```auto Level : info Logger : pydio.grpc.data.objects.local2 Msg : ERROR Invalid command line arguments: Cross-device mounts detected on path (/media) at following locations [/media/media02]. Export path should not have any sub-mounts, refusing to start. Ts : 1675391040 SpanUuid : span-5 ``` This is a binary install. I am choosing the import data option. I have had the same problem trying to implement the flat option. There is a folder on the NAS already hence the import data option. The mount instruction is: 192.168.0.19:/volume1/Media02 on /media/media02 In case it matters this a synolgy nas ds220. I am also running smb on it so I can see the disk from my windows work station. in addition I have tried mapping to just /mnt or /media - but I can see the interface requires a 2nd level. Also I tried a three level map such as /volume1/Media02 on /media/media02/top - this failed with the same error. the media folder is owned by the user running cells - permission rwx for everybody the media02 folder is owned by the user running cells - permission rwx for everybody Just as a point of comparison I mounted a usb drive at /media/usb-drive and I get the same error when creating a storage entry. What should I be looking at next. Thanks ---

I tried that and was able to get the service to run but it failed to sync the data with the above error. I am really stuck here without the ability to connect to some large data store I will have to use a less desirable server application like own or next (cloud). Any help will be appreciated. ---

I run unraid. Used the linuxserver image, but mounted /config/data to a custom share. That seemed to work fine so I wanted to add a workspace for my media as well. I added a volume that points to the media share and tried adding a data source. Result is the same as what you have. It’s frustrating since I really like the software, but it is a very important feature for me. ---
