Request for a -longhorn variant about elemental HOT 4 OPEN

open-iscsi is in the baremetal variant for SL Micro 6.0 (but might be missing from 5.5 🤔 )

from elemental.

Just to note that although not explicitly mentioned, the iscsi_tcp kernel module is also a requirement. Without it volumes will fail to attach to nodes and longhorn instance-manager logs will show: libkmod: kmod_module_insert_module: could not find module by name='iscsi_tcp'\niscsiadm: Could not insert module tcp. Kmod error -2\niscsiadm: iSCSI driver tcp is not loaded. Load the module then retry the command.\niscsiadm: Could not perform SendTargets discovery: iSCSI driver not found. Please make sure it is loaded, and retry the operation\n: exit status 12"

Another gottcha - If you want to use a Longhorn volume with the access mode of ReadWriteMany (RWX) then nfs-utils or nfs-common is also required, else you'll run into errors along the lines of: [MountVolume.MountDevice failed for volume pvc-foo : rpc error: code = Internal desc = mount failed: exit status 32 Mounting command: /usr/local/sbin/nsmounter Mounting arguments: mount -t nfs -o :/pvc /var/lib/kubelet/plugins/kubernetes.io/csi/driver.longhorn.io/globalmount Output: mount: /var/lib/kubelet/plugins/kubernetes.io/csi/driver.longhorn.io/ globalmount bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program.]

We should probably define a -longhorn variant 🤔
