Lost Folder Content

[nishnish]

Hi

We are using Freenas 11.3 for data sharing in a factory. Our most valuable data are Catia parts and drawings. we have a single dataset that has multiple folders including "Catia Parts". All content of that folder is gone however disk usage has not been decreased. I tried regenerating share, unmounting, and mounting again but nothing worked. any idea?

Roll back to the latest snapshot? If that data is valuable to you, sure you enabled regular automatic snapshots, didn't you?

If not, you need to login via SSH - possibly the data is still there but for some reason does not show through the share. You know how to navigate the command line?

Thanks for your reply. I have scheduled regular backup once in 4 days, however, in the past four days, we had some updates which will take time to do again. I navigate to /mnt/My_pool/dataset/Catia Part. "ls" replies that the folder is empty. are there any other sort of navigation? Do you think it would help if I create another NAS and import these disks as a new pool?

Post the output of zfs list and mount, please.
Is /mnt/My_pool/dataset/Catia the folder that is empty but should not be?

Exactly. I have my other folders available except that one.

There is no my_dataset, neither in the mount nor in the zfs list output.

Something missing? Are you using the Web UI shell? Don't. Use putty.exe, Terminal.app, ... to connect via SSH. Then post the complete output of these two commands inside code tags like so:

Thanks for your support. The outputs are from putty.

In that case I am at a complete loss. You don't have a dataset named "my_dataset" and no dataset named "_dateset_01" - are these really the names you are using?
