You cannot directly move and import an OpenVZ Container from Proxmox 3.x to the new LXC Container in Proxmox 4.x.

Please refer to the following guide what you have to change:

How can i increase that partition becouse it is only 100 GB ... And by entrire Containter have 150 Gb and i can not upload and restore,

 

[LnxBil]

What partition and why is it only 150 GB?

Please post more information on your system.

 

[didraro]

My Local - vz dump / backup file / iso image / containter template have just 100 GB , and bu backup file have 143 GB .

So how can i do to increase that ? So i can be able to upload it and restore .

When i try to restore i receive error :

closing file '/var/log/pve/tasks/active.tmp.25001' failed - No space left on device (500)

 

[didraro]

Please can someone tell me what can i do ?

 

[LnxBil]

Yes, there is no space left on the device, the description is correct.

Please also post your /etc/pve/storage.cfg:

cat /etc/pve/storage.cfg

(Please use CODE-Tags [+]-symbol in the tool bar - also please edit your previous post, it is almost unreadable)

 

[didraro]

root@didraro:~# cat /etc/pve/storage.cfg
dir: local
path /var/lib/vz
content iso,vztmpl,backup

lvmthin: local-lvm

[didraro]

anybody can help me ?

 

[LnxBil]

I don't want to be rude BUT:

If you want to have instant response and direct help for your problem: Pay someone to do it!! You will not get an answer faster by asking if someone can help. This is forum, so it is asynchronous communication, not synchronous one. If you want to talk to someone, buy a premium subscription and ask the competent guys from Proxmox for help or hire someone to help you.

 

[LnxBil]

So that you're not too frustrated, here is your solution:

According to your storage.cfg your backups go to /var/lib/vz which is in your configuration on /, where you have only 76 GB free. Easiest thing to do would be to resize your root partition (haven't tried the command, yet it should look like this:

lvresize --size +100G --resizefs pve/data

 

[didraro]

root@didraro:~# lvresize --size +100G --resizefs pve/data
Ignoring --resizefs as thin pool volumes do not have filesystem.
Insufficient free space: 25600 extents needed, but only 4052 available

- doesn't work.

 

[LnxBil]

oh, my mistake:

lvresize --size +100G --resizefs pve/root

 

[LnxBil]

If that also does not work because of

Insufficient free space: 25600 extents needed, but only 4052 available

Then you'll have to free space, e.g. delete VMs

 

[didraro]

What do you mean delete VMs ?

Beocuse my entire VirtualMachines does not use all the space.

 

[didraro]

My Local LVM ( Disc Image , Container ) - have 2.61 TB in total , used : 484.33 GiB , the local ( VzDump backup file , Iso Images , Container Template ) - 94.37 Gib , Used : 13.76 Gib.

and the backup wich i wana to upload and restore have 143 Gib .

I can not even upload or restore it .

 

[LnxBil]

I don't know what else I could add ... it's your error message that says that you do not have enough free extends in your LVM, not mine. Your pvs command states the same.

The problem is that pve/root is thick provisioned and you have most of your free space in your thin volume encapsulation. You could resize or just create another volume, like it is described here

https://pve.proxmox.com/wiki/LVM2#Create_a_extra_LV_for_.2Fvar.2Flib.2Fvz

If you have data in /var/lib/vz use another mount point for your volume and add it to your GUI. You can then upload there.
