...d. This series add support for resizing logical partitions. v2: 1) Add 3 variables to describe relationship of logical and extended partitions: - partitions flat list of primary partitions (as now, the global 'partitions'). extended partitions is essentially primary partition - logical_partitions flat list of logical partitions - extended_partition one MBR extended partition 2) reserve enough size when resizing logical partitions Original patches by Hu Tao at: https://www.redhat.com/archives/libguestfs/2014-October/msg00238.html Chen Hanxiao (11): resize: move loop check from...

For MBR, logical partitions laid inside extended partition. Add 3 variables to describe this: - partitions flat list of primary partitions (as now, the global 'partitions'). extended partitions is essentially primary partition - logical_partitions flat list of logical partitions - extended_partition one MBR extended partition Signed-off-by: Chen Hanxiao <chenhanxiao@cn.fujitsu.com> --- resize/resize.ml | 37 +++++++++++++++++++++++-------------- 1 file changed, 23 insertions(+), 14 deletions(-) diff --git a/resize/resize.ml b/...

In current virt-resize, only primary partitions(including extended partition) are supported. They are collected in an array for resize operations. Logical partitions are not supported. This series add support for resizing logical partitions. v3: 1) rewrite partitions/logical_partitions/extended_partition section by the comments from Rich and Pino. 2) in 03/11 introduce logical_align for reserve enough space when resizing logical/extended partitions. v2: 1) Add 3 variables to describe relationship of logical and extended partitions: - partitions flat list of primary par...

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

Hi Rich, This is rebase of v5 series. Meanwhile, I found a bug when shrinking partitions, and the fix is incuded in this version (patch 2). Regards, Hu 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

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
