corruption. Applications may be affected.

Yes, I did exacly as you wrote - removed the failed drive, installed a replacement drive, and issued a 'zpool replace' command.
I tried this way to:
I disabled running services in that pool, unmounted and mounted it again. Even I exported/imported that pool.
It has no readonly property.
Of course I have a backup.
