Hello,

I'm trying to start container:

# docker run -t -i gitlab/gitlab-ce /bin/bash
Error response from daemon: error creating zfs mount of zroottmp/usr/docker/c1d121894f33d8e0cb4d3e481869ac2ce806f4f6359c1b9fa6fad9afb98520c6-init to /usr/docker/zfs/graph/c1d121894f33-init: Failed to call nmount: File name too long

 # docker version

OS: 11.2-STABLE r340361

I guess it's OS related issue which is cannot mount image with long name. Is there any workaround of it?
Comment 1 iron.udjin 2018-11-13 21:40:09 UTC
Workaround is to make dataset as shot as possible. In my case it is: zfs create -o mountpoint=/usr/docker zroottmp/d

I keep this bug open. Possibly somebody will find better solution which allow to use long dataset names for docker.
