"Unable to locate /data/portainer.db on disk"

[bitshiftnetau]

I have portainer running as a service in Arch linux. The portainer.db file is located at /var/lib/portainer however when I pass that in to docker it cannot locate.

This is the exact command I enter

docker run --rm -v portainer_portainer_data:/var/lib/portainer portainer/helper-reset-password
I have also tried making a /data folder and placing the portainer.db file there

[bitshiftnetau]

tried building manually and passing /var/lib/portainer into binary, no luck

Eu também tive o mesmo problema... Estou procurando algo na internet, mas até agora não consegui resolver....

It's because the portainer data doesn't actually exist in the volume for some reason

[z3cka]

@bitshiftnetau check to see if your portainer data volume has a different name. You can see what your volumes are with: docker volume ls

In my case, my volume was called portainer_portainer-data —because that's the name I used when creating the volume originally.

Just want to share the fix on my Synology NAS. The folder path needs to be specified to make it work.

sudo docker run --rm -v /volumeX/docker/portainer:/data portainer/helper-reset-password

This solved my problem, thank you.

Had he same problem on a synology the command above fixed it.

docker volume ls does show the volume as portainer_data but I had to specify the full path as above.

sudo docker run --rm -v /volumeX/docker/portainer:/data portainer/helper-reset-password

Thank you. This solved my issue as well.

Pretty sure I ran the "/volume1/docker/portainer-ce:/data portainer/helper-reset-password" to get me over the hump.

Much appreciated

2023/02/27 18:56:53 Data store not found at /data`

mentioned directory to mount is available and listing shows me that there are portainer.db / .key and .pub

Any help is highly appreciated.

Thank you

Running docker/portainer on a Western Digitial PR4100.

docker run --rm -v portainer_data:/data portainer/helper-reset-password

2023/07/22 18:32:09 Unable to locate /data/portainer.db on disk

I've located the portainer.db file on a mnt but can't get passed this error. I don't think the -v is correct. I'm thinking that this needs to actually mount the folder first to get docker to think it's a volume.

Help is appreciated.

Hi @scuba-fan,

I had the same issue and what I did was search for the file:

find . -name portainer.db

It was found in:
./opt/portainer/portainer.db

Then I executed the docker run command as follows:

docker run --rm -v /opt/portainer:/data portainer/helper-reset-password

This time if was successful for me:
{"level":"info","filename":"portainer.db","time":"2023-08-14T13:05:30Z","message":"loading PortainerDB"}
2023/08/14 13:05:31 Password successfully updated for user: ...

Hope that helps!

Worked for me. Did sudo find / -name pertained.db which gives you path. Then just replace the portainer_data with the path

[CptCurk]

I found everything that I reported on the thread in the official forum of WDcommunity.

But I'm stuck a step ahead of yours : #4

If there is someone who could save my day ? ^^'

2024/01/11 16:15:56 Unable to open the database, err: timeout

I got that when I try to do the command : docker run --rm -v /mydockerfolder:/data portainer/helper-reset-password

Any idea ? I indeed tried docker stop portainer command it gave me : 'portainer'

Then I try 'docker start portainer' and it gives me : Error response from daemon: driver failed programming external connectivity on endpoint portainer (222524611a7e68f9826958beb6e56935f3daeea3b8c3dba19e810c2ada96865f): Error starting userland proxy: listen tcp4 0.0.0.0:8000: bind: address already in use Error: failed to start containers: portainer

Any idea ?
I don't know if it somehow the same issue. To me it looks the same ! ^^'

[adamphetamine]

in case anyone doesn't quite get this- the written example says

docker run --rm -v portainer_data:/data portainer/helper-reset-password

My Portainer docker setup on Synology used this path instead of 'portainer_data' -

volume1/docker/portainer/data

So my complete command was-

docker run --rm -v /volume1/docker/portainer/data:/data portainer/helper-reset-password

Stop the running portioner container before you execute the command.
