Stuck with lvextend syntax

Hi

Probably an obvious one but for the life of me I can't seem to find the right syntax for the lvextend command under ubuntu 16.04.6:

someadmin@tableau-sx-01:/dev$ sudo pvs
  PV         VG               Fmt  Attr PSize  PFree
  /dev/sda5  tableau-sx-01-vg lvm2 a--  59.28g 10.02g
someadmin@tableau-sx-01:/dev$ sudo lvextend –rl +100%FREE /dev/sda5
  Path required for Logical Volume "–rl".
  Please provide a volume group name
  Run `lvextend --help' for more information.
someadmin@tableau-sx-01:/dev$ sudo lvextend –rl +100%FREE /dev/sda5 tableau-sx-01-vg
  Path required for Logical Volume "–rl".
  Please provide a volume group name
  Run `lvextend --help' for more information.
someadmin@tableau-sx-01:/dev$ sudo lvextend –rl +100%FREE tableau-sx-01-vg /dev/sda5 
  Path required for Logical Volume "–rl".
  Please provide a volume group name
  Run `lvextend --help' for more information.

As you have guessed I am trying to resize /dev/sda5

What is the "correct" syntax ?

you need a volume group to extend

lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3
Open in new window

Extends the size of logical volume "vg01/lvol01" by the amount of free space on physical volume /dev/sdk3. This is equivalent to specifying "-l +100%PVS" on the command line:

you need to use fdisk and resize2fs https://www.cloudberrylab.com/resources/blog/linux-resize-partition/

well I have only one partition and it is my boot volume - so the cloudberrylab linked procedure is a no go

Well from my trials linked above:

someadmin@tableau-sx-01:/dev$ sudo pvs
  PV         VG               Fmt  Attr PSize  PFree
  /dev/sda5  tableau-sx-01-vg lvm2 a--  59.28g 10.02g

Open in new window

So my assumption is that my volume group to extend is tableau-sx-01-vg ?

someadmin@tableau-sx-01:/dev$ sudo lvextend -L +54 /dev/mapper/tableau-sx-01-vg-root /dev/sda5
  skip_dev_dir: Couldn't split up device name tableau-sx-01-vg-root.
  Path required for Logical Volume "tableau-sx-01-vg-root".
  Please provide a volume group name
  Run `lvextend --help' for more information.
someadmin@tableau-sx-01:/dev$ sudo lvextend -L +54 tableau-sx-01 /dev/sda5
  Path required for Logical Volume "tableau-sx-01".
  Please provide a volume group name
  Run `lvextend --help' for more information.

If so what you be the command I should use ? Doesn't seem to be able figure it out...

lvextend -L +54 /dev/tableau-sx-01-vg/lvol1 /dev/sda5

guessing logical volume 1

Thanks - clearly not volume1 though
