Description of problem: While reinstalling a system using kickstart its not possible to preserve a single Logical Volume. Currently the complete VG needs to be preservered. How reproducible: Always Steps to Reproduce: Install a system with multiple LV's in a single VG. Now re-install the system using kickstart and try preserving a single LV. Actual results: No actual option to to this. Expected results: Option must be provided to accomplish this task. Additional info: However a potential workaround would be to do the VG split from a %pre script to isolate the LV from the existing VG and then just name the LV with --preserve in the partitioning section.
The logvol command allows specifying --useexisting, which should format an existing logical volume and reuse it. Is this not working? Please attach your kickstart file and /tmp/anaconda.log file to this bug report.
