Resizing luks encrypted partition to fill free space

Question

I'm trying to use the full space available on my HDD (1TB, migrating from 500GB HDD).My partition is encrypted (LUKS).

I tried based on this, however lvresize seems to be not extending my partition to ~ 1TB:

sudo lvresize -l+100%FREE /dev/mapper/vg_oc2462701832-lv_root
  Size of logical volume vg_oc2462701832/lv_root unchanged from 449.47 GiB (115065 extents).
  Logical volume vg_oc2462701832/lv_root successfully resized.

My setup:

sudo fdisk -l /dev/sda
Disk /dev/sda: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00078ba5

Device     Boot   Start        End    Sectors   Size Id Type
/dev/sda1  *       2048    2050047    2048000  1000M 83 Linux
/dev/sda2       2050048 1953521663 1951471616 930.5G 83 Linux

sudo vgs -o +vg_free_count,vg_extent_count
  VG              #PV #LV #SN Attr   VSize   VFree   Free   #Ext  
  vg_oc2462701832   1   1   0 wz--n- 930.53g 481.06g 123151 238216

I've also tried to use the blivet-gui to resize the LVM (from Fedora 26 live CD), like this:

resulting in following actions:

I get the following error:

Can you ceate an additional LV in that VG? Does lvresize -l+1 work? Is there anything in the output of dmesg? — Hauke Laging, Aug 13 '17 at 12:14
sudo lvresize -l+1 /dev/mapper/vg_oc2462701832-lv_root results in: Insufficient free space: 1 extents needed, but only 0 available — Peter Butkovic, Aug 13 '17 at 21:14
creating additional LV doesn't work as well. Tried with blivet-gui, it resulted in: Insufficient free space: ... extends needed, but only 0 available. — Peter Butkovic, Aug 13 '17 at 21:17
Create a backup of the LVM metadata with vgcfgbackup and check whether its data is correct (especially the PV size). — Hauke Laging, Aug 13 '17 at 21:36
What have you done so far? Did you copy the LUKS volume to the new disk and then enlarge it with cryptsetup resize, or did you create a new encrypted volume and copy the LVM PV? What is the output of vgdisplay vg_oc2462701832 and of pvdisplay on the physical volume? — Gilles 'SO- stop being evil', Aug 13 '17 at 23:01
@Gilles outputs provided. I did a copy of disk to disk with clonezilla and afterwards followed the: https://unix.stackexchange.com/questions/320957/extend-a-luks-encrypted-partition-to-fill-disk up to step 9, where output I provided (and was suspicious, as no additional space was available) — Peter Butkovic, Aug 14 '17 at 06:20
@HaukeLaging I ran sudo vgcfgbackup with output: Volume group "vg_oc2462701832" successfully backed up. but not sure how to check whether it's data is correct :( — Peter Butkovic, Aug 14 '17 at 06:21
What's the output of lvs? It displays various attributes of the logical volumes. — Emmanuel Rosa, Aug 14 '17 at 20:22
There is a block physical_volumes {. What is the dev_size = value it contains? — Hauke Laging, Aug 15 '17 at 07:29
