Understanding scrub result - Mar 22 release

Could someone from subspace team explain to me if there is anything wrong with my scrub result below?

Especially I see the log line below, but I don’t think the file is corrupted since I can still open it

2024-03-24T08:32:34.121348Z ERROR {farm_index=1}: subspace_farmer::commands::scrub: Irrecoverable farm error occurred, your file system might need to be repaired or disk might need to be replaced path=false error=Farm info file does not exist at false\single_disk_farm.json

Full log below. Can I suggest the we set --dry-run to false by default. If people don’t notice, they’ll have to run srub 2 times which will take a lot of time and effort.

The message was incorrect, but it was false by default: Fix incorrect `--dry-run` message by nazar-pc · Pull Request #2637 · subspace/subspace · GitHub

It is the second command that had --dry-run enabled in your case (false was interpreted as a second farm, which is why you’ve got irrecoverable error for it).

Either way, looks like your farm was in a good shape and there was nothing to fix.

Got it. Yes, I didn’t read the result of 2nd run carefully.
