Problem adding directory - difference between lvm size and GUI new directory

[ezequielszurita]

Hello everyone! my name is Ezequiel and i have a big problem.
I installed proxmox in a SSD disk, but when i need make a backup of my VM i dont have space.
For this reason, i install two disk HDD of 1tb each one, and i build a LVM partition (size 300gb)

When I finally access the directory through the GUI, proxmox indicates that the partition is 7GB

attached screenshots







Try creating the lvm with different sizes (100g, 200b, 900gb) but it doesn't work, keep detecting only 7GB Additionally attached the commands you use to create the partition:

pvcreate /dev/sdc
vgcreate prueba /dev/sdc
lvcreate -n back -L 300g prueba
mkfs -t ext4 /dev/..../prueba-back

this would not have worked either, since you cannot save backup on lvm (a block based storage), only on directory based storages (dir, nfs, cifs, etc.)

When I finally access the directory through the GUI, proxmox indicates that the partition is 7GB

what exactly did you configure? please post the storage config (/etc/pve/storage.cfg)

disregard this, i missed that you created an lv on top and a filesystem

to configure, i made this steps

1)

2) add directory

3)

thats not how it works.
after you created a filesystem with 'mkfs.ext....'
you have to mount it somewhere (and add it to fstab if you want it to be mounted on boot)
e.g. with 'mount /dev/..... /mnt/mynewdisk'

then you can add a directory storage for '/mnt/mynewdisk'

Así no es cómo funciona.
después de crear un sistema de archivos con 'mkfs.ext ....'
tienes que montarlo en algún lugar (y agregarlo a fstab si quieres que se monte en el arranque)
por ejemplo, con 'mount / dev / ..... / mnt / mynewdisk'

entonces puede agregar un almacenamiento de directorio para '/ mnt / mynewdisk'

i can't

Could you show me documentation about this?

 

[ezequielszurita]

this is my archive /etc/fstab

i agree the line 4 and 5, but doesn't work

 

[dcsapak]

you have to create a directory first for the mountpoint eg. /mnt/mydisk with 'mkdir'

mkdir /mnt/mydisk
mount /dev/backups/back /mnt/mydisk

this is standard linux sysadmin staff, a tutorial for partitioning and mounting can easily found via google, e.g. : https://www.digitalocean.com/commun...partition-and-format-storage-devices-in-linux
