[zfs-discuss] What would be the best tutorial cum reference doc for ZFS
as used on Illumos? I've seen a few tutorials written by people who obviously are very action oriented; afterwards you find you have worn your keyboard down a bit and not learned a lot at all, at least not in the sense of understanding what zfs is and what it does and why things are the way they are. I'm looking for something that would make me afterwards understand what, say, commands like zpool import ... or zfs send ... actually do, and some idea as to why, so I can begin to understand ZFS in a way that allows me to make educated guesses on how to perform tasks I haven't tried before. And mostly without having to ask around for days on end. For SOME part of zfs I'm already there, but only for the things I had to do more than twice or so while managing the Swedish lab at Sun Micro. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Question on 4k sectors
I think the problem is with disks that are 4k organised, but report their blocksize as 512. If the disk reports it's blocksize correctly as 4096, then ZFS should not have a problem. At least my 2TB Seagate Barracuda disks seemed to report their blocksizes as 4096, and my zpools on those machines have ashift set to 12, which is correct, since 2¹² = 4096 You cannot mix 512 and 4096 byte blocksize disks in one pool, at least not in a mirror. All disks in a single pool should have the same blocksize. There is a hacked version of zpool for OpenIndiana that has a blocksize option to the create subcommand. I don't know if other OSes have similar fixes. Such a hacked zpool might not be useful for the root pool at install time, at least it would require some subterfuge to make the installation use the correct blocksize, since the process is a bit too far automated.

Is the problem with ZFS supporting 4k sectors or is the problem mixing 512 byte and 4k sector disks in one pool, or something else? I have seen alot of discussion on the 4k issue but I haven't understood what the actual problem ZFS has with 4k sectors is. It's getting harder and harder to find large disks with 512 byte sectors so what should we do?

On x86 on zfs cyl 0 must be left out of zfs root pools. Been there.

Re: [zfs-discuss] Migrating 512 byte block zfs root pool to 4k disks
I suppose I must start by labelling the new disk properly, and give the s0 partition to zpool, so the new zpool can be booted?
