LV /home reports full after extending on Arch VM

Hi everyone,

I really need help with this one.
I have an Arch VM configured for doing some programming projects, and this was the first time i configured it with LVM.
By mistake, I put only 20GB for my /home partition, and at some point I had to extend it.
I did extend it, both in the VirtualBox, and after that extended the partition, but it still shows as full. Now please check the following outputs.

Here is the output from "lsblk -e7"
NAME                  MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
sda                     8:0    0  100G  0 disk 
├─sda1                  8:1    0  500M  0 part 
└─sda2                  8:2    0 99.5G  0 part 
  ├─volgroup0-lv_root 254:0    0   30G  0 lvm  /var/lib/snapd/snap
  │                                            /
  └─volgroup0-lv_home 254:1    0 69.5G  0 lvm  /home
sr0                    11:0    1  1.8G  0 rom  

The size reports as 69.5, which is correct, the new extended size.
However check this, this is the result of "df -h":

Filesystem                     Size  Used Avail Use% Mounted on
dev                            3.8G     0  3.8G   0% /dev
run                            3.8G  1.2M  3.8G   1% /run
/dev/mapper/volgroup0-lv_root   30G   18G   11G  62% /
/dev/mapper/volgroup0-lv_home   20G   19G  3.8M 100% /home
Downloads                      821G  440G  382G  54% /home/marko/Shared
tmpfs                          774M   88K  774M   1% /run/user/1000

Still the old size, and reports as full.
Furthermore, "df -i":

Filesystem                     Inodes   IUsed   IFree IUse% Mounted on
dev                            987526     617  986909    1% /dev
run                            990107     875  989232    1% /run
/dev/mapper/volgroup0-lv_root 1966080  375888 1590192   20% /
/dev/mapper/volgroup0-lv_home 1278608  170641 1107967   14% /home
Downloads                        1000 -999000 1000000     - /home/marko/Shared
tmpfs                          198021      91  197930    1% /run/user/1000

Any help would be greatly appreciated!

Re: LV /home reports full after extending on Arch VM

Can you post the exact command used to resize the partition?

My hunch is you used the lvresize command without passing the --resizefs directive. Hence, the partition was resized but the file system itself wasn't.

Hm, I don't remember, I was referencing some online source, but it could have definitely been that I didn't pass --resizefs.
How can I remedy this now?

I'm not sure this is the best way, but try resizing the partition back to the original size. If that succeeds, then resize to the desired partition size, this time make sure to pass the --resizefs parameter.

If that doesn't work, try resize2fs on the partition. The reason I didn't suggest this intially is I'm not sure if it works on lvm.

Could you maybe, or anyone else post an explanation of what would be the preferred procedure for resizing lvs?
