I'm trying to better understand vzdump and how it does a snapshot for an openvz . the vz's are at /var/lib/vz . how does vzdump make a snapshot of a directory like /var/lib/vz/private/107 ? as I'd like to use that same method to make snapshots of then backup directories with in the vz.

thank you that is easy. is there a way to use a different port number?

I thought it was just user land. then when a new pve kernel is installed, we do not need to build a module . correct? [ AFAIR rebuilding a module was suggested in one of these drbd threads].

e100: I have a question about drbd8-utils . do drbd8-utils contain a kernel module or just the management programs?

We are using NFS running on a Proxmox 2.1 system for backups with out problems. the backup file system is ext3. our largest backups are 20GB . Is anyone having issues with nfs on proxmox ?

Can you post more details on your set up ? For instance the scripts? Also - are you using primary/primary drbd?

With ha working great for kvm on drbd I'm tempted to switch a container to kvm. this container is where we do a lot of data entry. But speed tests on our data show ct 7 times faster then kvm. The system runs debian etch. Inside the system, memory and cpu usage are low. In case someone...

why use lenny-backports? that line in sources.list should probably be removed . then wun aptitude update and install nfs-kernel-server from squeeze. I am not sure that will solve the issue. But it is better to use squeeze stable packages.
