Re: [PVE-User] Proxmox 6 loses network every 24 hours

[Gerald Brandt]

Changing Proxmox from DHCP on vmbr0 to static stopped the issue.

Hi,

I have a Proxmox 6 server at SoYouStart https://www.soyoustart.com. 
I've been running a server there for years, running Proxmox 4. Instead 
of upgrading, I backed up all my VMs, did a fresh Proxmox 6 install, 
and restored my VMs. It works well, except for NFS, but that's another 
topic.



Every 24 hours, vmbr0 disappears. The SoYouStart staff can't ping the 
machine, assume it's gone down, and hard reboot the server. 24 hours 
after it's up, the cycle repeats. I'm not sure what is going on.


One weird thing, is that vmbr0 isn't configured in Proxmox, SoYouStart 
has it configured some other way. Could this be part of the problem? 
It looks like vmbr0 gets its IP via DHCP. (Yup, check in 
/etc/network/interfaces)

[PVE-User] Cannot start VM - timeout waiting on systemd

[Gerald Brandt]

I get a timeout waiting on systemd when I try to start a VM. Any ideas. 
It's not CPU load or memory.

I don't. I'll get something in place. htop showed good memory usage, 
disk space was fine. I noticed NFS dropped off for a bit, so looking 
into that. It was up when I checked out the system.

[PVE-User] Can't start VM

[Gerald Brandt]

Hi,

I have a small cluster of 4 servers. One server in the cluster seems to 
be having an issue. For the last two weeks, one or two of the VMs seem 
to psuedo lock up over the weekend. I can still VNC in and type in a 
login, but after typing the password, the system never responds. Also, 
all services on that VM (web, version control) are non-responsive. A 
reset from VM console doesn't work, I need to do a stop and start.



However, on start, I get this from the Proxmox server, and the VM never 
starts:


Feb 10 09:29:32 proxmox-2 pvedaemon[1142]: start VM 107: 
UPID:proxmox-2:0476:0311D642:5E4176DC:qmstart:107:root@pam:

UPID:proxmox-2:0476:0311D642:5E4176DC:qmstart:107:root@pam: timeout

I have to migrate all the VMs off the server and reboot the server. Any 
ideas?

[PVE-User] NFSv4.1 multipath available?

[Gerald Brandt]

Hi,

I'm mount my NFS server (images and backup) as vers=4.1. It works quite 
well. I currently use balance-rr across 2 GigE links to talk to my NFS 
server.


Is there a way to set up multipath with NFS instead?

It appears that the NFS storage target was unreachable during that time...



It affecting backups and VM speeds. Any idea what is causing this?


I would guess that the network link used for accessing the NFS target is
getting saturated. This sometimes can be caused by running backup jobs,
and/or other tasks like VMs demanding high i/o to that destination.

There are no errors in the Synology logs, and the storage stays mounted and

accessible.


You mean that it stays accessible after the backups are finished (or
failed) and after the i/o operations return to the normal levels ?
Do you recall if there was any of the above happening during that time ?



Any ideas what's going on?


I would set bandwidth limits either on the storage target or on the backup
jobs. See documentation for details on how to achieve this.
Even better, separate VMs from the backups if that's possible (i.e use
different storage/network links).

G.

Thanks for the reply. Although it does happen during backups, causing 
serious issues that require Proxmox server restart, it also happens 
during the day. I don't see any saturation issues during the day, but 
I'll start monitoring that.


So you're saying to set network bandwidth limits on the storage network 
(I do keep a separate network for storage). I guess upgrading the 
synology's with something that has 10GE would help as well.


Thanks,

Gerald

In my experience, XFS has been more reliable, and robust. But anyway,
99.9% of the time, FS corruption is caused by one of the underlying layers

- All they have the same date / time (It is one of the causes It could 
lose the communication)


- The environment is ident (No new switch, no new server)


And why all these nodes lost the communication at the same time ? If 
they are 10 at least 5 have to be with problems to lost the quorum and 
then the connection. Is it true?


I think it is something related to this proxmox version.

What to do ?





That happened to me a few versions back on a 3 node cluster. I had to 
switch heartbeat from multicast to unicast to keep things stable. There 
were no changes in any of my equipment when this happened.

I now it works, it's a switch problem - maybe it is broken, maybe it

I have seen this two times:
- One switch was broken and lost packages -> new switch
- Other switch was core 3Com switch; we seemed unable to configure it 
not to drop our cluster communication packets, so just bought a dumb 
enought HP 1810-24g switch just for the proxmox nodes and problem solved.

