Wrong storage driver name logged for some WebDAV uploads

[schweigisito]

Describe the bug

Although using STORAGE_USERS=posix (default when deploying via opencloud-compose repo), the server still logs something like

opencloud-1  | {"level":"error","service":"storage-users","host.name":"da308ec0490e","pkg":"rgrpc","traceid":"c00c6727a7ac7a4e8852f1cf0ee4a70b","error":"error: not found: no lock found","time":"2026-05-19T16:37:24Z","line":"github.com/opencloud-eu/reva/v2@v2.44.0/pkg/storage/pkg/decomposedfs/node/locks.go:299","message":"Decomposedfs: could not read lock"}

from time to time.

Steps to reproduce

In my case it happens sometimes when the browser extension Floccus uploads a set of browser bookmarks to my OpenCloud instance via WebDAV. No idea how to reproduce this exactly.

Expected behavior

The real or actual storage driver name.

Actual behavior

The decomposed storage driver name

Setup

opencloud-compose Docker compose deployment using keycloak, LDAP in auto-provisioning mode and app token for the WebDAV access.
