[Feature Request] Add support for LVM with saveparts and restoreparts #148
Description
In my PC I'm using LVM and I'm unable to use the saveparts and restoreparts functions in Clonezilla.
Clonezilla live version tested:
3.2.2-15(latest stable)3.2.3-11(latest testing)
This is my disk (simulated in VirtualBox for simplicity but same results with real machine):
$ sudo sgdisk -p /dev/sda
Disk /dev/sda: 62914560 sectors, 30.0 GiB
Model: VBOX HARDDISK
...
Number Start (sector) End (sector) Size Code Name
1 2048 1050623 512.0 MiB EF00 EFI System
2 1050624 62912511 29.5 GiB 8E00 Linux LVM
My LVM partitions:
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 30G 0 disk
├─sda1 8:1 0 512M 0 part /boot/efi
└─sda2 8:2 0 29,5G 0 part
├─vgubuntu-root 254:0 0 28,5G 0 lvm /
└─vgubuntu-swap_1 254:1 0 980M 0 lvm [SWAP]
Then I run Clonezilla:
$ sudo ocs-sr -q2 -c -j2 -z9p -i 0 -sfsck -senc -p true saveparts BACKUPPATH sda1 vgubuntu/root
Setting the TERM as linux

use_dev_list_cache is set as no. Do not prepar device name cache files in /tmp/ocs-cache//...

Why is Clonezilla shutting down my LVM?
Ok, if I'm using savedisk or restoredisk maybe is the right choice, but I need to use saveparts and restoreparts.
I'm missing some options (usually I'm using beginner mode, so is possible) or there isn't an option to avoid shutting down LVM?
Instead if I run partclone directly it works perfectly.
These are the commands i use, in case anyone has the same problem.