Hi,

I've just been given the task of maintaning an existing "cluster"
of Proxmox 4. I'm putting quotes around the word because currently,
it doesn't work. Each nodes seems to have been somehow added to a
cluster and can see the other nodes, and the sumary tab does work
for each node, but they all show offline except the one I log on.

Since they were all different versions, I just tired updating them
to the latest 4.4, but not better. Then I took a look and realised
that they are all missing the /etc/pve/corosync.conf file.
The command "pvecm status" on some of them just returns that the
file is missing, and on some others says that then does show a
status of a cluster where they are the only one connected (which
a "Activity blocked" since they don't have quorum).

Any idea what happened ? How to fix it ?


Looks like they can't find each other. Make sure each server has 
/etc/hosts entries for all the other servers.

My guess is their DNS server provided the names, and when the cluster

fell apart. However, that doesn't make sense either, since the DNS 
server needed to be running before the cluster and quorum worked, and 
without quorum, there was no DNS server.

Just found out something new. The DNS server was running on an old 
XenServer system, and was recently turned off. So, Proxmox could've been 
getting node names<-->IP addresses via DNS, and starting up OK.

I hope it is at least 2003 R2

Mine isn't, and it's a PITA. I hate IT people that don't upgrade when 
needed.

any suggestion to migrate physical windows 2003 server to Proxmox ? 


I won't do that, as windows 2003 server is no more supported by 
Microsoft, since at least July 2015.


I would create a new VM using windows 2008 R2 or 2012/2012 R2, join it 
to the AD domain, then promote it as AD controller, then demote the 
old server.


My two cents.

Alain



Can't do that unless you're running 2003R2. Straight 2003 can't be 
joined by much.

I use Synology (replicated) for my storage. Migration between 3 servers 
(2 AMD, 1 Intel) works fine. I did change proxmox to use NFSv4 instead 
of NFSv3.

Re: [PVE-User] about IO Delay using openvz and zimbra

[Gerald Brandt]

Hi,

Your fsyncs per second are brutal, and Proxmox needs high fsyncs. I 
would start there.

Hello friends

I am SysAdmin at the Agrarian University of Havana, Cuba.

  


I have installed Proxmox v3.4 here a cluster of seven nodes and for some
days I am having problems with a node in the cluster which only has a
Container with Zimbra 8.

The problem is I'm having a lot of I / O Delay and that server is very slow
to the point that sometimes the service is down.

The server is PowerEdge T320 Dell with Intel Xeon E5-2420 12gram with 12
cores and 1GB of disk 7200RPM 2xHDD are configured as RAID1.

I have virtualizing the zimbra 8 using a template of 12.04, has 8 cores, 8G
RAM, 500GHD the storage of container is local storage.

Then I put the output to see the IO when you are not running the VM. Look at
the BUFFERED READS that are marked are very bad. And those moments have seen
IO Delay up to 50%.

(yes, i should cleanup old kernel versions...)

steps i took sofar:
* migrated all vm's of one node
* upgraded this node
* rebooted it
* tried to migrate vms back to this host to upgrade another one

since there was a thread on the mailling list about migration
problems that where fixed with newer qemu-server/pve-qemu-kvm
version, i then upgraded the other two nodes (disabeling HA first).

i still cannot online migrate, even a vm that has been booted on the
fully upgraded node.

unfortunatly the error message i get is not really informative:
ERROR: online migration failure - aborting

am i running into some known problem here or is this a new issue?

thx

regards,
albert

ps: rebooting the remaining nodes without migrating the VMs off them
would be really inconvinient...

Re: [PVE-User] NFSv4 support for NFS storage?

[Gerald Brandt]

On 2016-05-06 08:41 AM, Frank Thommen wrote:

Hi,

new fileservers in our department are configured to require NFSv4 and 
do not support NFSv3 any more.  That worked fine for PVE 3.x by 
patching the "values.options" assignment in 
/usr/share/pve-manager/ext?/pvemanagerlib.js.


When applying the same patch to PVE 4.x, the storage is mounted 
correctly and also shown in the summary, but the status is inactive 
and `pvesm list ` returns "mount error: mount.nfs: 
/mnt/pve/ is busy or already mounted". In the content tab, 
the error "mount error: mount.nfs: /mnt/pve/ is busy or 
already mounted (500)" is shown.


