Description of problem: When use usb storage devices as dump target, the second kernel failed to find use storage device. This cause kdump failed to dump vmcore to usb storage devices. If config kdump as: ext3 /dev/sdb1 Second kernel failed to mount /dev/sdb1. If config kdump as: raw /dev/sdb Second kernel will just dump vmcore to /dev/sdb, even this /dev/sdb does not exist. Version-Release number of selected component (if applicable): Latest RHEL5.7 tree kernel-2.6.18-270.el5 kexec-tools-1.102pre-132.el5 How reproducible: 100% Steps to Reproduce: 1.Config usb storage device as dump target 2.Trigger crash via sysrq-c 3. Actual results: Kdump failed Expected results: vmcore saved Additional info: Also tested RHEL5-U6-Server, don't works too.
Dup of Bug 716338?
(In reply to comment #1) > Dup of Bug 716338? No, I think. Second kernel failed to find USB storage device, this caused kdump failed.
Yeah, please provide the console log of the second kernel if you can reproduce it. I don't have a RHEL5 machine with a USB disk plugged. Or, if you can find such a machine from beaker, it is definitely nicer to loan it to me to investigate this. Thanks!
I have verified it with raw and ext3 format of USB device. The system could be dumped to the USB device successfully and vmcore file could be found after reboot. Hence, this bug could be cancelled.
