Mine did run for 7hours! then the dude told me that is was down, then 2mins later it was up again.
5mins after it came up again, it went down for about 5mins and came up.
And has now been running for 1½ hours with no downtime.

2 Metarouters, just pinging to the host, stable since yesterday 15:00 UTC.
Each Metarouter doesn't show a single loss, max ping rtt 13-14ms.

Re: RB450G + openwrt Metarouter strange problem

Wed Sep 28, 2011 11:34 am

Conclusion by now: As both barkas and QpoX both have crashes regardless the switch switch-all-ports setting, I think we can rule that out.
Significant difference between my setup and barkas setup is, that my Metarouter does nothing more than just pinging over one interface, and barkas does full MPLS tests.
Janis maybe you could do some MPLS tests between Metarouter and host or some load tests using ipsec? Anything that touches ethernet/ip stacks and/or produces some load...

Re: RB450G + openwrt Metarouter strange problem

Wed Sep 28, 2011 2:19 pm

i have had router with metarouter freeze up without MPLS. I have one suspect that i am testing out, it crashed once without debug MetaROUTER, now router sits at devs with debug version of MetaROUTER. That is thanks to new board that has similar structure as RB450G where debug mode or MetaROUTER can be monitored (it cannot be done or RB450G).

Fingers crossed it crashes again.

some details - Router was just idling same as metarouter, and then it rebooted.

Re: RB450G + openwrt Metarouter strange problem

Wed Sep 28, 2011 2:45 pm

Ok, my new Metarouter test crashed after about 3 hours.

Short sketch of the config:
1 Metarouter, 32MB RAM&Disk
2 Virtual Interfaces, one dynamic as bridge port, one static to ether2.
Pinging from Metarouter to host.
Pinging from another System connected at ether2 to Metarouter.
Only things configured in Metarouter where one IP per interface and System name.

Packages:
/system package print
Flags: X - disabled
 #   NAME                    VERSION                    SCHEDULED
 0   routeros-mipsbe         5.6
 1 X ipv6                    5.6
 2   system                  5.6
 3   mpls                    5.6

11   dhcp                    5.6
12   ntp                     5.6
Switch all ports ist still set to yes.

I'am sorry, but that is about all I can supply as tests by now.

Your devs forgot to include the AR7116 in the JTAG scan chain on the RB450G? ;)

Here is my final log of this test... so it's no working solution...
Now all metarouter interfaces have been disabled again, and it runs stable, but no network to the virtual machines.

I have, yet again, a useful purpose for a metarouter.

I guess you only could try yourself, there is extremely less feedback on Metarouters altogether.
And, without wanting to bash MT, there seems to be no clear understanding of the cause on MIPSBE, so every MIPSBE based board should be viewed as affected. Even a small software update might tip those boards over the edge.

If people are asking for progress and we don't get any answer, why would you characterize my comments as spam?

@xdemon: I've never reached 24 hours uptime on 750GL with MetaROUTER activated (with OpenWRT guest). I don't know about ROS guest, didn't test. And btw, the VM was doing very light DNS traffic for home LAN.

I don't think it's traffic related. I don't really use mine except for testing now and then and it reboots often enough.

unfortunately it is all I can disclose. and even then some of info is just a guess :(

so, there are reports of metarouter hanging on RB450G and RB493G. Anyone with RB435G or RB411AH can try metarouter on it?

for me RB433AH does not crash. Now stuck with RB450G that does not reboot :?

Re: RB450G + openwrt Metarouter strange problem

I can only repeat and clarify what I said in earlier posts:

The whole MIPSBE series should be considered unusable in combination with Metarouter.
Especially with the information available from MT and the fact that they aren't capable of fixing this problem in such a long time.

@MT:
This is not intended as pun, just as a warning to everyone planing on using Metarouter on MIPSBE based MT boards.
And don't start repeating that Metarouter is stable on "some" MIPSBE boards, this is just plain luck and might change with every change/release you make.

It doesn't stable even with routeros virtualized. Crashed after 10 mins with router reboot. metarouter-fs used 40-80% of cpu first 3 mins. I have autosupout.rif file, but i can't find enything useful in it.

UPD: looks like it working after reboot.

Is this problem isolated to MIPSBE or all BE processors? LE architectures do not have the problem?

If so, those are huge clues.

MIPSLE boards do not support metarouter, hence - they do not suffer from this problem. As far as i know various RB4XXG models do suffer from this problem (RB493G, RB450G, RB435G). Never seen this problem on RB433AH and similar.

And yes, this could have an influence but at a point where it's already to late out of a developers perspective.

le, is x86 and mipsle, both of the does not have MetaROUTER.

and this problem is not out of devs perspective. Just there is not a reliable way to reproduce it. As sometimes something starts to happen after 2 weeks other time, restarts happen once in 10 minutes.

Interesting. I did not know le, and in particular x86, doesn't support metarouter! This saves me a hard lesson.

