I'm trying to setup a container (CentOS 7) that hosts an SRP target using LIO. As far as I can tell the container has the correct access to the bits on the host (CoreOS 4.7.3) because I'm able to start targetcli without error and have been successful in creating a new block device. The next command I'm trying to issue is /srpt create wwn=<Infiniband WWPN> but I get the error
Could not create SRPTFabricModule in configFS
The command that I've used to run my container is
docker run -it --rm --privileged --cap-add=ALL \
--tmpfs /run --tmpfs /run/lock -v /lib/modules:/lib/modules \
-v /sys/kernel/config:/sys/kernel/config \
-v /dev/infiniband:/dev/infiniband hpc/san /bin/bash
This has been everything that I could find is required to use an InfiniBand interface and ZFS in a container. I did find an comment in an issue on the zfsonlinux repo in Github that said to rmmod target_core_mod and then modprobe and mount configfs, but that's for the case where target_core_mod have been loaded without it, and that's not what I have.
lsmod | grep configfs
configfs 32768 4 rdma_cm,iscsi_target_mod,target_core_mod
mount | grep configfs
configfs on /sys/kernel/config type configfs (rw,relatime)
I'm hoping that this is some permissions or access problem between the container and the host because that would probably be easiest to resolve.