Is there any other patch which has to be applied to make NFSv4 working 
with PVE 4.x and is there already a timeframe, when NFSv4 will be 
supported out of the box?


We are currently running "pve-manager/4.1-33/de386c1a (running kernel: 
4.2.6-1-pve)".


Cheers
Frank


I go into /etc/pve/storage.conf and add or change vers=4

I presume the VMID is "111"?

try
systemctl stop 111.scope

then

qm start 111



I ended up hard resetting the server with

echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger

This happens almost weekly, so I'll try your suggestion next time and 
report back.

Re: [PVE-User] Proxmox not responsive

[Gerald Brandt]

Hi,

I've been running NFS storage on Proxmox 3.x for quite some time. 
Proxmox 4 a bit more recently. I do force NFSv4 for all of my NFS 
mounts, except the one that hung. I may have to change that to v4 as well.


Luckily, command line worked for me still, so I migrated my VM's (except 
the hung backup one) to another server and reboot. Just about to do the 
same with the second non-responsive server.


I tried GlusterFS back in my XenServer days, and had issues with it's 
NFS server. Now I run Synology storage, and GlusterFS is not an option.

I also have a process taking 100% of a CPU:

Is the storage shared? if so, you could manually move the vm .conf files

It is shared. Moving the conf files should be significantly faster than 
backup/restore.

[PVE-User] Windows VM's consistently hang on snapshot backup

[Gerald Brandt]

Hi,

I'm running the latest 3.4, and my Windows VM's hang on snapshoy 
backups.  Not every time, but 9 out of 10.


I'm running qemu disks on an NFS server.

Has anyone seen this before?  I already tried change the cpu from kvm64 
to qemu64, but no changes.

Re: [PVE-User] NAS4Free and ZFS

If I would have thought things through a bit better, I would just have 
built a couple of NAS4Free boxes instead of using Synology.

I use it to create user directories with fixed quotas and share them 
over CIFs.  Each user has there own dataset and the dataset is shared.


The Proxmox VM is using direct sync cache mode on the NAS3Free disk.  
I do backup and snapshot daily, so data loss will be minimized if 
anything bad happens.  I also turned off any scrubs on the pool.  I 
used to do them nightly, but read somewhere it wasn't recommended in a 
virtual environment.


The NAS4Free disk is on an NFS file server with its own RAID6 and DRBD 
setup (Synology).


It's been really stable, and I'm considering putting some more 
critical data on it.

Hi Gerald
A problem here might be that different storages have different
interpretation of what is considered to be online.

IIRC for example with NFS, when the nfs server disappears in the
network, the mount is still considered to be valid by the kernel, and
the next file system calls will hang, waiting indefinitely for the
server to be online again.

So at least for NFS, I don't see an easy way to detect a storage as
being offline.

Hi,

I have never backuped any VM.
I consider every VM as a server, so I backup the data inside (rsync

If someone can tell me what is the advantage to backup the VM, maybe I 
will change my mind :-)



I backup the data in the VM (using BackupPC) daily.  I vzdump the VM's 
weekly for disaster recovery purposes.  The snapshots and friday backups 
go offsite.  If the building burns down, I can build a new Proxmox 
system, and restore from vzdump, losing, at most, a week of work.  No 
fiddling to rebuild servers and restore from backups, just a restore of 
the image.


I verify the offsite on a semi-monthly basis.

[PVE-User] Internet facing Proxmox

[Gerald Brandt]

Hi,

I've been asked to set up a Proxmox server on the Internet.  Has anybody 
done so, and how secure is the web interface on port 8006?


I was considering running a VPN on Proxmox, and not allowing port 8006 
access unless you were connected to the VPN.  That creates issues if the 
VPN server goes down.


Also, with the new built in firewall, how easy is it to run all VPN's on 
a private address space and port forward as needed?

I tried Gluster, both native and it's NFS implementation.  The NFS 
worked great, until it didn't.  It began to fail under load.  The 
Gluster native worked fine, but halved my IO.  I was doing replicate 
gluster, which sends data to all (in my case 2) bricks over the same 
link, essentially reducing your speed.  2 bricks in replicate, half the 
speed.  3 bricks, 1/3 of the speed.


Gluster NFS replicates it's data between servers, not between client and 
server, and can be off-loaded to another network link.


I settled on standard kernel NFS with DRBD to replicate the data.  I 
changed the Proxmox config files to use NFSv4, and I am super happy.

