I just tested lv activation with a degraded raid1 thin pool.
Unfortunately it looks like activation mode=degraded only works for
plain raid1 lvs. If you add a thin pool, lvm won't activate it in
degraded mode. (Unless you specify --activationmode partial, which is
IMHO rather dangerous.)

Unfortunately I cannot even replace a faulty PV if a thin pool is present.

From you command history, I can see you are trying to remove the failed device (to re-add a good device later). Instead, can you try with lvconvert --repair or lvconvert --replace? Do they works?

Thanks.
