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?
Yes. See the ZFS Admin Guide section on Designating Hot Spares inYour Storage
Pool.

Yes, thatnk. I've read that, but the guide and its examples
only refer to hot spares for a certain single pool, except
in the starting phrase: "The hot spares feature enables you
to identify disks that could be used to replace a failed or
faulted device in one or more storage pools. "
Further on in the examples, hot spares are added to specific
pools, etc.
Can the same spare be added to several pools?
So far it is a theoretical question - I don't have a box with
several pools and a spare disk in place at once, which I'd
want to sacrifice to uncertain experiments ;)