And yes, there is something i discovered in process of testing:

1) netconsole. There is no error logs sent via network - only standart boot data.
2) There is no crashdumps in openwrt machine. Basically everything is okay with openwrt.
3) i tried watching dmesg, and there is no error messages too.
4) Mikrotik MetaRouter (with RouterOS machine) sometimes hangs too.
5) And... sometimes reboots of router (physical, not virtual one)

So... this is 100% RouterOS fault. I sent supout file to mikrotik.

P.S. if we only had access to more verbose logs...

Some interesting info. I enabled writing debug logs to disk, and tried to catch some messages.

Of course i haven't found any useful info, but...

There were no virtual machine freezes
Instead, router crashes hard. I always saw that first virtual machine freezes, and then router crashes (if you do not disable VM via /metarouter _before_ router crashes - if you will be fast and disable VM router will not crash)
I tried that, well, somewhere around 10 times. VM _do not freeze_. Router crashes anyway...

Maybe that somehow related to filesystem?

I am just using metarouter so I can load OpenVPN into OpenWRT to use UDP as the transport protocol. If MT could just add the UDP option for OpenVPN instead of only TCP I bet it would solve some problems out there.

Maybe a x86 Board like Soekris net6501 with KVM will be more usable; I didn't try.
I just use MikroTik/ROS for testing and home usage and gave up all planned and realized productive installations.

Re: RB450G + openwrt Metarouter strange problem

Thu Feb 02, 2012 6:08 am

Perhaps the problem is really in miscalculations in the design of power converters on the routerboard 450G. With a standard external power supply DVE DSA-20P-20 24V/0.8A router, when running metarouter, was unstable and often restart at arbitrary times, even in idle mode. ROS 3x, 4x, 5x - no difference. However, with the simple old transformer power supply 12V/0.5A router works fine for more than a day, with a test load in the form of Ping Speed between the router and metarouter (average 163 Mbps at a reduced up to 400 MHz cpu clock).
By the way, lowering the CPU clock from 680 MHz to 400 MHz did not affect the instability.
When using low voltage power supply, became less warm coils and capacitors in both the power converters to 3.3V on routerboard, which is an indirect proof of engineering miscalculation. And stronger heated coil, which supplies the switch chip and memory. In this scheme fits the fact, that router is a bit more stable in the mode "switch-all-ports=no".
IMHO, the designers of this model were to use a more powerful power converter, similar to that used in RB433x.
Another is the idea of replacing the electrolytic capacitors on the solid polymer capacitors. It is not excluded, that this may also solve the problem.

ps Forgive me my nice Google English :)

the frequency of reboots of the board is not connected to PSU in any way, of course, board has to have enough resources. It was tested at full CPU load.

I guess you only could try yourself, there is extremely less feedback on Metarouters altogether.
And, without wanting to bash MT, there seems to be no clear understanding of the cause on MIPSBE, so every MIPSBE based board should be viewed as affected. Even a small software update might tip those boards over the edge.
It's not just the MIPSBE, I have the same behavior with PPC platform, RB1000 and RB1100AH tested.
My bet is that the MetaROUTER software is unstable.
Have anyone configured the guest interfaces in dynamic mode only?
I'm wondering if the setup of static interfaces is not correctly configured in the underlaying Linux kernel.
I was convinced that static interfaces is a HW bypass directly to the guest, but I don't think so any more.

Can you elaborate on this? What specific configuration changes resolve MR issues on PPC routers?
Is there a wiki of sorts?

I had given up on Metarouter until mipsbe becomes stable. But if ppc is stable....

I'm installing an RB1100AH next week and could use MR for lots of things - if ppc Metrouter is stable.

Timberwolf, so your opinion is not to use MR at all, at least not until a stable version is available? ;)
Yes, that is exactly my opinion.
And my impression is, that this will be never.

So, your saying MR in general on all platforms including PPC platform?
And you're not agree on the statement? :

Do you have any experience of ROS x86 KVM stability?

Tweaking your configuration until the system runs stable isn't a solution.
At best that's a workarround and nothing you let your customers play with.
Do you have any experience of ROS x86 KVM stability?
No. I would like to think that this configuration might be usable, but I am unwilling to take the risk.

I'm starting to suspect that whoever wrote the MR code isn't longer working for MikroTik. So MR might be considered an abandoned technology.

Totally agree on this.
As long there aren't any description and manuals provided with confirmed and tested configurations, the MR aren't usefull.
No. I would like to think that this configuration might be usable, but I am unwilling to take the risk.
I will setup an x86 appliance for heavy tests the KVM.
I'm going to test it exactly same way as I'm testing the MR

good, waiting for your results.
Some results, or to be more precise, different config settings between MetaROUTER and KVM.
Janis! correct me if I'm wrong about my assumptions and conclusions.

