Hello Everyone, We have noticed that one of our servers xen Dom0 is restarting idiopathically. Atleast, we are not able to analyze the cause. I have checked the logs but couldn''t find anything relating to it. Are there any tools such as kdump (which doesn''t seem to work on xenified kernels) for catching the kernel crash snapshot. Regards, Sree Harsha Totakura Member, Open

Hi, Is netconsole supposed to work under pvops? When I try to enable it I get the following: Initialising Xen virtual ethernet driver. blkfront: xvda1: barriers enabled netconsole: local port 11111 netconsole: local IP 10.20.40.2 netconsole: interface eth1 netconsole: remote port 9514 netconsole: remote IP 10.20.50...

...SSH on such devices and start SSH automatically when the system boots so people can login. This works pretty well but sometimes a device stops to boot for no good reason. This is usually really hard to debug since we don't have any logs at all. For kernel messages, I could probably activate netconsole in the kernel. Even this is a bit tricky since we often cannot change the kernel cmd line but I could probably use klibc in the ramdisk to setup the network and then configure a dynamic netconsole. My big concern is with userland messages, though. I want to see what the ramdisk is doing, ideally...

When a bridge interface deletes its underlying ports, it should notify netconsole too, like what bonding interface does. Cc: "David S.

We have a setup with 15 hosts fibre attached via a switch to a common SAN. Each host has a single fibre port, the SAN has two controllers each with two ports. The SAN is exposing four OCFS2 v1.4.2 volumes. While performing a failover test, we observed 8 hosts fence and 2 reboot _without_ fencing. The OCFS2 FAQ recommends a default disk heartbeat of 31 - 61 loops for multipath io users. Our initial

Appologies in advance if there is an obvious answer to this. I'm experimenting with netconsole. When I try to insmod the netconsole module it complains that eth0 doesn't support polling. Any idea where I can find a list of supported NICs? How can I workout if a NIC driver supports polling? Many thanks Daveh

Hi, I'm in the position that a network console would occasionally be very useful for me to control pxelinux. Has the possibility of adding it (next to VGA and serial) been ever discussed? I understand that it may sound somewhat contorted, but it could also serve instead of a TFTP PUT for extracting hardware info, for example... How hard would it be to add (considering gPXE as well)? --

...: Marcin Slusarz <marcin.slusarz at gmail.com> --- Let me tell you little story about this patch... It took me ~week to figure it out. 1) I bisected it to "drm/nouveau/gpio: port gpio to subdev interfaces", but looking at this commit I couldn't spot anything (who would...). 2) Netconsole hanged immediately on boot (I found the commit which broke netconsole and it turned out to be already known broken with patch fixing it waiting for pull). 3) Even with netconsole working, completely nothing reached netconsole across S/R - I had to add no_console_suspend on kernel command line to se...

Hey! I''m deploying a vanilla Xen 4.1.2 installation at a hosting provider, and I''m experiencing hard hangs (i.e., the system is unresponsive to keystrokes, network is off, I/O to disk is stopped) on several of their available server packages, all based on Intel i7 CPUs and related chipsets. The failure does not seem related to a specific Xen-version (I''ve

...he first call normally gets through. If I start the second or third call and sometimes when I terminate the first call, the system panics (Oops text on console). After solving some difficulties (the relevant part of the Oops text scrolls out of the monitor, no serial interface), I get the text via netconsole. It seems to me, that the panic occurred in oslec (function "oslec_update"). But maybe I am wrong with this. In the oslec code there is a patch to enable MMX. After switching this off, the problem disappeared. AFAIK the cpu supports mmx. Where should I address this issue to? Is it a know...
