Matt has written a library to process these disks: https://github.com/mdbooth/libldm and at some point in the future we can include it in libguestfs. Matt, do we need libldm to be incorporated into libguestfs for RHEL 7 GA? Yes. Fixed upstream with comprehensive new set of APIs. The fix will appear in libguestfs 1.20. |
Created attachment 555562 [details] Windows 7 disk management program showing disk layout Description of problem: I created a Win7 guest that has 3 block devices. The first (system disk) is converted to a dynamic disk, and libguestfs can kind of work out what's on it. The second two disks are arranged as a spanned volume (like a VG across 2 PVs), and the kernel doesn't understand it at all. [See attached PNG file] virt-filesystems -d Win7x32Dynamic --all --long -h Name Type VFS Label MBR Size Parent /dev/sda1 filesystem unknown - - 992K - /dev/sda2 filesystem ntfs System Reserved - 100M - /dev/sda3 filesystem ntfs - - 16G - /dev/sdb1 filesystem vfat - - 2.0G - /dev/sdc1 filesystem unknown - - 2.0G - /dev/sda1 partition - - 42 992K /dev/sda /dev/sda2 partition - - 42 100M /dev/sda /dev/sda3 partition - - 42 16G /dev/sda /dev/sdb1 partition - - 42 2.0G /dev/sdb /dev/sdc1 partition - - 42 2.0G /dev/sdc /dev/sda device - - - 16G - /dev/sdb device - - - 2.0G - /dev/sdc device - - - 2.0G - Version-Release number of selected component (if applicable): 1.15.16 How reproducible: 100% Steps to Reproduce: 1. Create Win7 guest with 3 block devices. 2. In Disk Management, convert all disks to Dynamic disks. 3. Create a spanned volume across the second and third disks. Actual results: System volume can be read, but spanned volume cannot be seen at all. Expected results: Should be able to recognize it as a spanned volume. Additional info:
