Lost access to RPI's disks via a home network

Hello All,

Need your help. I use OMV from v5 and thought that I had some experience. But I didn't find how can I solve this problem.

A couple of days before, I suddenly lost access to my RPI's disks via the home network on W10 and Linux machines. I did nothing in the OMV setting for much time.

My home machines are:

RPI4 with OMV 7.4.17-2 (Sandworm); Linux 6.1.21-v8+ (two external USB disks WD 8TB each)

W10 laptop

Desktop Linux Mint 22.1

DuneHD

What I tried to do:

I reset credentials on the W10 machine and tried to log in to my network disks once again - unsuccessfully. A folder is empty - I don't see network disks. I tried to switch on/off SMB service on OMV (web) - no results. I went to SMB shares on OMV and found out that there is empty. When I try to add a new share and specify one of my disks for it - I receive an error - something like - the same share already exists.

What is the current stage:

I lost access to my network disks from W10 and Linux machines (except SSH access on Linux). I still have access to OMV via the web and my DuneHD.

Also, now, I can't update OMV (via web) - I have a "pending message" - when I try to apply the changes - I get an internal error 500.

I hope for community help. Please advise how can I fix this problem.

Just additional info to my case.

I receive these Samba's errors while trying to update OMV and using a reconfiguration network via 'omv-firstaid'.

See attachment.

Also when I go OMV > Services > SMB/CIFS > Shares I receive the error below:

The ways below didn't help:

I still have access to RPI via SSH and from my mediabox (NFS). Also syncthing works (in the background) fine on W10 and Linux machines. I don't see network folders via W10 and on Linux machines.

Hi votdev,

Thanks a lot for your recommendation.

Could you ask to provide with me some instructions on how to do that correctly? I know that the order of actions in this case is important.

Can I do it via shell or a web interface of OMV? How it can touch my data on the shares?

Why do I still not have an availability to make an update on OMV (not via shell, not via web)? How does it relate to my problem with SMB?

I worry about saving my data on both of my external disks. Both of them are old (3-4 years). And I think this problem can be related to bad blocks on them, as a possible option. Also, I would like to avoid clearing and rebuilding whole my data files on my disks because this process can take at least 2-3 days due to huge disk sizes (8Tb+8Tb).

I would appreciate your comments here.

Hello crashtest,

Thanks a lot for your recommendations and comments!

Maybe my question is stupid but I couldn't find the object with the uuid 65820033-22fd-4320-9ca6-f6dd02fc8c3f on the web interface of the OMV. There are my external disks shown in the menu Storage/Shared Disks:

As I mentioned my menu Services/SMB/CIFS/Shares is empty. Of course, I can try to create new shares there but I worry that can add a mess.

So, I found nothing that mentions 65820033-22fd-4320-9ca6-f6dd02fc8c3f in the OMV web interface. As I understood it was mentioned in log files only.

This is my data for disks from the menu Storage/Disks:

Similar data from the menu Storage/File Systems:

Please advise on how can I find this uuid?

Regarding saving my data - thanks for the links - I will meet with it. You are right, the time to make a deep HDDs check has come. I was doing details OMV configuration a long time ago (3-4 years ago). All of this time it worked nicely. Set up and forget. I thought it worked in such a way.. ( And I didn't interfere. Honestly speaking, I am too lazy to make a re-configuration (replace my disks) from the beginning because firstly I need to buy a new HDD (at least 1 disk for 10TB, it is expensive), replace correctly my old disks, and spend 2-3 days setting up OMV (wipe a new HDD, moving data, creating new shares, etc.) and then additionally spend a couple of weeks to checking of the setting up of my applications which running on OMV. I am using these apps right now for my work. Stopping them will cost me additional biz losses.

I use 'syncthing' to synchronize data with another Linux machine in my network. So, my data is stored on two other PCs but in parts. By the way, it is still working w/o a problem in the background on RPI, W10, and Linux machines. So, the data can be saved, but, sh1t, the process of a re-configuration will take a lot of time.

I will try to avoid this moment as long as possible.

Hello Soma, crashtest, votdev,

I found the section with 65820033-22fd-4320-9ca6-f6dd02fc8c3f in /etc/openmediavault/config.xml and removed it.

After OMV rebooted, I saw my shares in menu Services/SMB/CIFS/Shares. They are such as were before. No changes.

Then I managed to do the OMV update successfully. And finally, I saw my shares on other PCs. Everything works okay.

Please put this thread in solved. We can close this case.

I want to say genuinely thank you very much! May god bless you!

I have switched on a small regular donation for your team to the paypal@openmediavault.org account.

I regret only that I have not done it before.
