One of my hard drives in a RAIDZ2 is dying.

1. What’s the proper way to replace it?

2. Is it safe to keep a RAIDZ2 pool online while removing a faulty drive?

   3. Seagate no longer offers advance replacement and I don’t have a spare on hand. Is it safe to remove the failing drive and run the pool degraded for 7–10 days?

That's a risk only you can decide to take.

Im not sure that applies to a zfs raidz2 pool does it? When replacing a single disk in a multi-disk pool like that.

They would want to offline the bad disk, remove it, and import a new disk and re-silver it. I dont know the technical steps to advise.
