Anaconda iSCSI Cleanup

Summary

Improve anaconda's iSCSI support.

This is a complete iscsi rewrite that also adds the new libiscsi and associated python bindings.

Owner

  • Hans DeGoede <hdegoede@redhat.com>

Current status

  • Targeted release: [Fedora 11]
  • Last updated: (02/10/09)
  • Percentage of completion: 95%

Detailed Description

iSCSI support in anaconda needed extensive cleanup. This feature replaces existing code with new code using libiscsi.

Fixes:

  • Report error when we cannot add a disk instead of silently failing (461830)
  • Report error when trying to use iscsi from kickstart without having an iscsiname directive first (463156)
  • Better feedback while scanning iscsi disks
  • Make ibft work with chap and 2-way chap
  • Make ibft configured disks available for upgrades and in rescue mode
  • Make ibft boot work even when iscsi-initiator-utils is installed after the kernel in the transaction

Benefit to Fedora

Fewer anaconda bugs and easier maintenance. Additional support for ibft, CHAP, reverse CHAP.

Scope

  • Review and fix numerous reported problems
  • Include latest ibft, CHAP and reverse CHAP support

Test Plan

  • Test install to a regular disk with /home on iscsi using no authentication
  • Test install to a regular disk with /home on iscsi using 1-way CHAP
  • Test install to a regular disk with /home on iscsi using 2-way CHAP
  • Test install with / on iscsi using an iBFT capable system using no authentication
  • Test install with / on iscsi using an iBFT capable system using 1-way CHAP
  • Test install with / on iscsi using an iBFT capable system using 2-way CHAP
  • Test install with / on 1 iscsi target and /home on a different target using an iBFT capable system
  • Test install with / on 1 iscsi lun and /home on a different lun of the same target using an iBFT capable system

Known Issues

  • When using NetworkManager for network configuration and using an iscsi /, other iscsi based file systems (ie /boot) will not be
 brought up automatically.

User Experience

None

Contingency Plan
