# Share/LUN UI Fix Script

This script finds shares that were accidentally broken in the UI and fixes it.


### Prerequisites

* You need to be on ReadyNAS OS 6.9.4 or newer. This script containts configuration file data for 6.9.4 that may or may not work with older versions.
* Either the ReadyNAS needs internet access or you need to copy/paste the data into a file on the NAS via SSH.
** For internet access, ensure you can reach the internet and DNS is working properly.
* This does not work in `Tech Support mode`. You must be in `Normal mode` and `readynasd` needs to be running. 

### Running

#### Network-enabled ReadyNAS (Automatic)
To quickly resolve the shares and LUNs not showing in the UI, you can copy/paste the following command into a terminal and the script will automatically run. 

```
root@readynasos:#/ curl -s https://gitlab.codycook.us/readynas-scripts/share_lun_ui_fix.sh/raw/master/share_lun_ui_fix.sh | bash
```

Refresh the UI and the shares should be restored.

#### Internet-disabled ReadyNAS (Manual)
* Download the contents of [https://gitlab.codycook.us/readynas-scripts/share_lun_ui_fix.sh/raw/master/share_lun_ui_fix.sh](https://gitlab.codycook.us/readynas-scripts/share_lun_ui_fix.sh/raw/master/share_lun_ui_fix.sh)
* Copy the data into your clipboard.
* In the ReadyNAS terminal, type: `vi /root/share_lun_ui_fix.sh`
* Push `i` to enter insert mode, then right click into the console. This will paste your clipboard (in most cases). Only click once.
* Push `esc` and then type `:wq` then hit enter.
* Type `chmod +x /root/share_lun_ui_fix.sh` then type `/root/share_lun_ui_fix.sh`
* The script will run. 

### Acquiring debug information

===============================
Share and iSCSI Rebuild v6.9.4
===============================
NOTE: This version of readynasd creates share backups in /var/backups/shares.
      When possible, you should try and restore a valid backup config from this directory.
      This share config gets rebuilt every time readynasd restarts. Because of this, we'll make a backup of the existing share backups before proceeding.
Generating backup config...... done! Backup complete!

=============================================
See the last modified dates and determine if you can restore from that config or not instead of using this script.
It is best to pick a date before the shares disappeared from readynasd.
