Resize disk LVM

Dit zijn de stappen:

• Vergroot de disk via de GUI, bijvoorbeeld van 12Gb naar 24Gb
• parted /dev/vda
• (parted) print

(parted) print                                                            
Model: QEMU QEMU HARDDISK (scsi)
Disk /dev/sda: 25.8GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

• (parted) quit
• Bepaal het physical volume

root@pdnswhpdcsw1:~# pvs
  PV         VG              Fmt  Attr PSize   PFree
  /dev/sda5  vg-root-install lvm2 a--  <11.76g    0 

• Resize het logical volume

root@pdnswhpdcsw1:~# pvresize /dev/sda5
  Physical volume "/dev/sda5" changed
  1 physical volume(s) resized or updated / 0 physical volume(s) not resized

• Bekijk het vogical volume

root@pdnswhpdcsw1:~# lvdisplay 
  --- Logical volume ---
  LV Path                /dev/vg-root-install/root
  LV Name                root

  LV UUID                Ew6hJI-33MH-30nU-ZCAv-bLu2-CZNO-NKiYLm

• Resize het logical volume met de resizefs optie

root@pdnswhpdcsw1:~# lvresize --extents +100%FREE --resizefs /dev/vg-root-install/root
  Size of logical volume vg-root-install/root changed from 11.55 GiB (2957 extents) to 23.55 GiB (6029 extents).
  Logical volume vg-root-install/root successfully resized.
resize2fs 1.44.5 (15-Dec-2018)
Filesystem at /dev/mapper/vg--root--install-root is mounted on /; on-line resizing required
old_desc_blocks = 2, new_desc_blocks = 3
The filesystem on /dev/mapper/vg--root--install-root is now 6173696 (4k) blocks long.

• Doe hierna de controle met df -h van het volume.

root@pdnswhpdcsw1:~# df -h .
Filesystem                          Size  Used Avail Use% Mounted on
/dev/mapper/vg--root--install-root   24G   12G   12G  51% /
