Replacing a faulty drive from a raidz2 array

[Discolai]

I have a raidz2 array of 6 x 4tb wd reds. One of the drives are now reporting smart failures so I contacted the retailer for an rma. They would like me to send in the drive for evaluation and repair.
Freenas would report the array as degraded when I remove the drive, but would it be fine to run it like this until I get my replacement?

I wouldn't recommend it to anyone, but it would be fine as long as you don't have anything else going wrong.
We usually suggest that having a pre-tested spare, that would allow you to swap the drive out, then send the bad drive out for replacement.
