Volume still okay?

Hi together,
I'm pretty new to freenas. Yesterday I saw that my pool was degraded and found one deive that hat some read/write errors. So I planned to buy a new hard drive to replace it. But as i restarted the System, it began to resilver.
Looks like it was able to heal itself completely, I would observe the Nas in the following days, would you be more concerned and replace the disk anyway? Is it normal it only resilvered a few GB's? Pool is Raid-Z with 12 10TB drives...
(See zpool status attached)

Thanks in advance!

Yes. Your pool is OK again with all drives back.

But: I would reconsider your pool layout. Raid-Z1 with 12 10TB drives is really dangerous. If one drive completely fails and has
to be replaced the resilver of a drive that huge will last quite a time and put stress on your pool. If another drive fails during that
time your pool is gone.
