Hi, is there some way to trigger sysrq from the serial console in xenlinux? With native linux it works by sending a break + sysrq letter, in xenlinux it doesn''t work that way though ... cheers, Gerd -- panic("it works"); /* avoid being flooded with debug messages */ ____________________________________________...

Hi, I tried to test a wrong operation on purpose again. When I tried xm sysrq command to a inactive managed domain, I saw the following error message. The error message did not have a message text behind "Error:". And I found an AssertionError message in xend.log. # xm list PVdomain.1 Name ID Mem VCPUs State Tim...

Hi everybody, I am using btrfs as my main fs for some time now, but I am experiencing severe performance drawbacks. I can''t qualify the circumstances, but sometimes during disc access the whole system freezes for some time. Maybe somebody could suggest some general things I could try to search for the problem? Thanks in advance, Florian --- Some background information: $ mount |

Hello, Without using XM, is it safe to write the letter corresponding to the desired sysrq to xenstore in /local/domain/domid/control/sysrq ? Does anything else have to happen? I am working on some backup utilities that utilize the lvm2 library (liblvm2cmd) , libxenctrl and libxenstore. The program will issue a sysrq S to a guest, pause it, take a snapshot then unpause it (all very quic...

I am having trouble sending sysrq commands over USB serial, and I'm not sure what else to check. I have two identical machines, each with usb-to-serial adapters, joined by a null modem adapter. One runs an agetty, the other minicom. I can log in over the agetty as a user and it works as expected, until I try to send a sysrq....

Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generate...

...g starts), nouveau has been working quite well during the most of the time. However, my screen gets locked up sometimes, while the mouse can still move(I guess that's because of the KMS?). Eventually I noticed most of the hang-ups occur when I am browsing with Google Chrome. If I simply press SysRq + E, nothing interesting will happen. However, if I press Alt + F1 then Ctrl + Alt + Delete, I can get my terminal output back, with mouse pointer still on it(and still be able to move). When the system is rebooting, I noticed some interesting output generated by nouveau kernel module, unfortunatel...

Hi all, Are there equivalent xe subcommands to ''xm sysrq'' and ''xm dump-core''? I looked up xe''s help message and hidden subcommands in source code but cannot find. -- Regards Yu Zhiguo _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/...

I have a KVM guest running on CentOS 5.5 that is in a bad state. I would like to dump the kernel information using magic-sysrq commands, but I cannot figure out how to send a break on the virtaul serial port provided by "virsh console". The guest is a standard install that will respond if I can send a break on the virtual serial port. Is it possible to send a break on the virtual serial port? Thanks, David

I am using CentOS 5.6 as a KVM host. My guests are running CentOS 5.6 with the only console being a virtual serial console. The guests are configured so magic-sysreq can be used to debug kernel issues. However, in order to send magic-sysrq from a serial port, I need to send a break. How does one send a break on the virtual console serial port provided by KVM/libvirt to guests? Thanks, David

...abases OCFS2 isn't being used by RAC, we're using ASM for that, but OCFS2 is used to provide a shared /usr/local, /home and /apps. Yesterday I discovered something very unexpected. ? I shutdown node B to single user mode, and immediately node A crashed. The only message on the console was SysRq Resetting.? Node A then rebooted normally. I then exit single user mode on node B to jump back up to run level 3 the system started up ok, but no sooner had I got the login prompt on the console when it too crashed with SysRq Resetting. I repeated the steps for a second time and it did exactly the...

...a crashed kernel, and so the only way for kdump to dump a kernel is to crash it and cause kdump to invoke its post-crash kernel. You can manually force a running kernel to panic (and invoke a correctly-configured kdump) with the following command sequence: > echo 1 > /proc/sys/kernel/sysrq > echo c > /proc/sysrq-trigger Cheers, Ben On 3/25/19 7:19 PM, wuzhouhui wrote: > Hi, > > Is there a way to specify kernel version when (re)start kdump > service?

Hello, when I start a second X server or when I suspend (and resume) to ram compiz crashes. I tryed to debug this but its impossible to run gdb on compiz (=freeze). This happens with current git, but If I remember correctly not with 0.3.6 (and git versions < 0.5.0 but I don't know when it started to happen). any ideas?

I''m using btrfs on two devices here, /usr on sda3 and /home on sdb (dm-crypt device on the whole disk). With btrfs-master the whole system hangs when accessing /home. The system hangs when I''m logging in into my account with KDE and is easily reproducible with dbench. On /usr the hangs appeared also but not as often as on the /home-device. I''ve tested on a third
