Hi everybody, so I did it. Three disks as a raidz pool, (zfstank), and created zfstank/var and zfstank/data
Set both mountpoints as legacy and put them into fstab - I know I could zfs deal with that, but I feel more comfortable that way. Restoring all the data from backup took a long time, but not as long as doing the backup in the first place. Write rate was, most of the time, impressive. In fact, so far it was a really painless experience. There was a hard lockup - and zfs recovered nicely. But it doesn't seem to react to 'sync' is that true or just a feeling?
