[SOLVED] Where is my free space?

[waskaforum]

Hello

I'm moving a 1TB copy of a VM to a new server that has 7TB free but I get an error "not enough space". What am I doing wrong?

df -H in new server

root@srv105:/mnt# df -H

Hi, how are you moving the data? From where to where? Note that you have a LVM, so the root filesystem only has:

/dev/mapper/pve-root 101G 3.8G 92G 4% /

How can I reduce LVM and increase space for backups?

Proxmox 8.2.2

Why not create a Logical Volume on your LVM and format it with ext4 for your files and backups?

I'm not very good at Linux file system. Do I have to do it?

lvcreate -n vz1 -V 2TB /dev/sda3

lvcreate -n vz1 -V 2TB /dev/sda3

NO - not like that.

Like this (I believe based on your output above):

#Create addidtional LV
lvcreate -n vz1 -V 2TB /pve/data

#Then format the LV to ext4
mkfs.ext4 /dev/pve/vz1

#Then you need to mount it (temporary) or add to fstab (permanently), so maybe:
mkdir /var/lib/vz/vz1
echo '/dev/pve/vz1 /var/lib/vz/vz1 ext4 defaults 0 2' >> /etc/fstab

Then you can add in GUI under Datacenter, Storage, Add, Directory a new Storage using
the Directory /var/lib/vz/vz1 , set the Content type to include all types you require & you should be good to go.


EDIT: Make sure you have full & restorable backups before doing anything!

One more thing, you really should make sure always you have backups that are at least stored on another physical disk - not the running PVE OS disk.

Thank you! It worked!

Good for you. Maybe tag mark the threadtTitle with [SOLVED], (upper right hand corner under title).
