I don’t see anything unusual here: zpool didn’t kick out the disk
because the disk was still there (so not `UNAVAIL`) and apparently
there were no read/write/chksum errors found yet. A scrub could’ve
made those clear though but until then: a slow disk is no reason for
zpool to kick it.

Then, the partitioning: author could’ve added `ada3` in its entirety
to the zpool, as long as it was a valid geom provider. The fact that
he chose to create multiple partitions on the disks has nothing to do
with zpool.

My point is: when I started reading the article, it struck me as an
article that would show me some weird quirk about zpool and why it
didn’t allow to replace a disk against all logics and/or
documentation. In the end: this is exactly how I expected it to be
replaced!

There are other off things about the article which I [lay out here](ht
tps://www.reddit.com/r/freebsd/comments/cbvqbt/replacing_a_silently_fa
iling_disk_in_a_zfs_pool/etizk0b?utm_source=share&utm_medium=web2x).
But it seems the OP had the last laugh, as it was just another karma
whoring endeavour from them.  There was no interest in the value or
quality of the content.
