Hello everyone,

I have a problem with backup/restore procedure from PVE 2.2 to PVE 3.3.

On the same server I make a final backup for all VM's. I replace the old boot disk, and install a new one and after I install PVE 3.3-1 with no problems.
I mount the backup disk, and I try to restore the VM's from backup.

this is the output:

Code:

I have a new server that we are testing Proxmox on:

Dell R815 - 4x 16c @ 2.5GHz CPU, 1TB RAM, 6x 600GB HDD.

Is it possible to create a VM with more than 512GB through the GUI or can i only do it by modifying the VM file through the CLI?

Thanks

Cleanup and unneeded services after upgrade to 3.3

We recently upgraded a local installation to PVE 3.3 and had an issue with the final cleanup step of the upgrade script, so we had to repeat the process and avoided that part.
In order to cleanup the system and deactivated services we don't use I would appreciate if anyone could confirm:

- Bacula... service is not running, but can that be safely deinstalled or are any parts still used by the scripts?
- Apart from Apache, what other large size package is worth removing?
- PVECluster Service, can we stop it if we have no clustering? How as it's not stoppable from the web panel?
- iSCSI services report some errors on boot. Again we don't use it, can we remove it or make sure services are not running till we need them?

Thanks.

Hello,
we just bought 3 HP Proliant DL380 Gen9 on which we would like to install and purchase Proxmox but we are not able to do it. During the setup Proxmox can't detect our 3 SATA discs that are plugged on the RAID Controller HP SmartArray P840 . The only one partition that detects is the iLO which is ~512 mb instead 3x3TB. This happens We already switched BIOS from UEFI to Legacy mode.

We tried Proxmox 3.1 and 3.3.

Is there anything that could we do?

Thank you in advance!

Problem with usb passthrough

Hi,


I use Proxmox 3.3 on a N54L MicroServer.
I added a vm adding usb passthrough:
usb0: host = 2-1


On the usb port, there is a key usb dvb (August DVB-T205). In vm (debian 7 or centos 7), I installed tvheadend. The result is very bad. I have a lot of dropped frames.

this log Proxmox often appeares:
January 12 10:24:30 p.m. Proxmox kernel: [1032.577223] usb 2-1: reset high-speed USB device using ehci number 4-pci
January 12 10:24:30 p.m. Proxmox kernel: [1032.795122] usb 2-1: reset high-speed USB device using ehci number 4-pci
January 12 10:24:30 p.m. Proxmox kernel: [1032.795122] usb 2-1: reset high-speed USB device using ehci number 4-pci

and log tvheadend:

Using the qemu command info usb, usb 2 speed appears:
1.1 Device Port 1 Speed 480 Mb / s, Product RTL2838UHIDIR


Still, I really feel that the flow rate is flanged. To be sure that the problem is not from installation, I installed the 3.10 kernel on Proxmox (for the dvb drivers) and tvheadend. And the resustat is good.


I wanted to test the flow rate with the command hdparm -t. I have an average of 8 MB / s, while on Proxmox I to 22 MB / s.
is there anything I can do to use the usb passthrough normally?

Thank you and i'm really sorry for the "google traductor" English.

I burned the ISO to a blank DVD. THen I tried booting into the DVD and all I see is a black screen with a flashing cursor. I left it for 30 minutes and nothing changed.

Is this a common issue? I don't even get to the part when I press ENTER.

Update: I just checked the MD5 sums and they match.
Update: I'm now downloading 3.1 (instead of 3.3) and trying that....nope still the same screen.

Issues with backup / vzdump

Hi everybody,

we got a backup job which could not finish (disk full). The perlscript stayed pending (shouldn't we have a timeout here?). Furthermore other sheduled jobs got started cueing up with no chance to ever get processed. In my oppinion there should be a mechanism (semaphore or similar) to prevent backup jobs from starting before older ones get processed.

