Docker on ubuntu server and CIFS mount windows share broken

I mount a windows 10 or windows server 2016 share (smb,cifs) into ubuntu and map that folder into docker container. At first it looks ok, the files can be read, created and deleted. But when it comes to expanding the files, it fails. The problem pops up when mapping mssql-server-linux data folder on the shared drive. The same problem occurs with sqlite.

If i share the folder from an old synology disk station also using smb (but version 1) it works as expected.

Tested Docker versions 17.09, 17.12, 18.02
on Ubuntu Server 16.04 with kernels 4.4, 4.8, 4.15).

Does this work for anyone ?

This is a sample setup that duplicates error with mssql-server-linux image.

A. Windows Part

  1. create windows user testone pass testone
  2. share a folder as “share” (file system doesn’t matter ntfs,exfat,fat32)
  3. give full permission to testone (on share and ntfs if applicable)

B. Linux Part

  1. mount directory
    mkdir ~/hostshare
    sudo mount -t cifs ///share ~/hostshare -o username=testone,password=testone,file_mode=0777,dir_mode=0777,vers=3.0
  2. run microsoft/mssql-server-linux
    docker run
    -p 1433:1433
    -v ~/hostshare:/var/opt/mssql/data
    -e “ACCEPT_EULA=Y”
    -e “MSSQL_SA_PASSWORD=TestOne01”

run fails when updating mastlog.ldf (expand file)

The same thing with Sqlite, Database and journal files created, but when creating db objects
it can’t expand database file and fails. There is some dotnet code needed for that example
which i can provide if anyone is interested.

So it’s not microsoft mssql server exlusive error.

PS: tried also with volumes, but the result is unchanged.

Just found one solution:
downgrade windows server side to SMB 1.
This can be done by installing windows feature
SMB 1.0/CIFS File Sharing Support -> SMB 1.0/CIFS Server
install and reboot
change mount to vers=1.0

this exposes some serious security issues so i hope that someone figures out how to use SMB 2 or 3.
