when i have hecked the lvm groub i found

when i run the backup in the local storage , there is no probleme .

i think the probleme is the falloing

Free PE / Size 1 / 4.00 MiB


how i can resize it ?

.

I have fixed the probleme by reducing the Lv volume , here is a small howto , in my case i have HDD size 203Gb with the parition /dev/pve/lv1

#Stop all vm machine
/etc/init.d/vz stop

# unmout the partition vz
umount /var/lib/vz

#check the filesystem before reduce (required)

e2fsck -f /dev/pve/lv1

#resize te file system (in my case have 203Gb total disque , so i have used just 190Gb , 13 will be reduced )

resize2fs /dev/pve/lv1 190G

lvreduce -L -13G /dev/pve/lv1


#check the file system again
e2fsck -f /dev/pve/lv1

# mount hte vz partition again /var/lib/vz
mount /var/lib/vz

# check the size
df -h

now we can test the backup again
