ZOL FAQ proposes to use whole disk, therefore partitioning is not required. From the same reason, it is not neccessary to create a partition table (be it GPT or ms-dos compatible), ZFS will create it automatically.

However, it might still be useful to use a single partition, which is slightly smaller than the size of the disk. This is to allow for problems at the time of disk replacement (e.g. due to failure). Not all disk marketed as 2TB HDD are of the same size and it is not possible to replace a drive in ZFS's vdev with a smaller drive (even when smaller by a few sectors).

Merging with Installing Arch Linux on ZFS?

Does it make sense to keep two different articles? What about just add the sections about how-to add zfs packages to the installation media and the trouble shooting here?

Interesting. I think it could work, but I am not sure where to place it. The installing on zfs article is very long. Do you have any ideas? Demizer (talk) 03:24, 2 March 2013 (UTC)
I think most of the other article is actually wrongly placed. The information about the partition, formatting, and mounting are covered in the general installation guide, I am using zfs in a bios and efi system and I ignored it. What is really important is: adding zfs packages to the installation media, creating the pool and the fs for installation, and the kernel line to mount zfs root.

Max size of ZFS

On wikipedia ( http://en.wikipedia.org/wiki/ZFS )it is claimed that

A ZFS file system can store up to 256 quadrillion zettabytes (ZB)

This means to my understanding 256000 quadrillion exabyte. Here the claim is more moderate : 16 Exabyte. I suppose the difference comes from some 64/128 bit confusion and is of course more of theoretical interest. Michaelcochez (talk) 12:04, 15 July 2013 (UTC)

They aren't conflicting claims, they claim different things. Both the maximum file size on ZFS and the maximum volume size is 16EB, but the filesystem itself can be up to 256 quadrillion zettabytes. Kyrias (talk) 17:18, 21 August 2013 (UTC)
