# Share/LUN UI Fix Script
|
||||
|
||||
This script finds shares that were accidentally broken in the UI and fixes it.
|
||||
Additionally, performs migration of created folders in the roots of volumes to btrfs subvolume.
|
||||
|
||||
|
||||
### Prerequisites
|
||||
|
||||
* You need to be on ReadyNAS OS 6.9.4 or newer. This script contains configuration file data for 6.9.4 that may or may not work with older versions.
|
||||
* You should use this script with ReadyNAS OS 6.10.0 or newer. This script contains configuration file data for 6.10.0 that may or may not work with older versions of ReadyNASOS.
|
||||
* 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.

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.
