It only has 1 pending sector. If it’s still under warranty, yes, you can replace it likely they will do so with pending sectors. If it’s not under warranty, I likely would not for 1 bad sector as ZFS would have corrected it. I would however make sure you have ongoing smart tests, and, scrubs. Myself, I’d just monitor it for further issues. I can take a few pending sectors without worrying much about it. Assuming you have parity that is, like raidz(1-3) or a mirror?
If it’s running 24/7 with no spindown, that’s < 1 year old so should be warranted. However, I also note you have a load cycle count of 29,591 which is quite a bit in a year. My seagate with about the same number of hours of usage has a count of 2,597. Here is a reference thread if it’s the same issue:
Likely the count isn’t a problem at all for those types of drives, but you can check the rated lifetime for that drive with Seagate.
