Disk usage on /dev/sda1 from the Hetzner Cloud, as it's reaching 75% capacity

AlexCroydon

Hello everyone, I am currently using mailcow-dockerized for my client’s email system. I’ve encountered an issue with my Disk usage on /dev/sda1 from the Hetzner Cloud, as it’s reaching 75% capacity with only 29G out of 41G remaining. To address this, I have created a new volume called “volume-mailcow-1.” However, I’m a bit apprehensive about attaching this new volume, as the client’s emails contain crucial attachments. Could you please direct me to a step-by-step guide that explains how to safely attach a new volume?

Thank you in advance.

First thing would be to backup your mailcow if you’re not already doing that

https://docs.mailcow.email/backup_restore/b_n_r-backup/

After that have a look at https://docs.mailcow.email/manual-guides/Dovecot/u_e-dovecot-vmail-volume/

DocFraggle Hi, Is the “new way” safe, someone is using this mode on production with newer docker versions ?

As described in the docs above, inside your mailcow directory of course, run

MAILCOW_BACKUP_LOCATION=/path/to/your/backup/dir ./helper-scripts/backup_and_restore.sh backup all

And maybe copy it to a safe location afterwards, i.e. your NAS storage, feel free.
Just wondering, you’re running mailcow for your client and don’t have a backup in place yet?

Yes it is safe. I am using it since some months. Never had an issue.

I don’t know, I guess it’s safe. You also could just rescale your Hetzner VM to increase your disk, so you don’t have to fiddle around with the attached volume
