--- Comment #13 from marcus@blazingdot.com ---
> Currently only 'compression=lz4' comes to my mind.

It would surprise nobody if turning on compression caused problems.

If it's any consolation, here are the default locally set flags on the swap
zvol on a Solaris 10 machine:

rpool/swap  volsize               4G                     local
rpool/swap  checksum              off                    local
rpool/swap  compression           off                    local
rpool/swap  refreservation        4G                     local
rpool/swap  primarycache          metadata               local
