SOLVED Error Received: Please help Guru

[tikas tribe]

Hi FreeNAS Gurus,

I'm new to FreeNAS and I setup one for our family business. Currently, I received an error and one folder is currently not readable (See attached file)?

What can I do to restore it? We have important files there. :(

Under Storage> Volume Manager>, When I clicked Manual Setup, I saw that storage (see attached file).

Can I add it? Are my files in there? Can you recommend this to restore my files?

Thank you in advance!

Michelle

Did this happen right after a reboot or power failure?

I would suggest posting hardware information and the output of 'zpool status' in code tags.

The images show nothing that will help troubleshoot really.

As per my tech, after power failure.

Sorry but how will I do that? Thanks!

For hardware information, please give the details of the server motherboard, CPU, memory, the hard drives used for devastator, and the boot drive/device that has the FreeNAS OS on it. Also, what version of FreeNAS is in use. A good start for this information is on the System, Information page of the FreeNAS GUI, like this:

For the output of "zpool status", open the Shell window from the list on the LHS of the GUI, use the size dropdown at the bottom to maximize the size of the window, type "zpool status" on the command line (no quotes) and hit Enter. You should see information similar to this below:

Click the "code" button on the line above your message to get the code tags to appear .

Copy and paste the information from the shell display in between the tags:

Noted.

See details below.

I hope you guys can help me restore my files.

Thanks,

What about the output of zpool import? And if you have important files there, why are you using single-disk pools without any redundancy?

Hi danb35,

Please see zpool import results. Do I have a chance of recovery? :(

I hope you have better resolution. I'm still not declaring as data loss but I need to report tomorrow. :(

Looking forward to a positive response...

 

[tikas tribe]

Based on the details I posted here, can we say that I can proceed to Manual Setup? That I will see my data there knowing it says that "corrupted data". At least, I have files to see there... :(

Thanks in Advance!

 

[danb35]

Do I have a chance of recovery?

Unlikely.

can we say that I can proceed to Manual Setup?

No, "manual setup" would create a new volume, destroying any data on your existing drive.

What's the result of doing zpool import -Ffn Sales? And I again ask,

if you have important files there, why are you using single-disk pools without any redundancy?

 

[tikas tribe]

if the status is true, am I gonna see my files to its state as of Sat Mar 3? After this command, Can I see my files already?

I'm using single-disk pools because I ran out of money. :( After we recover this, I'll make sure I'll do that recommendation.

 

[danb35]

That's what it looks like. The -n flag on that command told the system to just see if it could import the pool, not to actually import it. To import the pool, do zpool import -Ff Sales. If that succeeds, then do zpool export Sales, and then use the Import Volume button in the GUI to import the pool.

I'm using single-disk pools because I ran out of money.

No matter how limited the budget (which I do understand), storing important data on a pool without redundancy or backups is a bad idea--you really need both. Redundancy will protect against disk failure, but not against things like inadvertently deleting the wrong file.

I hope this command succeeds?

From Import Volume, I can't get further...

Should I use Import Disks?

I understand, moving forward, I'll do that after this incident.

 

[danb35]

I hope this command succeeds?

Yes, that's showing success.

Should I use Import Disks?

No, that would be for importing data from a disk with a different format. It might be that the GUI is confused about whether the pool is already imported. Can you just reboot?

Hi danb35,

I'll schedule a planned downtime after 5 hours and give you update.
Hope everything will be fine. :)

 

[danb35]

In the meantime, do zpool import Sales and see if you can see your data from the CLI. I wouldn't expect it to be visible in your shared drives and such, but you can still confirm the data is there.

 

[tikas tribe]

Hi danb35,

After server reboot, I finally saw our Sales files! I did not proceed with the GUI because it works!

Thank you so much danb35! I hope this incident and procedure we did can help other members in the future.
Thank you forum gurus!!! This is closed.




OT: I have other issue but I'll create another thread for this.

 

[danb35]

Glad this is resolved. The issue with Finance looks like there is some data loss, but it will remain to be seen how much.

 

[wblock]

Please back up your data immediately, then consider hard drive redundancy and backup procedures for the future. Also, putting the error message encountered in the Subject of the thread will help to attract readers experienced with that error.