[PVE-User] Add server to non HA cluster

[Gerald Brandt]

Hi,

I'm adding a new node to my cluster.  Just to make sure I have this right, I 
execute the 'pvecm add IP' on the new node, and the IP is the address of 
the existing cluster.

Correct?  I don't want to get it wrong by mistake, and take out my cluster.

Re: [PVE-User] openiscsi with Proxmox

[Gerald Brandt]

Hi,

I’ve used Ubuntu + DRBD + IET iSCSI in production for the last 4 years for a 
client of mine.  They are running XenServer instead of Proxmox.  I’ve just 
converted another client to Proxmox from XenServer, and am testing an Ubuntu + 
DRBD + NFS system now.  This client has used XenServers snapshots on iSCSI for 
a long time, and want the same functionality with Proxmox, which is only 
available with qcow2.

 is there anyone have used openiscsi with Proxmox in production? 
 for example. openfiler or manual openiscsi?
 what is your recommendation for the backend SAN/NAS box other then freeBSD or 
 FreeNAS as both lagging DRBD and i want to setup an HA with DRBD. 
 any suggestion would be highly appreciated.
 
 Thanks

 Thanks Fabio for your kind input. 
 i will keep on learning on this application, from learning perspective nappit

 do after that because the problem can only be extracted from SSH. 
 
 
 
 @Gerald Brandt
 
 would you please share some details about your ubuntu + DRBD + IET box
 
 Can you please share the hardware specs in details (RAID CARD, Number of 
 Drives, Capacity, RAM etc.)?
 
 as you know writes are slow on DRBD how come you manage that?
 
 what was the Ethernet throughput 1GB or less?
 
 how it performed under heavy load?
 
 Thanks,

Hi,

I use Intel Server motherboards, software RAID-6.  RAM is 4 GB.  Reads and 
writes easily saturate the 1GB link, peaking out at 118 MB/s.  The DRBD sync 
line is a direct connect cable.  I can get the DRBD and IET config files if you 
like, but they are pretty generic.

 Are you using Sata1,Sata2 or Sata3 or SAS?
 
 i will more then happy to read these configs. i only used heartbeat once. if 
 you share the config it will help me alot recalling the old learning. and i 
 never used IET so it will be best for me to learn some thing new. 
 
 I am also interested to see the connectivity diagram (if Possible for you) 
 like how you have connected both nodes and fine tune the the setup by using 
 Jumbo frames, reducing latency etc. because i also need constant 1GB Ethernet 
 output.
 
 
 Thanks,
 
 

Nothing special on my end at all.  I use uCARP for failover of the IP at one 
client and heartbeat at the other.  No jumbo frames either, since when I set up 
XenServer it wasn’t supported.  I kept my disk traffic on a separate 
network/switch from the user traffic.

I’m testing bonded (balance-rr) links now with my NFS test setup.

Re: [PVE-User] Question about backup...

[Gerald Brandt]

When you create the disk, there's a 'no backup' option.  You can double click 
on the disk and set it there as well.

[PVE-User] disk move from local to LVM over iSCSI Failed

[Gerald Brandt]

Hi,

Is this a good place to post questions, or is the forum better?

I just created an LVM over iSCSI share for testing.  I then picked a running 
test VM, and moved its disk from local:100/vm-disk-1.qcow2,format=qcow2,sie=8GB 
to the iSCSI.  

The copy went through, completeing to 100%, I've attached the log.  The copy 
failed on 'remove ioctl'.  Now I have an active working drive on local, and a 
duplicate drive on the iSCSI, and I can't remove the iSCSI drive.

Any help appreciated.

[PVE-User] Moving from XenServer to Proxmox... slowly

[Gerald Brandt]

Hi,

We've pretty much made the decision to move from Citrix XenServer to KVM 
(Proxmox) for our Virtual solution.  Unfortunately, I don't have all the 
computers available to me at the start, since migration will use the existing 
XenServer computers.

To start, I'll have two servers, using a single iSCSI, in an HA cluster.  Once 
they are running and some of the virtual machines are migrated, I can add a 
third server.  Finally, I can add the fourth server.

Is there anything I need to look out for when creating the 2 server HA cluster 
and then converting it to a 3 and 4 node cluster?
Has anyone done this, and created a HOWTO I can follow?

Thanks,
Gerald

ps: Been using Citrix XenServer since Jan 2009.  We've had enough issues with 
VM disk corruption to haunt me for year (using LVMoveriSCSI).  It's a bloody 
house of cards.

