Pool is not healthy

[user000]

I was taking apart my NAS for maintenance. After reassembling it, one of my pools came back with 4 Checksum Errors on one drive.

I ran a Scrub, and it finished with 0 new errors, but the pool is still showing a Red/Unhealthy status because of those previous 4 errors.

I suspect I had a loose power connection during the first boot. How do I clear these old errors to get the pool back to a healthy green state?

There may be a way to do it from the GUI, but from the Linux shell;

sudo zpool clear FlashStorage01

In general, checksum errors are data cable problems. Though it could have been loose power cable.

thank you that did it.
