Increase size of Proxmox VE 1.8 Backup folder

[bimbo]

I want to make a backup of a KVM VM to migrate to Proxmox 2.0.

The problem is that every time I create a Directory Storage folder the size is limited to 10% of disk space independent of the folder used.

How or where do I change this limit?

Regards

David

the size is determined by the size of the partition.

pls post:

df -h

and the path you use.

I see.... so i must change the pve-root

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/pve-root   95G  9.4G   81G  11% /
tmpfs                  12G     0   12G   0% /lib/init/rw
udev                   10M  620K  9.4M   7% /dev
tmpfs                  12G     0   12G   0% /dev/shm
/dev/mapper/pve-data  811G  266G  545G  33% /var/lib/vz
/dev/sda1             504M   32M  447M   7% /boot

How can I do it safely

total size is 95 GB, currently you use 9,4 GB and 81 GB is free.

11 % is used, 89 % is free.

hope its clearer now.

Tom you are right...the problem is when I do the backup of a KVM Image I get an error of insufficient disk space.

Another doubt that I have is on the difference between pve-root and pve-data what is used on what, how pve-root is smaller that pve-data...

pve-data is mounted on /var/lib/vz

that means, all directories under /var/lib/vz are there. Its (mainly) used for containers and VM´s.

 

[bimbo]

For the interest of the audience

pve-root=20G
pve-data=100G


I found a way (not risk free!!!!! So use at your own risk!!!)

Say you have
pve-root=20G
pve-data=100G

and you want
pve-root=60G
pve-data=60G

1st check if usage of pve-data is >60GB

if not we can proceed!!!

umount /var/lib/vz

unmount filesystem

e2fsck -f /dev/mapper/pve-data

Check the filesystem

resize2fs /dev/mapper/pve-data 60G

Resize the volume to 60G

lvreduce -L-40G /dev/mapper/pve-data

To reduce the logical volume pve-data with 40GB (100 – 60 = 40 GB)

mount /var/lib/vz

To remount the file system mounted on /var/lib/vz


Now pve-root

lvextend -l+100%FREE /dev/mapper/pve-root

Extend to 100% free space

resize2fs /dev/mapper/pve-root

Resize the filesystem

now df -h should shown the new sizes

Thanks all
