Plugin doesn't want to work

[msva]

Hi there!
Can you advice me, what can I doing wrong?

Check dmesg, if you see lines like libceph: parse_ips bad ip [hostname]

...your version of libceph doesn't support connecting to hostnames in the servers config, change to IPs.

for me the error is similar as msva tho the issue comes from the mount_opts.

Without the option eveything works fine, i can create and mount volumes, tho as soon as i add the mount_opts it fails with the error below :
docker: Error response from daemon: error while mounting volume '/var/lib/docker/plugins/57a73cc84c4b97e0c56217a908f244d948f90828836f851a37bc88145a3830cc/rootfs': VolumeDriver.Mount: could not mount the vol: error mounting source 192.168.45.128:/ to target /var/lib/docker-volumes/a96f376fb3efcf80748289cf6fa96f4f0359066ffb3c3d7eebb30ebea0b21ae0: invalid argument.
