LXC restore error in 4.0-48

[klauskurz]

Hi!

I did a container backup and then a restore.

There is the following error:

Formatting '/var/lib/vz/images/1002/vm-1002-disk-1.raw', fmt=raw size=10485760

Is there anything that I can do here, to make the restore work?

Best regards

Try to specify/overwrite the container size with --rootfs option:

# pct restore 1002 /mnt/pve/h01-backup-01/dump/vzdump-lxc-10001-2015_10_18-12_38_32.tar.lzo --rootfs local:4

which use 4GB on storage 'local'.

I wonder why the original size is only 1GB? It this a backup from beta1?

Thank you for the quick and perefect answer. The restore now worked.

# pct restore 1002 /mnt/pve/h01-backup-01/dump/vzdump-lxc-10001-2015_10_18-12_38_32.tar.lzo --rootfs local:4

I did some investigation:

The backup was from: 2015_10_18-12_38_32. Never had a beta installed.

# tar -xf /mnt/pve/h01-backup-01/dump/vzdump-lxc-10001-2015_10_18-12_38_32.tar.lzo ./etc/vzdump/pct.conf
# cat ./etc/vzdump/pct.conf

arch: amd64
cpulimit: 4
cpuunits: 1024
hostname: v02
memory: 2048
nameserver: 172.18.1.1
net0: bridge=vmbr0,hwaddr=0A:94:64:FE:38:B1,name=eth0,type=veth
ostype: ubuntu
rootfs: local:10001/vm-10001-disk-1.raw,size=10M
swap: 512

There is indeed a "size=10M"

There was another backup, just after the first:

# tar -xf /mnt/pve/h01-backup-01/dump/vzdump-lxc-40008-2015_10_18-12_40_40.tar.lzo ./etc/vzdump/pct.conf
# cat ./etc/vzdump/pct.conf

arch: amd64
cpulimit: 8
cpuunits: 1024
hostname: v08
memory: 8192
net0: bridge=vmbr0,gw=172.18.1.1,hwaddr=AE:E5:10:14:76:73,ip=172.18.1.18/24,name=eth0,type=veth
ostype: ubuntu
rootfs: local:40008/vm-40008-disk-1.raw,size=4G
swap: 8704

Here the size seems to be OK.

Please let me know, if you need more debugging here.
