how to resize local storage

[Janvier Rwakagabo]

Hello,

How can i resize my local storage of pve (root), to a bigger size.
From attached screenshot, i want to add space on local (pve-01), which has a space of 109.74GiB and increase to a higher space.


Regards,

Janvier R.

Hi,
before you start, I recommend having a working backup available (just in case).

Note that the local storage by default is just a directory storage. So if you resize the root filesystem, that directory will have more space available as well. The root filesystem resides on the logical volume pve/root. If you have free space on the volume group pve you can use lvextend pve/root -L+<SIZE><UNIT> (e.g. 100G for <SIZE><UNIT>).

You'll also have to resize the filesystem itself. I'd recommend booting from a live CD to do it. Then running resize2fs /dev/mapper/pve-root should do the trick. If you're feeling lucky, you can also run the command without a live CD to do an online resize.

Interesting ... but how do i create a new volume? I have 100GB on pve/root and i think that the rest of 900GB are not used at all.

root@proxmox:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 16G 0 16G 0% /dev
tmpfs 3.2G 1.3M 3.2G 1% /run
/dev/mapper/pve-root 94G 66G 24G 74% /
tmpfs 16G 49M 16G 1% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
/dev/fuse 128M 16K 128M 1% /etc/pve
tmpfs 3.2G 0 3.2G 0% /run/user/0

Thank you.

My guess would be you are using the defaults where nearly all of the 900GB are used for your "data" LV thin-pool aka "local-lvm" storage. Check with the vgs and lvs commands whats going on with your LVM.
