Description Mohua Li 2011-04-18 07:35:38 UTC

Description of problem:
auto reinstall(dirty install) can't proceed if previous HostVG span multi disk, display as


"There appears to already be an installation  on another device:

  /dev/mapper/3600a0b80005b10ca00008e254c7726b1p1

The installation can't proceed until the device is remove"





we should differential HostVG on multi disk, and HostVG on different disk(other than storage_init),

Please provide serial console log and complete command line used to re-install.

The dracut plugin should handle the cleanup of the HostVG on specified installation devices.  This includes the case where it spans multiple disks.
