I have a problem with my box. The slog started showing errors, so I decided to
remove it. I have tried to offline it with the same result. Any ideas?
I have offlined the cache device, which happened immediately, but both
offline/remove of the slog hangs and makes the box unusable.
If I have a
How long have you let the box sit? I had to offline the slog device, and it
took quite a while for it to come back to life after removing the device
(4-5 minutes). It's a painful process, which is why ever since I've used
mirrored slog devices.

Hours... :-(
Should have used both devices as slog, but...
Thinking maybe I could make a mirror with the cache device and then remove
the failing disk?
I will give it a try.

It worked! Sort of... :-)
I had to remove the mirror - when I tried to break the mirror (detach) it
failed:
hellevik@xeon:~$ pfexec zpool detach master c8t5d0
cannot detach c8t5d0: no valid replicas
This is what I did, for reference:
It was suggested to me by Ian Collins, that doing zfs sends and
receives, can render a filesystem "busy".
if there isnt a process visible doing this via ps, I'm wondering how
one might check if a zfs filesystem or snapshot is rendered "busy" in
this way, interfering with an unmount or destroy?
