Manual run Rsync works but UI throws an error and email notification spams my inbox every 2 mins

NunoAlex · Feb 22nd 2021

Hello OMV experts,

I'm using Rsync client + RSync Server (2 x Raspberry 4B) to backup data from one NAS to a backup NAS and everything was working fine for a month or two.

I recently had to rebuild the Raid storage on the backup NAS and I had to delete/recreate all the Rsync jobs (nothing changed on the Rsync server).

However, now when I manually start a RSync Job, I get this error:

Code

The rsync job seems to work fine but I can't see the job output on the UI due to the error above and I'm getting spammed every 2 minutes with an email like this:

Code

Subject: [HOSTNAME] Cron


Please wait, syncing <USERNAME@192.168.x.x::MODULENAME> to </srv/dev-disk-by-uuid-1234567-..-1234560abcd/backups/MODULENAME/> ...

If I disable the option to "Send command output via email" on the Rsync Job everything works and I can see the Rsync progress on the system logs, but I'm wondering what happened since this was working fine before, i.e. I was able to start an Rsync job, see the output on the UI and receive 1 single email when finished with all the output together.

I've already tried to re-create the jobs again without success. I'm using the latest build and I have already installed all the available updates and rebooted the device.

Any thoughts?

[update] I think the emails every 2 minutes are because the job is running continuously as didn't provide any schedule (* * * * *). Now it's set to once per week and the email spamming should stop.

Though, the error above is still an issue.

Could you please add -v -v to the extra options and then re-run the job? Please also run journalctl -f in parallel to check if there are more useful information why the job fails. I assume the shell is missing something when running the rsync job to a remote system.

Sorry it's been a while, but you know what? It's working ok now.

I didn't make any changes on my rsync schedule jobs so I guess the latest updates fixed the issue.

Many thanks votdev for checking!

Here's my system information in case it helps:
