Expanding LUKS container's Logical Volume on btrfs Filesystem after cloning to larger drive:

English Install/Boot/Login
1

Hello, I have a Lenovo M57-p desktop. I recently acquired a 1 TB Western Digital blue label SSD drive. I have attached the drive as secondary (in place of cd/dvd) then performed an extended test (with GSmartControl), the test completed without error. Then I tested the 160 GB drive hosting openSUSE TW (with GSmartControl), the test completed without error. Then I used the latest stable Clonezilla 3.1.1-27 to duplicate the original 160 GB platter drive to the newer 1 TB drive (drive to drive duplicate with existing partitions). I am now able to successfully boot and load into KDE with the 1 TB drive (desktop is much faster now).

The issue I am having is with expanding the LUKS containers btrfs filesystem, system-root (/sda2) LV. I am able to extend the /dev/sda2 partition with Gparted seemingly with no issue except that the Titlebar > Partition > Check button is greyed out. The output of lsblk -f

As you can see I was able to rename the LUKS container but I have not modified anything that I am aware of regarding the UUID:

Passing: btrfs filesystem resize max /mnt as root does not seem to work, it reports as follows.
Resize device id 1 (/dev/mapper/system-root) from 142.52GiB to max

Is this because system-swap is in the way of system-root i.e. (254:1 above 254:2)? I’ve been trying to review ion this for a number of hours now and feel jammed up. How can I increase the system-root LV size most easily in this situation?

I have include a screenshot of GParted displaying /dev/sda partitions.

man lvresize

lvresize -L +200G system/root

or whatever size you need.

Please, post computer text as preformatted. You do know how to do it - why do you do it only for some content and not for the other?

And you also do include the command within the copy past sometimes (e.g. with the cat /etc/fstab) , but other times you say things like

Please do all the same: include the line with the command (and still better that line complete with the prompt) up to and including the line with the next prompt (which will signal the output is complete) and of course within a Preformatted text paragraph.

Thank you for your responses on this, I am not very experienced with the composer as you see. After my initial posting on this topic I was able to extend the Logical Volume. Earlier morning before reviewing and then responding here now by passing: lvextend -L +100%Free /dev/system/root I was then able to then extend the filesystem by passing:

btrfs filesystem resize max /mnt
Resize device id 1 (/dev/mapper/system-root) from 924.98GiB to max

I am able to see that the Logical Volume and the btrfs filesystem have been expanded.

1. In looking at man lvresize and man lvextend what is the largest difference between lvresize and lvextend?
2. Passing:

4. How large of a concern are the “File descriptor” messages shown in 2. and 3. above?

-Thanks

lvresize can reduce the size.

You can ignore them.

Thank you once again for your input on this. I would like to note that initially while renaming the LUKS container name I did attempt to change the drives UUID in /etc/crypttab (After creating a cloned backup medium) with no success. The machine would stall while kernel loading (a start job is running)…

1. Is there any sort of benefit to rename any of the mediums UUID’s here?
2. After renaming the mediums name, after powercycling, asked for a passphrase twice. Firstly at grub2 menu and secondly before kernel volume load. Passing: sudo update-bootloader --refresh then powercycling has returned machine state to passphrase being asked/required only once prior to grub2 able to execute boot cycle. Is this a somewhat normal occurrence are you aware? Is this as secure in your view as two separate passphrase required?
3. Do you know how to revert back to two separate passphrase required instances during machine boot cycle?

-Thanks
