NFS datastore backup

[raj]

I converted with the following command :

qemu-img convert diskimage.vmdk diskimage.raw


Then ran a backup, then restored that backup to the iscsi LVM.

Its taking 10 mins to boot a linux box now and cpu usage is much higher.

Cheers,

Raj

cpu usage on the host is about 75 to 80% and that a 2 socket 8 cores.

Hi Tom,

I am looking to have the vms on an iscsi lvm so that I can do snapshot backups.

What would be the best way to go in that direction pls.

I tried to convert the images to raw but that just makes the whole box dead slow afterwards.

Any suggestions pls?

Cheers,

Raj

Hi Tom,

I do not have these as physical machines but they are already in proxmox on a standalone box.

They used to be esxi4.1 vm.

So i moved them to proxmox as explained in earlier post.

I would like to run them in a cluster environment to have failover and I have setup a LVM on an iscsi target.

Now when i try to restore the backup of one of these vm, its not allowing me tellng me its a.vmdk.

Could you tell me or point me on how i can use the cluster with lvm on the iscsi pls.

Cheers,

Raj

which part is unclear? define a more to-the-point question - read all articles in the wiki and if something is unclear, search the forum, the web and finally ask here.

if you don´t want to go this self-service way, think of buying commercial support.

NFS does not support snapshots.

NFS support snaphosts with enough PE (256 I think) on the local VG...

Let see that :

TASK OK

The storage 'tcmsrvnfs' is a NFS server with LVM. So, it works
