Degraded RAIDZ2 but cannot find the failed disk

in flag

I'm not too experienced with raid and ZFS things, and here's what I encounter.

A raidz2 array was showing degraded status. One disk states unavail and says that it was /dev/da3p2. Strangely enough, another disk detected as da3 is showing online and having no issue. So, my first question is: How is this possible? da3p2 is a partition of da3. How can the disk (da3) be part of the array, instead of the partition (da3p2)?

So I assumed that I need to replace da3. Was I wrong here?

Before disk replacement:

After replacing the disk, da3 is now become da17p2 yet the array is still degraded showing da3p2 OFFLINE.

zpool status:

root@thamar[~]# zpool status -v Volume1
  pool: Volume1
 state: DEGRADED
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

I am also unable to find any info on that 7659882188769969497 disk. So, how do I find it and get it replaced?

This issue lasts for weeks now, no one can figure out that mysterious da3p2.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