Re: [PVE-User] Moving from XenServer to Proxmox... slowly

[Gerald Brandt]

Hi,

I'd considered that, but I'm having trouble finding a system that supports 
VT-d/VT-x.

Any hiccups converting Xen to KVM?  I imagine the Windows boxes will move 
easily enough, just using clonezilla or similar.  The rest of my servers are 
Ubuntu based, and PVM's so I'll need to add a kernel, so I'm looking at 
http://www.blog.turmair.de/2010/12/xen-to-kvm-or-physical-vmware-migration/

Any performance issues?

 Hi,
 
 we did pretty much the same thing over the past weeks, ie. changing
 fom
 XEN to KVM (Proxmox) reusing the hardware already in place and
 production. But we didn't went down the 2-Node cluster road, what we
 did
 instead was, that we used an old server machine as a third node, just
 for the sake of quorum and not having to deal with all the problems,
 that may occur on a 2-Node cluster. No guests on that machine and as
 soon as the 3rd production machine was free, we added it to the
 cluster
 and removed the old one.
 I guess performance is not an issue for that 3rd machine, as long as
 it
 has no guests.
 
 Hope that helps a little,

  Any performance issues?
 In which regard?

Noticable slowdowns/or speed ups on disk IO or memory, etc?

  Hi,
 
  we did pretty much the same thing over the past weeks, ie.
  changing
  fom
  XEN to KVM (Proxmox) reusing the hardware already in place and
  production. But we didn't went down the 2-Node cluster road, what
  we
  did
  instead was, that we used an old server machine as a third node,
  just
  for the sake of quorum and not having to deal with all the
  problems,
  that may occur on a 2-Node cluster. No guests on that machine and
  as
  soon as the 3rd production machine was free, we added it to the
  cluster
  and removed the old one.
  I guess performance is not an issue for that 3rd machine, as long
  as
  it
  has no guests.
 
  Hope that helps a little,
  best regards,
  Kurt

  Hi,
 
  We've pretty much made the decision to move from Citrix XenServer
  to KVM (Proxmox) for our Virtual solution.  Unfortunately, I
  don't
  have all the computers available to me at the start, since
  migration will use the existing XenServer computers.
 
  To start, I'll have two servers, using a single iSCSI, in an HA
  cluster.  Once they are running and some of the virtual machines
  are migrated, I can add a third server.  Finally, I can add the
  fourth server.
 
  Is there anything I need to look out for when creating the 2
  server
  HA cluster and then converting it to a 3 and 4 node cluster?
  Has anyone done this, and created a HOWTO I can follow?
 
  Thanks,
  Gerald
 
  ps: Been using Citrix XenServer since Jan 2009.  We've had enough
  issues with VM disk corruption to haunt me for year (using
  LVMoveriSCSI).  It's a bloody house of cards.

Re: [PVE-User] cluster with no HA

[Gerald Brandt]

Hi Lex,

The cluster would only be two nodes for a day, two days at the most.  The third 
node would come in really quick (install and config time), and then there would 
be three nodes.

Hi, no problem with that, except possible problems with quorum.

 Can I create a Proxmox cluster, starting with 2 nodes, then increasing to
 4 nodes over a few days, with no HA ability, and then add HA/fencing

[PVE-User] Named backups

[Gerald Brandt]

Hi,

Proxmox currently names backups based on the VM id number.  Would it be 
possible, and are there any plans for, using the VM's name instead?

Thanks Marco,  don't know why I didn't find that.

[PVE-User] Backups suddenly slow

[Gerald Brandt]

Hi,

I made two changes to my server since the last backup:

1. switched from 2.1 to 2.2
2. converted vmdk storage to qcow2 (for snapshots)

Here's a sample from last weeks backup:

And here is this weeks:

Is anyone else noticing a change?  Will going back to vmdk help me?

Gerald

ps: are there plans to create full backups using the qcow2 snapshots?

[PVE-User] Proxmox 2.1 'internal' network

[Gerald Brandt]

Hi,

I'm moving from Citrix XenServer to Proxmox, so my question may be simple ones.

In XenServer, I can create an internal network.  The XenServer itself is on a 
physical network card, while all the VM's are on the internal network.  All the 
VM's go through a firewall between the network card (routable IP) and the 
internal network (non routable IP 192.168.x.x).

Is there a way to setup and maintain is similar network layout in Proxmox 2.1?
