I haven't encountered this situation in my scenarios.
I use a TRAID of two 2TB M2 drives and work on a local network.
Previously, the problem was solved by a complete system reinstall. However, I didn't format the drives because the TOS preinstallation didn't offer formatting, and I don't know how to do it in the GUI.
After installing Docker, Immich, and Nginx, creating the shared folder failed again. I don't know exactly when.
I sent a report to
[email protected]. The email included a link to the report file on drive.google.com (Gmail doesn't allow sending zip files). I can post it here if needed.
