Clicking expand pool causes raid downgrade

[Fern]

I wasn't going to expand the zfs array. I'm just experimenting and clicking around.

SystemInfo
Truenas: TrueNAS-SCALE-24.04-BETA.1
CPU: i3-8100
RAM: 32G

ZFS ARRAY
4*6T RAID-Z2 with SLOG SSD

ISSUES
When I clicked the expand next to the pool (I didn't know what expand meant)
[EFAULT] Command partprobe /dev/sdf failed (code 1): Error: Partition(s) 1 on /dev/sdf have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes.

This happened and I saw my RAID-Z2 has become RAID-Z1 with one un-assigned disk pops up. But ZFS Health didn't tell me anything wrong. After I rebooted the system the ZFS Health started to tell me my array had been downgraded. After that, I clicked that again and the same problem popped up. But this time my LOG drive became un-assigned.

After all that my data on that pool wasn't lost. But can I repair it back to RAID-Z2?

Damn, I just realize that I wasn't doing raid-z2 at the start!!!!

I just raidz1 from start to end! But the drive offline issues persist!

I recreate the pool and click that button again and I have more depth info about this
