[linux-lvm] Extending LVM and SomeQuestion ..

[Vahric MUHTARYAN]

Hi Everybody , 

I created Volume Group and I added 2 disk into VG. That's ok problem is; 

I checked Howto http://tldp.org/HOWTO/LVM-HOWTO/recipeadddisk.html 

it's using only vgextend ( not lvextend ) to extend size of Volume Group and
file system ?! Does it true ?! Do I have to use lvextend ?! don't I ?! 

and 

it's look like ext3 not good choise for resizing filesystem because ext2,
ReiserFS , xfs , jfs have more tools for extending ?! 




Best Regards ..

With vgextend you grow a Volume Group (think about it like a resizable disk),
with lvextend you grow a Logical Volume (like a resizable partition).

You can resize an unmounted ext3 with resize2fs (the ext2 resize tool).

The steps you need to carry out for growing your VG and LV(s) are:

# vgextend YourVGName /dev/dsk1 /dev/dsk2 # You did that already, right ?
# lvextend -L+WhateverGrowths /dev/YourVGName/YourLVName
# resize2fs /dev/YourVGName/YourLVName # Presumably this is ext2/3

Use the respective tools to resize any other filesystem type
(eg, resize_reiserfs).
