Replaced drive - reports delete

[lastcmaster]

I had a 2GB Baracuda (ST2000DM001) that was starting to have more and more sectors in error so I replaced it with a new ST2000DM008. After that, this new drive show a delete operations at the same level as write.

These three disks are the one raidz-1 vdev.

Any ideas what this is? No other vdev in this or any of my other FreeNAS or FreeBSD systems show this.

It might be related to the disk being SMR, though still kind of strange, I usually observe higher read and write latencies, not delete, how was the resilvering speed?

It took about 48 hours to resilver the disk.

That's expected with SMR disks, my a little over half-filled 4TB SMR disks take around 3 and half days to resilver.

Thanks.
