Identical issue.
On the host, the XXXXX volume is an overlay (I don’t want to take the risk of loosing my data on the underlying filesystem and I don’t want to get GB of data duplicated either):
{
"CreatedAt": "2020-11-03T04:23:18Z",
"Driver": "local",
"Labels": null,
"Mountpoint": "/var/lib/docker/volumes/XXXX/_data",
"Name": "XXXX",
"Options": {
"device": "overlay",
"o": "lowerdir=/mnt/extra/gphotos,upperdir=/mnt/extra/pydio-upper,workdir=/mnt/extra/.work.pydio-upper",
"type": "overlay"
},
"Scope": "local"
}
]
In that /mnt/extra/gphotos directories I’ve various files and directories.
I run cells, with this command:
docker run -ti --network pydionet -e CELLS_NO_TLS=1 -e CELLS_EXTERNAL=https://foo -e CELLS_BIND=127.0.0.1:8080 -p 8080:8080 -p 33060:33060 -v cells-workdir:/var/cells -v XXXXX:/var/cells/data/XXXX -v cells-logdir:/var/cells/logs -v /etc/localtime:/etc/localtime:ro pydio/cells
and I’m experiencing the same problem.

Sadly it even breaks all other datasources: In the backend they all happen to be “unvailable”.
I think it’s related to Sync DataSource (similar use case)
