Hello,

I'm currently working on procedures for backup and restore of VM under OpenVZ

I'd like to understand one thing, on my first VM I had all the tree like this:

[root@srv53 private]# ls /vz/private/101
bin dev halt lib lost+found mnt proc sbin srv tmp var
boot etc home lib64 media opt root selinux sys usr

Now in all new VM, I plusque are Features large file:

[root@srv53 private]# ls /vz/private/112/root.hdd/
DiskDescriptor.xml DiskDescriptor.xml.lck root.hdd root.hdd.mnt

I'd like to return to the solution with all the files because it asks me to mount worries
my VM on another physical machine.

Have you any idea why he did create me all the tree as before?

Thank you in advance for your help.

Max

If you run df -h, and you use LVM, you will see that the running ct's have ploop devices mounted ploop***** .

Read about ploop, there is multiple good reason why it is used by default, performance & backups.
