...'t work as expected (unable to find requested GPT disk/partition). The entered guid is correct according to gdisk and chain.c32 debug information but still chain.c32 claims it can't find the drive. The bug is located in function find_by_guid, line 991. It is is_me = !memcmp(&header->disk_guid, &gpt_guid, sizeof(*gpt_guid)); but should be is_me = !memcmp(&header->disk_guid, gpt_guid, sizeof(*gpt_guid)); as memcmp takes two void pointers and gpt_guid is already a pointer to struct guid. I've recompiled chain.c32 with this tiny fix (using gcc 4.4.3) and now it finds disks b...

Some OSes (e.g. Windows Server 2012 R2) fail to boot after virt-resize due to changed disk guid. To fix it, we add new APIs: part_get_disk_guid part_set_disk_guid part_set_disk_guid_random We also preserve disk GUID in virt-resize.

New API: part_set_disk_guid_random. resize: preserve GPT disk GUID. daemon/parted.c | 75 ++++++++++++++++++++++++++++++...

Two simple build fixes for libldm. Well, the first isn't a build fix as such, but a code improvement. Rich.

So last week I was wondering if XFS was still working -- even with its last on-disk structure changes -- and it _suprisingly_ worked as expected. Right, now I can finally get rid of GRUB and use Syslinux to boot my Linux on EFI from a rootfs with xfs. Shit, I have two partitions (the first one being the required ESP) so there is no way to access the other partitions since because Syslinux does not

Hello, the following patches should get multidisk access working. The syntax accepted is the following: (hdx,y)/path/to/file where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk. the other accepted syntax is using MBR's 32 bits disk signature so for example: (mbr:0x12345678,2)/foo/bar would address

In Std_utils we already extend Char and String. These commits take it a little further by extending List and adding a new Option submodule. All basically simple refactoring. Rich.

The main goal of these patch series is to implement a new API that allows to retrieve created device-mapper devices for volumes and partitions back after they have been created. As part of this patch: - required libdevmapper version was bumped to 1.02. I think it is safe because it was released more then 10 years ago; - newer version of libdevmapper allowed to simplify code base a little bit; -

This time including the first commit ...
