I recently got this alert:
"Pool SSDPool state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected."
I found the culprit directory, I can't delete it, but I could rename and move it so that it's not causing any major issue. Yet my cloud replication fails because of it.
I really wish the TrueNas doc and tutorial covered this type of stressful situation.
My system is very simple. Too simple for some of you, but I'm fine with it
The SSD seems to be healthy so far, don't you agree? What are my options? Do I delete only the one dataset and restore it from my USB drive? Or do I need to kill the pool completely and restore all the datasets to it? Can I trust the latest dataset snapshot that have been replicated since they contain this "corrupted_dir" folder? Will I need to redeploy all my applications (they all use host path)?
Thanks for your help.

Selective self-test flags (0x0):

The SSD seems to be healthy so far, don't you agree? What are my options? Do I delete only the one dataset and restore it from my USB drive? Or do I need to kill the pool completely and restore all the datasets to it? Can I trust the latest dataset snapshot that have been replicated since they contain this "corrupted_dir" folder? Will I need to redeploy all my applications (they all use host path)?
Thanks for your help.
