Hi,

I have a problem with an identical nfs mount in different VEs

for example, I have inside some VEs :

$ df /mnt/data
10.0.0.1:/nfs/data 134148096 43458560 90689536 33% /mnt/data

if I perform a reboot on one VE, on all others VEs where this partition is mounted, I got :

$ df /mnt/data
10.0.0.1:/nfs/data - - - - /mnt/data

so the partition is still mount but impossible to do an access on.

at the same time I got this in kernel log on the host :

[258012.479557] unregister_vlan_device: ERROR: Tried to remove a non-vlan device with VLAN code, name: eth1.35 priv_flags: 0
[258012.646468] unregister_vlan_device: ERROR: Tried to remove a non-vlan device with VLAN code, name: eth1.32 priv_flags: 0
[258013.466439] nfs: RPC call returned error 101
[258013.711497] nfs: RPC call returned error 101
[258013.715907] nfs: RPC call returned error 101

As soon as I removed all references of that mount point in all VEs. I can remount it, it's working.

VE 201 :

no idea ?

If you need more information, I can compile new kernel with debug option but I don't know which one can be usefull

or I'm able to do lot's of test

attach : config-2.6.18-028stab053

Hello,

Sorry for delay.


1.
Could you possibly specify how did you exactly configure network inside VE and on HN? You can show us the exact commands if it is convenient for you.

2.
How do you mount content via NFS?
Something like that? http://wiki.openvz.org/NFS

Thank You!

see in attachement for all details about networks and nfs configuration

I can do all tests needed

Thanks for your help

Hello,

I've been trying to reproduce this issue but I haven't been able to do that.
This sounds like a bug.
Is that issue reproducible on any OS template? Please try to do the same with VE based on the non ubuntu template for example with centos or fedora template.

Is that HN is a production node? Could we get an access to it if we won't be able to reproduce this behavior?

P.S.

Could you please clarify what does it mean?

if I perform a reboot on one VE,

after a couple of day of investigation, I have more information about the problem.

In my test, I have 3 VE, one centos5 i386, one centos5 x86_64, one ubuntu Dapper 6.06

in all VE I have an ip set on eth1.35 and all have the same nfs directory mounted.

If I run a ifdown eth1.35 on centos, no problem but I if run ifdown eth1.35 on the ubuntu, nfs mount point borked... until I run an ifup eth1.35.

So it seem that the script inside the VE on ubuntu is doing something that not supposed to do and change something inside vlan configuration for others VE.

in attachment the result of

strace ifdown eth1.35 > /tmp/ifdown.eth1.35.trace 2>&1

Some additional informations uselfull I guess :

for each VE, I have 3 mount points over the same vlan 35; but each are mounted with different nfs server IP .

IP1:/mnt/data1
IP2:/mnt/data2
IP3:/mnt/data3

IP1 IP2 IP3 are on the same vlan and all of them are set on the same nfs server for now (can be move separately, each IP is associate to a drbd device)

here come the strange part of this bug :
only one mount point is affected by this bug, the 2 others are working perfectly in others VEs after set down eth1.35 inside the VE running ubuntu.

edit: the vlan35 is also the network used for root over nfs for the HN, and where are hosted /vz/private for VE.

rootfs for HN and VE are on a separate nfs server dedicated to rootfs and not on the same server used for /mnt/data1, /mnt/data2 and /mnt/data3

the HN is completely diskless

but, it's still complicated to fully qualified this bug...

Hi,

I've suspected that something is not quite clear with ubuntu "ifdown*" utilities.
But the fact is that in redhat based OS ifdown is a simple script so it's easy to investigate it:
it calls appropriate script in /etc/sysconfig/network-scripts/.
And the only thing I've found there is:
if [ -n "$VLAN" -a -x /sbin/vconfig ]; then
    # 802.1q VLAN
    if echo ${DEVICE} | LANG=C egrep -v '(:)' | LANG=C egrep -q '(eth|bond)[0-9][0-9]*\.[0-9][0-9]?[0-9]?[0-9]?' \
        || echo ${DEVICE} | LANG=C egrep -q 'vlan[0-9][0-9]?[0-9]?[0-9]?' ; then
        [ -f /proc/net/vlan/${DEVICE} ] && {
            /sbin/vconfig rem ${DEVICE}
        }
    fi
fi


So,

1. If it's possible we can investigate src files of appropriate utilities in ubuntu OS.
2.

strace ifdown eth1.35 > /tmp/ifdown.eth1.35.trace 2>&1



ifdown can generate another process so could you possible try to it in the following way:

strace -fF -o out.txt ifdown eth1.35


Thank You!

Yep, that's true.

bridge : located in /etc/network/if-post-down.d/bridge
vlan : located : /etc/network/if-post-down.d/vlan
ifdown-venet : located : /etc/sysconfig/network-scripts/ifdown-venet

in /etc/sysconfig/network-scripts/ there are 2 others scripts : ifcfg-venet0 and ifup-venet and in /etc/network/if-down.d/ there is only postfix script but there are not used in our case i guess.

I've try ifdown without those script (move them to /tmp), but nothing change

see out.txt *with* script in /etc/network/if-post-down.d/ and /etc/sysconfig/network-scripts/

see out2.txt *without* script in /etc/network/if-post-down.d/ and /etc/sysconfig/network-scripts/

Thank you for your help

Hi,

1. But we've get rid of the message "unregister_vlan_device: ERROR: Tried to remove a non-vlan device with VLAN code, name: eth1.35 priv_flags: 0", haven't we?

out.txt
Quote:


execve("/sbin/vconfig", ["vconfig", "rem", "eth1.35"], [/* 11 vars */]) = 0



out2.txt
Quote:


execve("/sbin/ifconfig", ["ifconfig", "eth1.35", "inet", "0"], [/* 15 vars */]) = 0


So, in the first case we call vconfig to remove non-vlan device with a VLAN code; in the second case we call ifconfig to put down the interface.

