Hi,
I have an issue when running docker with overlay over a glusterfs mount :
error creating overlay mount [...] invalid argument.
My server is a Centos 7 with 4.10.8-1.el7.elrepo.x86_64 kernel.
It has a glusterfs mount point (the volume has been formated in xfs):
0001.storage.development.internal:/docker /data/docker/ glusterfs defaults,_netdev 0 0
The output of docker info :

When I launch any container, like hello-world, I got this error :
/usr/bin/docker-current: Error response from daemon: error creating overlay mount to /data/docker/overlay2/0d6bf43187f55492b9f73225f7b5998c0069290f0de26d42158676119d84a8c2-init/merged: mountfrom re-exec error: exit status 1: output: invalid argument.
See ‘/usr/bin/docker-current run --help’.
And the output of dmesg :
[69155.014371] overlayfs: filesystem on ‘0d6bf43187f55492b9f73225f7b5998c0069290f0de26d42158676119d84a8c2-init/diff’ not supported as upperdir
I don’t understand why I got this error.
Is there an issue between glusterfs ↔ overlay ?
Or is it my setup which is wrong ?
If anyone can help me,
thanks.
