[edit] Anaconda iSCSI Cleanup
[edit] Summary
Improve anaconda's iSCSI support.
This is a complete iscsi rewrite that also adds the new libiscsi and associated python bindings.
[edit] Owner
- Hans DeGoede <hdegoede@redhat.com>
[edit] Current status
- Targeted release: [Fedora 11]
- Last updated: (04/17/09)
- Percentage of completion: 100%
- We did not submit this as an official F11 feature since FESCO thought that it was more in the nature of cleanup, but the work is complete in F11
[edit] 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
Limitations:
- For non ibft discovered devices, the sendtargets discovery authentication information (username and secret) must be identical to the authentication information for the portal to the target.
[edit] Benefit to Fedora
Fewer anaconda bugs and easier maintenance. Additional support for ibft, CHAP, reverse CHAP.
[edit] Scope
- Review and fix numerous reported problems
- Include latest ibft, CHAP and reverse CHAP support
[edit] 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
[edit] 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.
[edit] User Experience
[edit] Dependencies
None
[edit] Contingency Plan
None; this is a necessary revision of existing (broken) support
[edit] Documentation
See http://people.atrpms.net/~hdegoede/html/index.html for details of the libiscsi API
