BIND dns server rquired

February 21, 2013, 8:31 am

Can anyone confirm if the BIND server that comes preinstalled and running with PVE 2 (on OVH servers at least) can be safely disabled and removed.
I use to run a small DNSMASQ instance on the host merely to act as a DNS cache and central point for all VMs on that host and BIND just seems to be too much for that.
Thanks.

pvectl list: missing vm

Hi all,

Doing a pvectl list displays a list with a missing vm?
pvectl list
Use of uninitialized value in printf at /usr/bin/pvectl line 46.
VMID NAME STATUS MEM(MB) DISK(GB)
101 repo running 512 50.00

As the above shows the command also displays an error.

Proxmox clustered and SAN problems

Hi All,

Bit of a long shot here I have inherited a 2 node cluster connected to a SAN all fairly new kit, the problem I have is the VM's are all running i am able to start stop etc.

However when i try to migrate from one node to another I get the following

ERROR: migration aborted (duration 00:02:05): Failed to sync data - mount error: mount.nfs: Connection timed out
TASK ERROR: migration aborted

Now if i go into storage view the 2 nodes are visible with red marks in them.

Also if i try to create a new VM I have no storage pools to select from, I cant even select an iso from local storage.

Any help would be great.

Regards

Open-VZ, Samba and additional HDD(s)...

February 21, 2013, 1:27 pm
$

After reading a lot, here is my first post...

The system has the following hardware:
HP ML350 with 2 Xeons / 8GB of RAM
6 SCSi-HDDs on a SmartArray-Controller
2 of them build a Raid 1 ==> /dev/cciss/c0d0
4 of them build a Raid 5 ==> /dev/cciss/c0d1
ProxMox is installed with default values on c0d0 (lvm etc.)
The first goal is to have a smb-server. Since i'm quite familar with samba i downloaded the turnkey-domain-controller template and let it run in an open-vz container.
Until here everything works fine, samba is up and accessible via the web-frontend. The PDC is visible by clients, shares can be created, etc...
Problem now is, that i want to share files which are on an existing NTFS-partition "/dev/cciss/c0d1p1" via SaMBa, but the partition doesn't show up, neither in proxmox-frontend nor in the container-frontend.

Until now I tried the following:
- logged in via ssh on the host system
- installed NTFS-Support with "apt-get install ntfs-3g"
- mounted the partition testwise manually to a directory "/storage". Worked fine, files are visible an accessible in the console, but nothing happened or showed in the samba container
- made the according entries in fstab an rebooted the machine: same result. Filesystem is mounted correctly but nothing "shareable" appears in host- or guest-frontend.
Hmmm... :confused:
Probably i have some some lacks in my understanding of the storage concept - could maybe someone light me the way? Thanks ...

Two Node cluster, each node only sees itself "online" in GUI

Everything appears to be functioning properly other than each node only sees itself as online (green). I can access the other node in the GUI but it does not display the VM names, only IDs, and its icon appears as red.

I have updated to the newest Proxmox release and rebooted the nodes several times. The nodes have 2x bonded 1gbps crossover for node communication and drbd. Multicast seem to be working fine tested with asmping.

This server then hangs and will not go any further. Any ideas on where to start? I am pretty new to proxmox and didn't want to fool with it too much until I got some ideas from you guys. Thanks in advance.

how to switch vm console to/from read only mode?

hi,
is there any way to put the browser-vnc console in read only mode?
sometime i need to be able to look what a user is doing without interfering with its activity (mouse pointer)

before you ask, no i'm not spying users, its an external tech support for a commercial app that often needs to work an a windows server (btw via the "supremo" remote control app). i just wish to be able to check what he's doing, in case something goes wrong. sometimes he asks me to act locally (because it's faster) so i need to be able to switch back to interactive mode, too. i think it's possible with the regular vnc client too.

any ideas? is this regulated by a "monitor" option or else?

Thanks, Marco

Omnios: zfs and iscsi

Hi all,

FYI. Omnios (latest stable) seems to have fixed the zfs and iscsi problems found in freenas, nas4free and openindiana. Even with ZIL in sync mode I have not been able to provoke any iscsi errors yet. And since latest napp-it has official support for omnios (the developer is actively migrating all his current openindiana systems to omnios) we seem to have found a winner for NAS/SAN in the production server room:p

Proxmox 1.9 -> Proxmox 2.2/2.3 test issues

February 23, 2013, 1:56 am
$
0

Hi,

I've migrated over 40 of our VM's to Proxmox 2.2 and/or Proxmox 2.3 test and I have two that I can't seem to get to work.

The first is an OLD BSD/OS machine that worked fine in Proxmox 1.9 (and also worked fine in Proxmox 2.1), now when I try boot it, it gets partway through the boot (up to the point where it changes the root device to wd0a) and starts complaining about "wd0: lost interrupt". FYI - even on Proxmox 1.9, this VM only runs when I set the CPU to an old CPU (currently using 486).

My second problem machine is a 32 bit Solaris 10 machine. Again this works fine in Proxmox 1.9 (using "args: -no-kvm"), but in Proxmox 2.2/2.3test, I get "disk read error, sector xxxxxxxxx" where xxxxxxxxx is usually a large value (e.g. 31780350) followed by "Short read. 0xffffffff chars read".

I'm putting these both in the same thread because I suspect they may have the same problem. Is there something about either the ide controller or disks in general that changed with 2.2? I never tried the Solaris VM on my 2.1 machines before upgrading, so I don't know if it would have worked with 2.1 like the BSD/OS machine.

Thanks,
Jeff

Hi all,

i am planning a new proxmox infrastructure which requires high I/O performance and was thinking about including PCIe SSD disks. Due to their high costs, we cannot buy them just for testing and finding they do not behave well under Debian/Proxmox.

I would be delighted if any of could tell me any experience they have had in such an environment and perhaps give some recommendations on which hardware models work flawlessly under Proxmox.

what are the maximum virtual CPU's per Host?

to the VM system:
what are the maximum virtual CPU's per VM?
what is the maximum physical memory per VM?
how many active VM's per Host can exist?

to the cluster:
how many nodes can be in a cluster?
how many VM's can be in a cluster?

Hi,

i want to passthrough a SATA-Controller to a VM, all works well so far.
But is it possible, to unbind the PCI/PCIe Device already on boot, so that the host can't see the controller at any time (as it is in ESXi)?

MTU for Dummies ?

Is there by chance a "how to set mtu for dummies" guide?
I did some searching - found some perl code - in the forums - some referenced back to 1.x etc...
Sadly searching the forums since 2.x is out has been a bit more difficult

that being said here is what I need to figure out.

We have a cluster with 8 systems in it.
We want to have that cluster use our SAN.
Our SAN is set to an MTU of 9000 on its own ip range (not vlan just ip range)

What I would like to do in each system is setup so the vmbr0 operates at its normal 1500 MTU
and each system to have the eth1 network port to use the MTU of 9000

Truth to be told some systems have more than 1 card so doing some bonding might help - but for now just setting these up with the mtu of 9000 and being able to force the traffic for the SAN to go over eth1 vs vmbr0 is really what we need.

So - any ideas

If the SAN network is 192.168.13.1/24 where .254 is the san ?
:confused:
