Hello,

I'm have an issue trying to restore an lxc.
Code: 
extracting archive '/mnt/pve/nfs-pve/dump/vzdump-lxc-3117-2015_10_31-14_11_22.tar.lzo'

TASK OK

the target has plenty of space:
Code:

tank/lxc                     14.9G  6.68T   208K  /tank/lxc

any suggestions to get the restore to work?

how much space did you assign to the container?

it is strange - under resources in pve I do not see any disk size setting . at a all the lxc's i checked.

I manually migrated the lxc, and sure enough in the conf file:
rootfs: pve:3117/vm-3117-disk-1.raw,size=36M

that is strange..
 
Is that a backup from beta phase? (there was a bug). To workaround, you can restore on the command line,
and specify storage and size using the rootfs parameter.

# pct restore <VMID> <archive.tar.gz> --rootfs <storage>:<sizeInGB>

does that work

The backup was made today.

Originally I think the system was restored from another backup 3-4 weeks ago. I'm not sure if the restore was from an openvz or lxc backup.

I was able to use rsync to move the image from old system to new , and moved the .conf file to new node.

So I'll try the pct restore command later .

Thank you for the help.
 
Re: restore lxc issue: Cannot write: Disk quota exceeded *solved*

So to prevent this check for M where there should be a G at rootfs , then edit files to fix.
Code: 
grep rootfs /etc/pve/nodes/*/lxc/*.conf

In case there is a M in a backup conf file for rootfs , then use the pct command as Dietmar suggested
Code: 
pct restore <VMID> <archive.tar.gz> --rootfs <storage>:<sizeInGB>

I ran in to another backup with what seems like same issue, so tried:
Code: 
pct restore  3113 /mnt/pve/nfs-pve/dump/vzdump-lxc-3112-2015_10_31-21_40_53.tar.lzo  --rootfs  lxc-zfs,size=4G  
400 Parameter verification failed.
storage: storage 'local' does not support container root directories
pct restore <vmid> <ostemplate> [OPTIONS]
so I wanted to restore that to storage lxc-zfs . I think the command was set correct to do that?

I had local storage set to NO containers. after adding containers to local storage the above command seemed to work.

Code: 
pct restore  3113 /mnt/pve/nfs-pve/dump/vzdump-lxc-3112-2015_10_31-21_40_53.tar.lzo  --rootfs  lxc-zfs,size=4G

Total bytes read: 8045496320 (7.5GiB, 74MiB/s)
Detected container architecture: amd64

However I could not find the rootfs. nothing at /var/lib/vz/images or /tank/lxc .

and the config file dies not have a rootfs:
Code: 
# cat /etc/pve/lxc/3113.conf
#ubuntu vivid lxc template used to make this.
#
#zm from ppa
#
#had to manually add cams since mysql teble  was different.
arch: amd64
cpulimit: 2
cpuunits: 1024

onboot: 1
ostype: ubuntu
swap: 512

maybe I did something wrong?
 
so the zpool was restored to:
Code: 
Filesystem                                  Type      Size  Used Avail Use% Mounted on
tank/lxc/subvol-3112-disk-1                 zfs       8.0G  8.0G     0 100% /var/lib/lxc/3112/rootfs

I'll delete that as root disk is small.
for now I'll manually restore and setup.

Let me know if more testing is needed or If I entered the command incorrectly.
 
I tried again to restore from pve web page, Made sure I chose the correct target - lxc-zfs , instead the restore went to local.

Another issue is that the system was set to use 8G . It actually had over 8G used. Hence the over quota issue.

the root disk on original system was a directory /pve used in pve storage as 'pve':
Code: 
rootfs: pve:3112/vm-3112-disk-1.raw,size=8G

the zpool got created as tank/lxc/subvol-3113-disk-1 , mountpoint is /var/lib/lxc/3113/rootfs

The correct format for the rootfs parameter is

--rootfs lxc-zfs:4

just tested,
Code: 
pct restore  3113 /mnt/pve/nfs-pve/dump/vzdump-lxc-3112-2015_10_31-21_40_53.tar.lzo  --rootfs lxc-zfs:4
400 Parameter verification failed.
storage: storage 'local' does not support container root directories
pct restore <vmid> <ostemplate> [OPTIONS]
that was with 'local' storage not allowing containers.
 
with local allowing containers.
note sys4 does not use zfs .
the backup was made on sys4 .
Code: 
sys4  /var/lib/vz # pct restore  3113 /mnt/pve/nfs-pve/dump/vzdump-lxc-3112-2015_10_31-21_40_53.tar.lzo  --rootfs pve:40

so I was able to restore and increase rootfs size.

again test containers disabled on local storage. I did so because this system is different in that it does not ues zfs.
Code: 
sys4  /var/lib/vz # pct restore  3114 /mnt/pve/nfs-pve/dump/vzdump-lxc-3112-2015_10_31-21_40_53.tar.lzo  --rootfs pve:40
400 Parameter verification failed.
storage: storage 'local' does not support container root directories
pct restore <vmid> <ostemplate> [OPTIONS]
so using a --rootfs , currently containers need to be enabled at local storage.

and
after making a pct with 40G , I did a backup, and was able to restore to the lxc-zfs storage at sys3 , without local storage enabled.
 
OK, I finally found the correct syntax - try:

# pct restore 3114 /mnt/pve/nfs-pve/dump/vzdump-lxc-3112-2015_10_31-21_40_53.tar.lzo --storage lxc-zfs --rootfs 40

use --storage to specify the storage
pass the size in GB to --rootfs
