set ashift=9 independent on the drive? > Depends on the omnios installer? > Is there a way to install rpool with ashift=12 or 13? > > Thx in advance. > -- > Best Regards > Alexander > März, 23 2014 > > > > ------------------------------------------- > illumos-discuss > Archives: https://www.listbox.com/member/archive/182180/=now > RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175743-23d1427b > Modify Your Subscription: https://www.listbox.com/member/?&; > Powered by Listbox: http://www.listbox.com ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/23998448-902cecc3 Modify Your Subscription: https://www.listbox.com/member/?&; Powered by Listbox: http://www.listbox.com ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
