[zfs-discuss] zfs global hot spares?

Hello all,

  Is there any sort of a "Global Hot Spare" feature in ZFS,
i.e. that one sufficiently-sized spare HDD would automatically
be pulled into any faulted pool on the system?

  So far I saw adding hot spares dedicated to a certain pool.
And perhaps scripts to detach-attach hotspares between pools
when bad things happen - but that takes some latency (parsing
logs or cronjobs with "zpool status" output - if that does
not hang on problems, etc.)

  Are there any kernel-side implementations?
