Perhaps you would give kdump a try, which allows to store the crash log and the memory image to another computer or even the same, depending on how serious the crash is.
The crash is complete and final.
I need something that dumps data while the crash is happening with no user intervention whatsoever, to another computer, and as low level as possible, as I don't know what still works at that instant. Maybe nothing. Years ago I would consider serial port, but the second machine has none.
Try http://doc.opensuse.org/documentation/html/openSUSE_114/opensuse-tuning/cha..... Kdump is a mechanism to kexec a new kernel, which is stored in memory explicitly reserved for it when the running kernel hangs. After that, it should send the logs over the network or save them to local filesystem, but the latter is risky if the filesystem causes the crash. Last time I used it, I recall that the default amount of memory reserved was too low for a modern initrd. If you don't set it high enough in Yast, the kdump image fails to start without displaying any error. -- Regards, Peter -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