How can we stop the processes which are left over? We get these remaining artefacts:
173978 ? Ds 57:40 task UPID:Prox-main-2:0002A79A:34F5E8FA:549933C2:vzdump::root@pam:

Cant kill them w kill -9

Any advice?

web gui only problem - cluster disconnected

Hi,
I am experiencing another problem with gui. I run unregular backup of one of my vm during the night and it shows task ok. But the task seems still active in the tasks part.
Moreover my cluster seems to be disconnected via GUI. Another servers are red and all vm are shown just like a numbers. But on the summary page of every node I can see changing values of cpu utilization and so on.
Pvecm nodes and pvecm status shows no problem, I can write to /etc/pve, all storages are ok and restart pveproxy on all nodes does not help. I can not find any clues in logs. I am running pve 3.2-2 on all nodes.

Any advice how to restore cluster in the gui?

Hi,

Running the latest Proxmox VE 3.3-143 kernel 2.6.32-35-pve. Adaptec 6805 RAID card installed all went well it's just when I logon to check the RAID via the web interface MaxView Storage Manager, I get "No controllers were found in this system.". I understand that the latest drivers for the Adaptec 6805 RAID card are already part of the kernel. What must I do to get the MaxView Storage Manager to see the controller?

Questions on new Proxmox + Ceph Install

I am a bit of a newbie and have a couple quick questions on a new install. I have 3 Dell Servers with PERC 730 RAID controllers. Attached to the RAID controller I have 6 4TB drives all setup as individual RAID 0's for the OSD's. What is the recommendation for the following RAID controller settings?

Read Policy: Read Ahead or OFF?
Write Policy: Write Through or Write Back?
Force Write Back with battery: Yes or No?
Disk Cache Policy: Enable or Disable?

I have four 1G ethernet adapters. I was planning on bonding 2 into separate switches for the cluster/control network (untagged). I was then planning on bonding 2 for the VM networks (tagged). Lastly, 2 10G ethernet adapters bonded together for the ceph storage network (untagged).

In regards to the networking model, is Open vSwitch recommended over the default Linux networking setup? Can both OVS and Linux be used? For example, OVS for VM networks and Linux bonding for control and storage network?

Is there any issue running storage network on a VLAN tagged interface?

Thanks for your comments in advance!

Best regards,
Eric

Multiple clusters in the same subnet - pveproxy locking up

We have a PVE3.3 cluster that has ben running well. Recently we added a second PVE3.0 cluster to run some VM's that will not run on newer KVM.
Both clusters share the same management network, but have different IP addresses.

Ever since adding the second cluster we have experienced pveproxy locking up on our PVE3.3 cluster.

The only thing I can think of is that the cluster communications from the second cluster are somehow messing with the first one. Does each cluster have it's own multicast address ?

What else could be causing pveproxy to lock up ?

Creating a cluster with different versions

Hi All

I have a Proxmox node that I inherited, with about 25 VMs on it, and Im in the proccess of putting it into a cluster.

Its running a rather old version of proxmox and has not been upgraded.
(Version 2.3-13)

Ive installed two new copies of Proxmox to add to the nodes, and they are 3.3-2

Now, I have not been able to get clarity on this, Can I add them to one cluster, move the VMs across to the new nodes, and then do an upgrade of the old node? Or do I need to Upgrade the old node (which makes me worry a bit) then add them to the cluster and then upgrade.

Kind regards

Possibly got hacked: How to identify listening process

January 13, 2015, 11:27 pm
$

I have a standard vmbr0 setup with only containers that use venet devices.

One container with it's own IP address has a webserver where I detected that it answers requests with a javascript redirect and can act like a proxy to the webserver itself.

I thought and hoped only the container is infected and created a new one and changed IPs. But the problem is there. I then completely shutdown the container associated with that IP address.

But if I do web requests to the now offline container it still responds and returns a small HTML and javascript snippet from time to time. If not, it still sends 302 redirect headers.

