[OpenIndiana-discuss] Illumos UFS vs FreeBSD UFS?

[Hung Nguyen Gia]

Are they compatible? Could I use UFS for data exchange purpose?

UFS is available on all BSDs, including one doesn't support ZFS. So it's a better portable FS than ZFS.

But I'm a bit pessimistic, because each BSD's UFS is different to the other. e.g: FreeBSD's UFS2 doesn't mountable under DragonflyBSD, which only supports UFS1.

So I don't expect much.

BTW, our UFS is UFS2 or UFS1 or something else?

Please let me know. Thanks.
