Closed ganning127 closed 7 months ago

ganning127 commented 11 months ago

To reproduce (on branch main):

  1. Start the nfsrods docker container
  2. Mount
  3. Wait until the docker container's logs stop "scrolling" and you'll be able to see the error message

Need to investigate/reproduce.

korydraughn commented 7 months ago

The exception indicates Jargon could not find /tempZone/trash. Perhaps this was caused by a bad configuration, missing trash collection, or invalid arguments to the mount command.

In any case, the application did its job by reporting an error.

I don't think there's anything actionable here.

That sounds fine. Closing as resolved/invalid.
