Hello Fabrizio,

first of all keep in mind that PBS is not production ready yet.

To answer your question yes it's possible to import a datastore to another
new-installed PBS server regardless of the filesystem used. Some manual
steps may be required but we did that in our test enviroment.

Hi,

I don't think we can retrieve this information from balloon driver

from qemu monitor ->

# info balloon
balloon: actual=32768 max_mem=32768 total_mem=32170 free_mem=14111
mem_swapped_in=0 mem_swapped_out=0 major_page_faults=48300
minor_page_faults=4492802887 last_update=1598455555

Objet: [PVE-User] Show memory usage w/o buffer/cache in VM summaries?

Dear all. 

the memory usage bar in the VM summaires in PVE (6.1-3) shows "active" 
memory including caches, which is in practice misleading. E.g. this system 

$ free -m
total used free shared buff/cache
available
Mem: 7821 4778 177 51 2864
2738
Swap: 3276 123 3153
$ 

is shown as using 7.46 GB memory, in red warning color, since this number
exceeds 90% of the available 8 GB. However IMHO the almost 3 GB memory used
as buffer/cache are irrelevant as they will be freed as soon as they are
required by applications. Hence I'd rather see the bar showing me only 4.8
GB of used memory. 

Is that achievable? The guest OS is CentOS 7.x. The qemu gest agent is
installed. 

Cheers, Frank

Hello.
I hope that my post is not off-topic, but i can't see a pbs-user list.
I would like to setup a production PBS, using a clustered storage (cephFS,
petasan, mooseFS or similar) for repository, and a separate physical host as
a server.
If my PBS server crashes (but not the cephFS or mooseFS repository), can I
import the repository in another new-installed physical PBS server ? 

Thanks, Fabrizio
