opencloud fails to start: repeated "no such device" errors

[chris-pollux]

I am trying to run Opencloud with Collabora using Caddy as proxy.

Unfortunately the start of Opencloud fails with repeated errors:
2026-01-23T20:28:50Z FTL service terminated error=19 event="opencloud: Failed service 'service.SutureService{exec:(func(context.Context) error)(0x5588e4ba36e0)}' (5.997764 failures of 5.000000), restarting: false, error: no such device" failures=5.997764185867026 line=github.com/opencloud-eu/opencloud/opencloud/pkg/runtime/service/service.go:400 restarting=false service="service.SutureService{exec:(func(context.Context) error)(0x5588e4ba36e0)}" supervisor=opencloud threshold=5

I set permissions for config and data and tried removing files to start on a blank slate.
Any hints?

Okay, I found the reason. My data directory is on a mergerfs drive: opencloud-eu/opencloud#1785
For now I can run on another drive that works.
