Expansion chassis not detecting in ReadyNAS 4312S

Question

Hello,&nbsp;We have a ReadyNAS 4312S with EDA 4000 Expansion chassis. It has 36 slots populated (12 slots in 4312S&nbsp;+ 24 disks in Expansion Chassis).&nbsp;&nbsp;30 * 8TB Disks in RAID6 - /data volume5 * 14TB Disks in RAID5 - /data1 volume1 * 7.68TB SSD in RAID0 - /ssd_data volume&nbsp;Few days back we rebooted the NAS and the volumes didn't come back online automatically. After another reboot, /data1 and /ssd_data came online but /data was showing down. After a lot of digging around, I finally was able to mount it manually and it worked.&nbsp;But in the GUI, the shares related to /data volume isn't showing up (screenshot attached for Reference). Any thoughts on how to fix this? (any particular service that can be restarted to fix this issue?)&nbsp;And to expand the volume, we added an expansion chassis using the second SAS port. We populated 7 disks in the expansion chassis. The disks are detected in the logs but the expansion chassis is not showing up in the GUI.&nbsp;&nbsp;Due to this. we cannot provision the volume? I did look around but didn't know how to fix it. Any pointers on how it can be fixed?&nbsp;Attached a few screenshots. Please let me know if you need more info. Thanks.

There is a script that can be run via SSH that's for this type of issue, but I've not looked at it to see if it'll work right with the EDA attached.&nbsp; So, it is best to wait for one of the Netgear mods to respond and verify it will.

Thanks for the response. If you have any inputs on where I can access that script, it will be helpful. Thanks.

The script that repairs the share configuration is here:&nbsp;https://gitlab.codycook.us/readynas-scripts/share_lun_ui_fix.sh
&nbsp;
But I agree with&nbsp;Sandshark&nbsp;that it would be best to get some guidance from Marc_V&nbsp;or JohnCM_S&nbsp;before you run it.&nbsp; Another option is to contact Netgear paid support via my.netgear.com.

I just looked at the script and ran the part of it that finds all volumes and shares, and it works on my RD5200 running OS6 with a non-Netgear external; SAS 24 disk array (which doesn't show up in the GUI like your EDA4000 does) and it did find all the shares and volumes, so I think it should work with your set-up just fine, assuming what it fixes is the actual cause of your problem.&nbsp;One thing you can do first is to check that whether the entries this fixes are actually missing.&nbsp; For volume data, use&nbsp;ls /data/._share -all.&nbsp; If there isn't a listing there for each share on the volume, then that is your problem and the script should fix it.

Thanks for sharing the script StephenB&nbsp;and thanks for the inputs&nbsp;Sandshark&nbsp;&nbsp;Couple of points:In the NAS, 'ls /data/._share --all' shows up the volumes in CLI and everything is working as expected, its just that volumes don't show up in the GUI. Will running this script fix that issue? (and not break anything else?)The NAS is on ReadyOS 6.9.3 but I believe the script expects v6.10.0 or higher. Is it stll safe to run the script?Thanks once again for your help.