2. When you run "ifconfig eth1.35 down" inside the ubuntu VPS other VPSes loose an access to nfs share. Is that true? And when you run "ifconfig eth1.32 down"?

3. Anything in logs or in dmesg?

P.S. I don't expect this help but could you possible rename your eth1.35 interface inside VE to eth1?

in fact, inside a VE eth1.35 is not eth1 with vlan 35 tag, it is viewed as a physical interface for the OS, so /proc/net/vlan/config is empty, if I understand well.

Quote:

ubuntu script ckeck if the interface is associate to a vlan by the name : ethX.Y where Y is the number of the vlan

but in this case, the number after the interface does not refer to the vlan conf for the VE but refere to the bridge associate to the vlan in the HN.

I'm loosing only one nfs share out of the 3 used, I can ping the nfs server, I can ssh the nfs server, I can read or write on the 2 others nfs share, but one specifically die...

that's the really strange point...

Quote:

3. Anything in logs or in dmesg?


I got this in the dmesg on the HN

[258012.479557] unregister_vlan_device: ERROR: Tried to remove a non-vlan device with VLAN code, name: eth1.35 priv_flags: 0
[258012.646468] unregister_vlan_device: ERROR: Tried to remove a non-vlan device with VLAN code, name: eth1.32 priv_flags: 0

I can't due to the vlan configuration on switchs, but I've add just eth1 to the VE which not exist before (only eth1.35 and eth1.32), but nothing has changed.

all tests are done on a test server but over a network setup where is the production

so, I can really use vlan inside VE for now.


Yoann, still investigating

Hi,

I haven't understood you clearly:
Quote:

Yes, I think in the same way. According to your configuration.

Quote:


ubuntu script ckeck if the interface is associate to a vlan by the name : ethX.Y where Y is the number of the vlan

but in this case, the number after the interface does not refer to the vlan conf for the VE but refere to the bridge associate to the vlan in the HN.



So, I think we are talking about vlan script. Yes, I agree with you. It checks some conditions and then calls "vconfig" utility. I haven't looked at "vconfig" sources. May be it does another checks, I don't know but I have a question:
Have you got this message
Quote:


unregister_vlan_device: ERROR: Tried to remove a non-vlan device with VLAN code, name: eth1.35 priv_flags: 0


in the both cases (before and after you move /etc/network/if-post-down.d/ scripts)

You've mentioned that "ifconfig eth1.35 down" reproduces the issue. Could you possibly say does "ifconfig eth1.32" reproduce the issue?

Quote:


I can't due to the vlan configuration on switchs


I'm not clearly understand why can't you use "--netif_add eth1" instead of "--netif_add eth1.35"

P.S. I'll ask another people. I hope somebody could help us with this problem.

nop, I can't reproduce the issue with ifconfig eth1.32 down.

Ok, I understand. if I change eth1.35 by eth1, I can't reproduce the issue.

so I've juste remove the reference of the vlan in the name of the interface inside the VE, but nothing has been changed on HN side. eth1 is still associated to veth204.35, and on the HN, veth204.35 and eth1.35 are in the bridge brvlan35.

Hi,

I asked about your problem and the answer was the following:

1. Disable
CONFIG_NFS_V4,
CONFIG_NFSD
CONFIG_NFSD_V2_ACL
CONFIG_NFSD_V3
CONFIG_NFSD_V3_ACL
CONFIG_NFSD_V4
CONFIG_NFSD_TCP

and recompile the kernel, please?

2. Am I right that your NFS servers are running on the external node?

Hello,

1. Please show how do you exactly create eth* interfaces per VE. (the exact command - "vzctl set --netif_add ...")

2. And what is the order of interfaces you add to the bridge?
(for example: the first is eth1.35@eth1, then veth101.35, veth102.35 etc) And which of them cause the problem? I mean if the problem VE was the first to add?

3. Let's assume you've started several VEs and mounted NFS partition inside each of them. Please show "ip a l", "ip r l", "brctl show" from HN at that moment.
Then you can break this configuration via "ifconfig eth1.35 down" from inside the problem VE. Please, do it. And then show the previous commands from HN.

4. Let's assume you've broken the configuration. Do other VEs keep a network connectivity?

each VE is started one by one, interface are mounted in the ordre the are appear in the NETIF parameter in the conf file.

the if which create problems is the second one.

ubuntu script try to remove vlan35 for kernel,



So, does the command "ifconfig eth1.35 down" cause the message "unregister_vlan_device: ERROR: Tried to remove a non-vlan device with VLAN code, name: eth1.35 priv_flags: 0" or this message doesn't appear.

You have shown strace output of that command
http://forum.openvz.org/index.php?t=msg&&th=5949& ;goto=29539#msg_29932
I haven't been able to find anything related to VLAN.

What's the difference between strace "ifconfig eth1.35 down" and "ifconfig eth1 down" (after eth1.35 rename to eth1)? Why the second case doesn't break the system? Where is the difference in strace output?
I think this sort of investigation could help us. It's the good for us to understand the difference between the "good" and the "bad" cases.

ifdown, ifconfig and ip l set down reproduce this issue, but "unregister_vlan_device: ERROR: ..." appear only with ifdown

"/etc/init.d/networking stop" uses ifdown

so maybe it's not vlan related, and I'm working on the wrong way.

If I had the response...

there are no big diff between the 2 straces... ifconfig down does not break directly nfs export I guess, but by shutdown the interface (whatever the way to set down), something is broken in kernel land. If not, I can't see how an action inside a VE can affect another VE.