So I guess it must be the host that is infected. Of course I cannot trust any command in that case (netstat, lsof; checksecurity, chkrootkit, rkhunter). They don't show anything listening on port 80. Of course there is the apache for proxmox GUI itself. But I guess it does this differently. The system is up-to-date apt-wise and the problem persists after rebooting.

Do you have any tips or recommendations how to further investigate? I would like to get to know more before installing everything from scratch and not knowing how they entered the system.

*** UPDATE

"They" replaced spiceproxy with a version of their own that acts as an open proxy. Firewall prohibits port 3128 but they managed to keep it open.

Drbd on lvm - resize pv

Hi,
I have create a cluster with two proxmox node that use a mirroring storage built with drbd (I use this guide (http://pve.proxmox.com/wiki/DRBD to create a shared storage).
My drdb file conf r0.res is this:
resource r0 {
protocol C;
startup {
wfc-timeout 10;
degr-wfc-timeout 10;
outdated-wfc-timeout 10;
become-primary-on both;
}
net {

max-epoch-size 8192;
allow-two-primaries;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
after-sb-2pri disconnect;
unplug-watermark 128;
}
disk {
on-io-error detach;
no-disk-barrier;
no-disk-flushes;
no-md-flushes;
}
syncer {
al-extents 3389;
rate 110M;
}
on virtual1 {
device /dev/drbd0;
disk /dev/mapper/pve-drbd;
address 10.0.0.1:7788;
meta-disk internal;
}
on virtual2 {
device /dev/drbd0;
disk /dev/mapper/pve-drbd;
address 10.0.0.2:7788;
meta-disk internal;
}
}
Now, I want expand the drbd disk without shutdown the VMs that are running in the cluster.
I have seen that I can use two method:
1- add disks in the physical server, setup a new drdb device on both machines, create a new resource (for example r1) and add the new disk (lvm) with proxmox webgui. With this solution all work fine.
2- add disks in the physical server and expand the dev/pve/drbd volume. With this solution I have some problem.


If you consider that new disk is /dev/sdb and the relative partition /dev/sdb1, the procedure that I have used is this:
pvcreate /dev/sdb1 -> create a new physical disk
vgextend pve /dev/sdb1 -> extend VG pve
lvextend -L+100G /dev/pve/data -> extend LV /dev/pve/data
##Set a drbd node in secondary state
drdbadm secondary r0
##Run resize command in the other node (node in primary state)
drbdadm resize r0 -> Resize primary DRBD resource
resize2fs /dev/drbd0 -> Resize filesystem


The problem is that when I runnig resize2fs /dev/drbd0 command I obtain this error message and the size in the drbd disk not change:


resize2fs: Bad magic number in super-block while trying to open /dev/drbd0
Couldn't find valid filesystem superblock.
Or this error:
resize2fs: Device or resource busy while trying to open /dev/drbd0 Couldn't find valid filesystem superblock.
Can you give me some tips to resolve this problem?


I have seen that if I shutdown all my VMs and instead to use resize2fs command I use the pvresize /dev/drbd0 in one node, the size of the
drdb disk is expanded correctly but in this way I must poweroff all my VM.
There is other way to expand the size of the my drbd disk without shutdown the VM in the cluster?


Thanks you in advance.

Connect 2 bridges to the same network card

Hi,

I have a 2 proxmox servers, both with a network card (eth0) connected to a virtual rack (isolating the network trafic between these 2 servers).

I wanted to create 2 bridges (vmbr0 and vmbr1) for my VMs on the same network card (eth0 - connected to the virtual rack) so that I can use both :
- a network with a public range of IP adresses (connected to vmrb0)
- and a network with private range of IP adresses (connected to vmrb1)

Unfortunately, despite the different settings I have tried : vmbr0 uses eth0 (same MAC adress) and I can access the traffic on the virtual rack, but vmbr1 is associated to a different MAC adress and does not access the network trafic on the virtual lan.

Is my initial idea wrong and therefore cannot work, or is there a special way to achieve such a setting ?

Thanks for your help,
Hakim
