Hello,

Sounds like ZFS does not correctly import cache and spares by label.

Example :

# zpool add home cache label/G12000KU2RVJAch
# zpool add home spare label/G1207PFGPTKDXhm=20
# zpool status home
  (...)
  home                       ONLINE       0     0     0
    mirror-0                 ONLINE       0     0     0
      label/G1203PGGLJWZXhm  ONLINE       0     0     0
      label/G1204PHKXHJ2Xhm  ONLINE       0     0     0
  (...)
  logs
    mirror-2                 ONLINE       0     0     0
      label/G12000KU2RVJAlg  ONLINE       0     0     0
      label/G12010KU22RVAlg  ONLINE       0     0     0
  (...)
  cache
    label/G12000KU2RVJAch    ONLINE       0     0     0
  spares
    label/G1207PFGPTKDXhm    AVAIL

# zpool export home
# zpool import -d /dev/label/ home
# zpool status home
  (...)
  home                       ONLINE       0     0     0

Did I miss something ?

Thank you very much !
