Of course you cant. You have labeled a disk that is already in use so in
turn the label should

Hi guys,
I second what others have said - crap.
But there could be some hope, not sure.
Can you check what is the actual size used by the pool on the disk?
It should be somewhere in zdb -C output (asize?).
If I remember correctly, that actual size should be a multiple of some rather
large

I have an 8-drive ZFS array consisting of WD15EADS drives. One of my disks
has started to fail, so I got a replacement disk. I have replaced a disk
before by:
zpool offline tank /dev/da5
shutting down, swapping from old disk to new disk
booting
zpool replace tank /dev/da5
This worked fine.

So you think it's because when I switch from the old disk to the new disk,
ZFS doesn't realize the disk has changed, and thinks the data is just
corrupt now? Even if that happens, shouldn't the pool still be available,
since it's RAIDZ1 and only one disk has gone away?

The data on the disks is not irreplaceable so if I lose the array it isn't
the end of the world but I would prefer not to lose it as it would be a pain
to get all of the data again.
Freddie's explanation is reasonable, but any ideas why it didn't happen when
I replaced my first dead drive (da5)?
I forgot to ask in the last email, is there a way to convert from Z1 to Z2
without losing data? I actually have far more storage than I need so I'd
consider going to Z2.

No, unfortunately it's not currently possible
I'm nervous to trust the hotswap features and camcontrol to set things up
properly, but I guess I could try it. When I first set the system up before
I put data on the array I tried the hotswap functionality and drives
wouldn't always re-attach when reinserted, even if I fiddled with
camcontrol,

Well thank you very much Western Digital for your absolutely pathetic RMA

done; I'm going to insist on these 00R6B0 drives being sent back, and being
