Add p_mbr_p_type as member of type partition to describe mbr partition type. Currently we use: List.filter (fun p -> parttype <> MBR || p.G.part_num <= 4_l) to filter out logical partitions. Commit 0c396a4bce578486dfc4a38e1f8c47fd5c2836ea introduce API part_get_mbr_part_type, we could use this to know the part_type. Furthermore, we could also use p_mbr_p_type for resizing logical

Hi, OLPC's Openfirmware (OFW) implementation chokes when attempting to boot an iso created by isohybrid. The problem is that OFW's ISO-9660 support expects a partition type of 0x96 (CHRP ISO-9660, according to http://en.wikipedia.org/wiki/Partition_type). I see from

Hey all, I''m trying to figure out how to re-size physical partitions in the Dom U. I''ve read up what I can find on line and finally decided to have Logical Volumes in the Dom 0 and pass them as physical volumes for use in the Dom U. Here''s an example of what I''m doing. To start in the Dom 0 I created the LV''s with lvcreate -n guest_boot -L 100M

Hi Rich, This is v3 series to add support for resizing MBR logical partitions. changes to v2: 1. remove p_part_num 2. remove filter_parts 3. name the function calculate_target_partitions 4. remove the code to restart guest introduced in v2 changes to v1: 1. spit the patches so it's easier to review 2. fix the parted error caused by unaligned logical partitions 3. extend the

Show partition sector data and target partition sector data in debug_partition. Also, if --verbose, call debug_partition again before parted partitions.

Hey All, I my research I came across a note that a specific partition type was preferable when creating a raid 5 array. I installed my HDs and used mdadm to assemble them into a raid 5 array. I then partitioned the array using gdisk. The default partition type is "8300 Linux filesystem" for the two partitions that I created. The article I read said that a specific partition type

We lack of showing parttition type for part-list command. This patch will add support for this. Also 'parted -m' did not provide partition type info, remove code section for 'parted -m' process.

Instead of parsing 'parted' output OCaml implementation relies on the following facts: 1. The function is applicable for MBR partitions only (as noted in documentation and as function name suggests). 2. An attempt to call the function for non-MBR partition fails with "part_get_mbr_part_type can only be used on MBR Partitions" error and NULL is returned. 3. MBR partition table

Initial discussion is here: https://www.redhat.com/archives/libguestfs/2018-January/msg00188.html. v2 was posted here: https://www.redhat.com/archives/libguestfs/2018-January/msg00246.html. v3 comparing to v2 is just a rebase with slightly changed commits comments.

Hi Rich, This is v5 series to add support for resizing MBR logical partitions. please review. Thanks! changes to v4: 1. add support to resize extended partition (--resize or --expand extended partition) 2. fix the problem of deficit of 512 bytes when expanding a logical partition (this problem can be reproduced in v4 by only expanding a logical partition, without resizing any other
