ZFS What does this zfs error mean?

[Tracker]

I'm trying to boot from a HDD with an SSD inside the laptop. One zpool is named backuppool (HDD) , other zpool is named zroot (SSD).

The SSD seemed to develop some zfs errors and I rsynced the data into the HDD. However there seems to be this error (see image) when I try to boot.

What does it mean and how does one fix it?

That looks like a hard read error from the SSD hardware.

Thanks. Any idea what's the best course of action here?

I had run basic hard disk tests on the SSD for a couple of hours (mentioned it on another thread in which you had replied) and things seemed ok with those hard drive tests.

Would it cause issues if I try to import this and affect the HDD as well?

I would copy this SSD/disk to another one while the rest of the data can still be read. Import readonly for the copy.
