Unable to mount Borg repo from UI, does mount with Borg CLI

niemer · Feb 8th 2024

I recently performed a clean install of OMV7 and got everything up and running, but when I try to mount a borg repo I'm met with the following error. I'm not sure why there's an extra / in /srv/mergerfs/Data/Backup/BorgBackup/MSOS//MSOS, but I'm wondering if that has something to do with it. I'm able to mount these repos fine using the borg cli.

Code

That isn't causing a problem. It happens because there is a slash on the end on your sharefolder path. I can look at improving it though.

You are using the exact same command as in the output? Does it work with double slashes?

borg mount /srv/mergerfs/Data/Backup/BorgBackup/MSOS/ /srv/mergerfs/Data/Backup/BorgBackup/MSOS//MSOS is the command I used to manually mount the repo, it does work with the double slashes.

I'll also say that this plugin was working as expected in OMV6.

Can you please try the exact command in the error?

Nothing has changed in most of the borg plugin for OMV 7 including mounting a repo. I have no problem mounting a repo unless it has no archives (which makes sense since there is nothing to mount).

Sorry, I misunderstood, running the below command

Code

export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export LANGUAGE=; export BORG_PASSPHRASE=xxxxxxx; /usr/bin/borg mount -o allow_other '/srv/mergerfs/Data/Backup/BorgBackup/MSOS/' '/srv/mergerfs/Data/Backup/BorgBackup/MSOS//MSOS'

results with passphrase supplied in BORG_PASSPHRASE, by BORG_PASSCOMMAND or via BORG_PASSPHRASE_FD is incorrect., but commands like check, list, and info work without problem.

I guess I need to mention that you will have to change the 'xxxxxxx' to your passphrase. If I can't get a good error message, I don't know what to fix.

niemer · Feb 8th 2024

When I change 'xxxxxxx' to my passphrase it mounts correctly.

If you run echo $? immediately after that command, what does it output?

niemer · Feb 8th 2024

The output is 0

Another piece of information, unmounting from the UI works fine.

ryecoaaron · Feb 8th 2024

Well, the same command the plugin is running works and returns a zero exit code indicating success. I'm not sure what I can change in the plugin. Is it still failing? Do you have another repo to try mounting?

niemer · Feb 8th 2024

It's still failing, I have 10 repos that all behave the same.

Can you try the mount from the web interface with omv-engined in debug mode?

sudo monit stop omv-engined

sudo killall omv-engined

sudo omv-engined -df

# try the mount in the web interface, post any error info

sudo killall omv-engined

# to put back in normal mode

sudo monit start omv-engined

The web interface doesn't work when I perform those steps.

Did you run the first three and check the web interface? The last two are to be done after you are done debugging.

niemer · Feb 9th 2024

Yes, after the third command I tried to use the UI, but it is unresponsive at that point. It goes back to normal after the last command.

ryecoaaron · Feb 9th 2024

I use this all the time when testing plugin changes. Are there any errors in the output?

niemer · Feb 9th 2024

I couldn't even log in after using the first command, I did see this.

ryecoaaron · Feb 9th 2024

What output is on the command line though? It should show something.

niemer · Feb 9th 2024

This is all I see

Code

root@omv:~# sudo monit stop omv-engined
root@omv:~# sudo killall omv-engined
omv-engined: no process found
root@omv:~# sudo omv-engined -df
omv-engined[1696339]: Daemon process started (pid=1696340)