I'm trying to understand the different configurations based on my Linux knowledge and how-to configuring tun/tap, vlan and bridges in Linux OS.
When creating static interfaces in MetaROUTER, you can select physical interfaces like Ether1.
The selection list on KVM show only the interfaces already added as Virtual Ethernet interfaces. (/interface virtual-ethernet)

In MR, if I use a physical (not configured on the host) interface in a guest and add VLAN on that interface on the guest, the VLANs works.

To do the same thing in KVM I need to create a bridge with a tap interface and the physical interface I want to bind it to.
The tap interface is the interface that is attached to the guest.

If I create the same configuration in MR with a bridge between a physical and virtual and the vif attached to the guest, all interfaces stops responding.
I have arp in the guest and the bridge host table looks alright, but the guest is not responding.
The difference between the configuration of virtual ethernet interfaces, is that in KVM you can assign MAC-address on both host and guest side, but not in MR.
If I, in MR, change from static to dynamic and assign the interface to the same bridge it all starts working again. And now, it assigns a MAC-address on the host side.

From Winbox (2.2.18) I can add and view Virtual Ethernet interfaces in KVM, but not in MR.

Is the MetaROUTER paravirtualization or just a software on the hosts that emulates a ROS?

More to come.....

this one is interesting, now if you could give full configuration of the "same" configuration would be nice (to avoid confusions. That is mipsbe router?)

when you assign physical interface to MR tap interface is tapped into the physical interface well before a lot of stuff that works with packets in RouterOS. There are some services that can get packets on the host from that interface, but could not work around that. In KVM that is not possible. When transmit happens from MR packets are put into interface send buffer and interface just sends them out (as it usually does, as interface only concern is OSI Layer1)

MetaROUTER is not just ROS emulation, as it is possible to have OpenWRT and, as some reports say, debian running as guests. Similar to KVM, MR requires CPU virtualization support.

RouterBOARD routers will not have Virtual Ethernet tab, instead use filtering to filter out virtual interfaces if you have a lot of interfaces on the router.

the frequency of reboots of the board is not connected to PSU in any way, of course, board has to have enough resources. It was tested at full CPU load.
Maybe ... However, with a 12 volt transformer PSU 450G uptime for over 5 days. However, I did not banished tests this time, but with a 24 volt PSU uptime does not exceed several hours even under no load.

i have ability to set PSU voltage to value i desire in range where RB450G is working and change of that did not change stability of the setup. Maybe you could list what amperage you get at what voltage from these PSUs?

edit: check in what condition are your capacitors.

OpenWRT is heavily patched to run on MetaRouter. I seriously doubt you can get anything to run without heavy modifications, e.g. full paravirtualization.

Are you sure MetaRouter does hardware virtualization on MIPS?

Transformer PSU used DVE DV-1250UP 12V/0.5A
450G when operating this PSU at idle consumes 0.36A with running Metarouter and 0.31A with a stopped Metarouter

The problem with the electrolitic capacitors Suxxon me know :) see here and here. These capacitors from the main DC/DC converter (7...28V to 3.3V) were replaced in advance by electrolitic Nichicon 1000.0/6.3V, combined with a faulty motherboard. The input capacitor 330.0/35V I have not replaced, he works in a relatively comfortable conditions.

In the plans to test the stability of pulsed PSU Powertron PA1008-2DE 12V/0.5A. And how will his free time, to measure the waveform at several control points on the power rails. It also plans after checking power supplies want to replace electrolytic capacitors with polymeric and verify with the standard 24V PSU.

p.s. There is also a possibility that could fail PoE switch logic, such as short-term switch, which is why just lost power. Unfortunately, I have no design scheme to say this objectively.

Stability test with a pulse PSU Powertron PA1008-2DE 12V/0.5A is successful. RB450G uptime 5 days.

with all links active and with CPU loaded 0.5A @12V can be too short. You could be lucky with any other PSU. But good to hear that you have it running for 5 days now.

No, only four active link and a regular on an Internet surfing. But even in this mode with 24V PSU uptime does not exceed several hours.
"Native" 24V PSU tried two things - with both equally unstable.
p.s. It is still checking PSU. Ahead - a study with an oscilloscope. ))

Really, oscilloscope? End result. The feature seems to just not work.

Re: RB450G + openwrt Metarouter strange problem

Thu Mar 22, 2012 11:10 am

Today I began to test Metarouter on RB493G platform, ROS5.12

I'm runing defult configuration on host router and two MR - one with ROS 5.12, the other with DDWRT images from this manual http://wiki.mikrotik.com/wiki/Manual:Metarouter.

Every router has one static and one dynamic port. Thats all.
I'v got 3 crashes ( with systems reboot) with interval from 15 to 90 minutes.
I see that RB45x and RB49x devices not sutable for MR feature about 3 years :shock:

Could anybody answere below question?

1. Does this problem deal with only DDWRT or ROS Virtual machine too?
2. How it works on PPC architecture?
3. What device is the most stable for runing MR wit ROS Image? How long uptime they have?

As you can read from my previous posts, the MR aren't useful in any platform.
If you want virtualization in ROS, go for x86 platform and run KVM (Qemu) guests.
