Extend the free space on LVM
Reading Time: < 1 minute
I had to reinstall my ubuntu 20.04 server because a boot issue became impossible to fix. After installing the OS, I found that df -lh
only give me about 200 GB of space. I had more hard drive. With a little search around, I found that the disk is mounted, but I meant to extended to be more flexible. I just want all the space there.
This post gave a pretty good description of the problem and what to do, but here is commands I used specifically. This post showed how to extend all the free space, without specifying the exact amount of space.
sudo vgs
VG #PV #LV #SN Attr VSize VFree
ubuntu-vg 1 1 0 wz--n- <2.73t 2.53t
sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
Size of logical volume ubuntu-vg/ubuntu-lv changed from <2.15 TiB (563200 extents) to <2.73 TiB (714879 extents).
Logical volume ubuntu-vg/ubuntu-lv successfully resize
sudo resize2fs /dev/ubuntu-vg/ubuntu-lv
resize2fs 1.45.5 (07-Jan-2020)
Filesystem at /dev/ubuntu-vg/ubuntu-lv is mounted on /; on-line resizing required
old_desc_blocks = 275, new_desc_blocks = 350
The filesystem on /dev/ubuntu-vg/ubuntu-lv is now 732036096 (4k) blocks long.
