/etc/iscsi/initiatorname.iscsi not found

[xing-yang]

After installing with opensds-installer ansible in csi mode with LVM backend, the nodeplugin pod failed to start. The reason was /etc/iscsi/initiatorname.iscsi not found. "sudo apt-get install open-iscsi" should be part of the deployment step if LVM is selected.

Got it, because open-iscsi is installed in some environments by default, so we forgot to add it in the package.

[leonwanghui]

But I am wondering if we can just add open-iscsi package in the Dockerfile of csi-plugin, or install it on the work node which hosts the csi-plugin service?

I found that open-iscsi is already installed when installing nbp modules using ansible, so I guess we should add this package installation in csi Dockfile.
