Backup

I did a normal snapshot lzo backup of vm 100 on the 'extra' storage (it's an lvm volume mounted at /mnt/extra)

root@proxmox1:~# ls -l /mnt/extra/dump/
-rw-r--r-- 1 root root        3966 Mar  8 16:34 vzdump-qemu-100-2014_03_08-16_30_45.log

all ok

The problem with restore:

Doing a Restore on same storage ('extra') of that backup i get the following error:

restore vma archive: lzop -d -c /mnt/extra/dump/vzdump-qemu-100-2014_03_08-16_30_45.vma.lzo|vma extract -v -r /var/tmp/vzdumptmp4460.fifo - /var/tmp/vzdumptmp4460

Reading here in the forum i tried decompressing the lzo file with:

lzop -d /mnt/extra/dump/vzdump-qemu-100-2014_03_08-16_30_45.vma.lzo

I ended up with a file as expected:

-rw-r--r-- 1 root root 10356096000 Mar  8 16:30 vzdump-qemu-100-2014_03_08-16_30_45.vma

Now if i Restore it (via GUI) it all goes well!

This is a fresh PVE installation upgraded to last from respository.

Seems something weird happens in the lzop pipe...

It seems this problem doesn't happen when using path on different drives. I was restoring on the same physical drive. Today I tried restoring on a different drive and it worked.
Might be related to the time needed to start the lzop pipe on the same device for data transfer bottlenecks?
