Solved Convert UFS SSD into ZFS - dump & restore?

[lib13]

Hi,

I've never played with ZFS.
Right now, I have a UFS SSD with boot and system files, as well as some virtual machines, and two big spin hard disks for storage of data files in UFS, as well.
But I'm thinking to change the file system for the SSD to ZFS.

What's the best way to do this? Are dump(8) and restore(8) good tools for this task? If so with what parameters?
If not, what do you recommend? rsync(1), cp(1), cpio(1), tar(1), pax(1)?

restore(8) won't work with ZFS. I recommend using rsync in this manner to back up every file with preserved attributes.

restore(8) won't work with ZFS.

I don't think so. Surely dump(8) will not work on ZFS, but I see no reason to belive that restore would fail. Restore works completely in user code, it will not directly mess with the file system but only create the files contained in the dump. Anyone who tested this, please pipe in. I would at least try it.

It's worth testing restore(8). I suspect it will work. So will rsync(1), given enough options to handle links.

The others I would only use if I were familiar with them. For that matter, sysutils/cpdup might be worth a try.
