iscsi install failure on nodes

I am attempting to get everything installed on my nodes so that I can connect it, but I am running into some issues.

when I run sudo systemctl enable multipath-tools.service I get

Synchronizing state of multipath-tools.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable multipath-tools
Failed to enable unit: Refusing to operate on linked unit file multipath-tools.service

tho sudo systemctl status multipath-tools shows it as active

and when I check sudo systemctl status open-iscsi I get

● open-iscsi.service - Login to default iSCSI targets

Im on Ubuntu 18.04, and this is /lib/systemd/system/open-iscsi.service

from what I can tell, its implied here that those two directories cant be empty, but I though that all the connection stuff would be handled by this container?

Oh yeah that’s a great howto. I’ll add it to the doc! One note about deleting the pvc, it’s less scary if you suggest the user set the reclaim policy to Retain on the PV beforehand…that will prevent a provisioner from deleting the PV.

I also threw together a quick thing on how to migrate data over if you find it worth adding. I found the other two guides on creating and migrating very useful, but nothing went over migrating any data that I already had. And not much on that anywhere else on the internet for that matter. I had someone else give it a read-through already, but if you have anything else to add or change let me know.
