Ajuda Estendendo o LVM

Question

Eu adicionei 30 GB de espaço a um dos meus servidores 16.04 redis que usam o LVM.

Consegui ver a unidade física, mas não consigo descobrir como expandir o disco lógico

:

root@Redis5:/dev# lvmdiskscan
  /dev/Redis1-vg/root   [      45.52 GiB]
  /dev/sda1                [     487.00 MiB]
  /dev/Redis1-vg/swap_1 [       4.00 GiB]
  /dev/sda5                [      79.52 GiB] LVM physical volume
  1 disk
  2 partitions
  0 LVM physical volume whole disks
  1 LVM physical volume

Eu tentei:

root@Redis5:/dev# sudo lvresize -l+100%FREE --resizefs Redis1-vg/root
  Size of logical volume Redis1-vg/root unchanged from 45.52 GiB (11653 extents).
  Logical volume root successfully resized.
resize2fs 1.42.13 (17-May-2015)
The filesystem is already 11932672 (4k) blocks long.  Nothing to do!

Qualquer ajuda seria muito apreciada.

    

Answer 1

Finalmente descobri isso -

sudo growpart /dev/sda 5 # extend the existing part

sudo pvresize /dev/sda5 # bring in the extra space
sudo lvresize -l+100%FREE --resizefs ORDRedis1-vg/root ## resize

    

Answer 2

Como parece que você já redimensionou a partição subjacente, você deve executar pvresize antes de redimensionar o LV.
