Re: [PVE-User] Moving virtual machine from CE 6.X to latest enterprise edition, advice requested

[Joseph John <jjk.saji@gmail.com>]

Hi ,
Thanks for the advice
I tried first with a CIFS share , checked by accessing it from other
machines . created CIFS share (Left hand side of menu, Data Center,
Storage) ,
Now when I go to the VM , backup option , and click backup I can only see
the local storage, I am not able to see the CIFS share which I created

Similarly I did with NFS server and shared directory , checked it by
accessing it from other hosts. Created NFS share (Left hand side of menu,
Data Center, Storage).
This also when I go the the VM, backup option and click back I can only see
the local storage , not the NFS or the CIFS storage which we created
earlier . The prox mox version is 6.3-3.

But when I give a df-h , I get the results

oot@server-1:~# df -h

tmpfs                                     76G   13M   76G   1% /run

So from the df -h , we can see the CIFS and NFS, but through the web
interfaces, backup option do not show them in the drop down menu.
I am thinking in this situation, to make use command line and run the
backup so that I can specify the location (cifs or nfs share) to which I
can  copy the disk image
I will be posting another thread on requesting on how to use command line
to  take backup of VM images



Thanks
Joseph John
