Help please with degraded pool.

[myzona]

Hello, it's what I got from zpool status -v

Code:

 pool: Titan
state: DEGRADED
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

errors: Permanent errors have been detected in the following files:

        /var/db/system/cores/python3.6.core

I don't have backup to restore this file. What is my other options?
Thank you.

Assuming that zpool status command is accurate, you have a single device pool with no redundancy whatsoever.

You have no other options.

The reason it's a single device pool because it's my media storage, shared on my network. With time I am installed a Plex server in a jail. All I need,if it's possible, to move my media and plex jail to a new pool with out to reconfigure again samba share and Plex media server. Thanks for any help.

The most straightforward way to do this would be to add a second disk to your pool as a mirror of the first, let it resilver, then remove the first disk. Unfortunately, all of that would need to be done at the CLI--despite an open feature request for at least the last five years, and the fact that it would be trivially easy to implement, the GUI still doesn't support doing this.

The better thing to do, after the mirror is added, would be to replace the first disk--this will give you redundancy, significantly reducing the chances of having this problem again.

This type of error generally indicates a failing drive. Have you been getting error messages in the GUI or by email?

In shell after zpool status -v

As danb35 recommends I will add a second disk and resilver.
