Strange disk id after replace it

TrueNAS General
1

Hello,
We use TrueNAS-13.0-U6.7 on HP Apollo 4200 (ProLiant XL420 Gen10 Plus)
We changed a disk in slot 13 : first OFFLINE, then attempt to replace with new disk (the exact same model) → failed, so start a scrub of the pool (as doc advised), the new attempt to replace → success, then resilvering of the data and finally the pool is now healthy (not anymore in degraded mode).

What is strange is the “ZFS” name of one disk. while all the disk names start with ‘gptid/XXX’, one disk was named ‘da13p2’.
Is this normal?
Could this be the source of a future problem?
As this is a production machine, I’m trying to anticipate future problems.

Unfortunately yes, in CORE that can happen. It happened to me and I was not pleased, I thought something was wrong too.

Nope. Not that I am aware of, and I have used this on SCALE as well.

I’m confused in what you are saying. The pools all look healthy from the data you provided.

As far as I can tell, you are good.

Thank you for your very helpful reply.
I provided the data after the disk was replaced and integrated in the pool, that’s why it appears as healthy.
