Failed to find metadata for existing index .kibana_task_manager [location: Yi_UxiceTwS093xLAQJpzw, generation: 30]

Hi all,
Due to a disk space problem, I've deleted the indexes and now I'm getting the following error:

java.io.IOException: failed to find metadata for existing index .kibana_task_manager [location: Yi_UxiceTwS093xLAQJpzw, generation: 30]

Have you seen this before? Is it possible to recreate it or somehow start the elastic again?

Can you share the whole error message, including the stack trace?

Also, when you say you deleted the indices, what do you mean? Did you use the delete index API?

Hi David,

Regarding the deleting process, I've just went to /data/nodes/0/ and deleted everything.

Following the whole error message, I've only masked the machine name.

Are you sure you deleted everything under /data/nodes/0/? I think you might have left something in /data/nodes/0/_state. You'd be best off deleting the whole 0 folder.

You were absolutely right. After deleting the folder it worked.

Thank you.
