| [ SOLVED ] Pb with multiple identical nfs mount dir in different VEs [message #29539] |

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 :

Hello,
Sorry for delay.
|
that's ok

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
|
see in attachement for all details about networks and nfs configuration
I can do all tests needed
Thanks for your help

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:
|
Yep, that's true.
| Quote: |
1. If it's possible we can investigate src files of appropriate utilities in ubuntu OS.
|
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
| Quote: |
2. ifdown can generate another process so could you possible try to it in the following way:
strace -fF -o out.txt ifdown eth1.35
|
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.

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...

I got this in the dmesg on the HN

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:

|
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'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.

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?
|
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.
| maratrus wrote on Mon, 26 May 2008 15:45 |
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.

| maratrus wrote on Mon, 26 May 2008 19:17 |
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?
|
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.
| maratrus wrote on Mon, 26 May 2008 19:17 |
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.
