trident-iscsi-tools

This extension provides basic Linux tools like 'cat', 'ls', and other binaries on the host used by the Trident CSI, which are apparently not jet bundled in to Trident itself.

What's Included

  • lsscsi
  • coreutils: ls, cat, dd
  • procps: free, pgrep
  • blockdev

Use Case

To run trident-operator with iSCSI, you need to enable the extensions:

  • iscsi-tools
  • multipath-tools
  • util-linux (for blkid)
  • trident-iscsi-tools

and additionally the kernel modules:

kernel:
    modules:
      - name: scsi-transport-iscsi
      - name: libiscsi_tcp
      - name: iscsi_tcp
      - name: scsi_transport_fc
      - name: dm_multipath
      - name: dm_round-robin

To configure multipath accordingly you need to apply:

apiVersion: v1alpha1
kind: ExtensionServiceConfig
name: multipathd
configFiles:
    - content: |
        defaults {
            user_friendly_names yes
            find_multipaths no
            path_selector "round-robin 0"
        }
      mountPath: /etc/multipath.conf
