[zfs-discuss] ZFS on single drive?

Can I suggest setting failmode to continue on the pool so it doesn't 
hang on failure.

Has anyone got any recommendations with that?

In the event of total disk failure I would feel that the data isn't as 
recoverable, but others opinions may differ. You should have backups 
anyway. I've had some pretty dead ext4 drives that I've managed to run 
ddrescue and retrieve a good portion of the data. I don't think you'd 
recover ZFS as easily. - But that said you should always have backups 
unless you don't care about your data.
