LVM
LVM⚑
Usage⚑
Display the physical volumes and the logical volumes they conatain⚑
pvdisplay -m
Create new physical volume⚑
The device must have an empty partition table or if it's a partition, it should have the 0x8e identifier (for LVM). You can achieve this things with fdisk. Once ready:
pvcreate [device]
Move physical extents between physical volumes⚑
This is useful if you want an already existing LV to be on a specific PV.
pvmove /dev/sda1:1000-1999 /dev/sdb1:0-999
Create a logical volume⚑
lvcreate -n [lv name] -L [size in gigabytes]g [vg name]
Then format it and mount it if requiered.
Extend LV and filesystem⚑
To extend the logical volume and the filesystem in it use:
lvresize --resizefs --size +931GB /dev/vg/lv_home
When extending, the filesystem can be mounted, but not when shrinking.
