Oh man, corrupted relay logs? That's the worst! I bet the poor DBA is tearing their hair out right now. But hey, at least it's not a full server crash, right? Silver linings and all that.

This is a tricky one, but I think option C is the way to go. Deleting the corrupted logs and reconfiguring the replication settings should do the trick. Just gotta be careful not to mess up the file names, you know?

I agree, option C seems like the safest choice. It's important to make sure the replication settings are correct.

I'm not sure, but I think we should use the relay logs from the master to replace the corrupted ones.

I agree with Mozelle. That seems like the right way to restore replication.

Hmm, deleting the slave's relay logs and adjusting the replication settings sounds like a lot of work. I'd probably just go with the backup option, D. It's the safest bet to ensure a clean restart.

Ah, I see. The slave's relay logs are corrupted, but the master's logs are still intact. Sounds like option B is the way to go. Just need to copy those relay logs over to the slave, and we should be good to go!

Great, let's go ahead and replace those logs and get the replication up and running again.

Exactly. Once we do that, we can restart the replication and everything should be back on track.

That makes sense. We just need to replace the corrupted logs with the ones from the master.

Option B) The relay logs from the master should be used to replace the corrupted relay logs.
