status: Some supported and requested features are not enabled on the pool.
        The pool can still be used, but some features are unavailable.

        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(7) for details.

Expand with the 4x 10TB drives directly below the existing 4 in das2. Add a new raidz2 zdev to the pool.

Command to add the drives:

zpool add storage-mass raidz2 -f \
    ata-WDC_WD101EMAZ-11G7DA0_VCH3B7NP \
    ata-WDC_WD101EMAZ-11G7DA0_VCGV78HP \
    ata-WDC_WD101EMAZ-11G7DA0_VCGPK5XP \
    ata-WDC_WD101EMAZ-11G7DA0_VCGV47VP

Test of the command (using -n for dry-run):

root@helios:~# zpool add storage-mass raidz2 ata-WDC_WD101EMAZ-11G7DA0_VCH3B7NP ata-WDC_WD101EMAZ-11G7DA0_VCGV78HP ata-WDC_WD101EMAZ-11G7DA0_VCGPK5XP ata-WDC_WD101EMAZ-11G7DA0_VCGV47VP -n
invalid vdev specification
use '-f' to override the following errors:
/dev/disk/by-id/ata-WDC_WD101EMAZ-11G7DA0_VCH3B7NP-part1 is part of potentially active pool 'Media'
/dev/disk/by-id/ata-WDC_WD101EMAZ-11G7DA0_VCGV78HP-part2 is part of potentially active pool 'Media'
/dev/disk/by-id/ata-WDC_WD101EMAZ-11G7DA0_VCGPK5XP-part2 is part of potentially active pool 'Media'
/dev/disk/by-id/ata-WDC_WD101EMAZ-11G7DA0_VCGV47VP-part2 is part of potentially active pool 'Media'
root@helios:~# zpool add storage-mass raidz2 ata-WDC_WD101EMAZ-11G7DA0_VCH3B7NP ata-WDC_WD101EMAZ-11G7DA0_VCGV78HP ata-WDC_WD101EMAZ-11G7DA0_VCGPK5XP ata-WDC_WD101EMAZ-11G7DA0_VCGV47VP -n -f
would update 'storage-mass' to the following configuration:

        storage-mass
          raidz2-0
            ata-WDC_WD101EMAZ-11G7DA0_VCG9YGZM
            ata-WDC_WD101EMAZ-11G7DA0_VCGAM7KM
            ata-WDC_WD101EMAZ-11G7DA0_VCGSDUGN
            ata-WDC_WD101EMAZ-11G7DA0_VCH2NUVP
          raidz2
            ata-WDC_WD101EMAZ-11G7DA0_VCH3B7NP
            ata-WDC_WD101EMAZ-11G7DA0_VCGV78HP
            ata-WDC_WD101EMAZ-11G7DA0_VCGPK5XP
            ata-WDC_WD101EMAZ-11G7DA0_VCGV47VP

The warning about pool Media is caused by the old ZFS configuration that these drives were apart of. The Media pool is no longer in use and is unrelated to the in-use storage-media pool. Due to this, the -f must be used (alternatively, the drives could be wiped).
