Move only one domain in vmail to another storage device

[alexyz41]

Hello,

I followed the steps ("new way") on https://mailcow.github.io/mailcow-dockerized-docs/u_e-dovecot-vmail-volume/ but instead of moving the entire folder, I just moved one folder corresponding to one domain.

1. I renamed the folder from /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/domain.com to domain.com-old
2. I created a symblink to /mnt/new-volume/domain.com
3. Changed owner of link to user with id 5000
4. Copied all contents of domain.com-old to /mnt/new-volume/domain.com

I started again with docker-compose up -d and tried to create a new mailbox in that domain, and it success, but when I try to log in to that mailbox, it says that an internal error happened. Here are the logs:

Refer to server log for more information. [2021-08-07 20:21:03] (0.001 + 0.000 + 0.001 secs)."; result = 0; }

Is it a permission error? I don't really see where is the error since I set all folders to be owned by user with ID 5000.

Any help would be appreciated.

Thanks

Hi,

Please post support questions here: https://community.mailcow.email/

Symbolic links will not work. Try a bind mount like mount -o bind /some/where /else/where
