Scheller - 2016-12-14 16:50:26 == ---Problem Description--- On a KVM guest installed to a multipath root device, the kdump kernel fails to mount the root file system. This error does not occur in a similar guest installed to a single path device. Full console output of the kdump failure is attached.

Yes, the guest has only one disk. That disk is actually a LUN from a fiber channel storage device with two paths on the host side. I have passed through both paths to the guest, so the multipath nature of the target disk is known to the guest. In other words, the guest sees a multipath device and is using it as a multipath device. The root file system is called /dev/mapper/mpatha-part2 on the guest. > - how did you attach the device to the guest? Each FC LUN path on the host is mapped to a virtio-scsi controller on the guest using LUN passthrough.

I think it theory is doesn't seem so, but the reality is that _for some reason(s)_ we require just too much memory to load and boot a kernel/initramfs (either on boot or kdump). When working w/ kdump and Ubuntu, I usually set the crashkernel allocated size right away to 4GB to avoid problems. Since this is a smaller sized guest, obviously we'd want to use less than that, but more than 512 MB given the evidence observed. Hope this helps == Comment: #28 - Mauro Sergio Martins Rodrigues - 2017-01-13 10:12:28 == >I think it theory is doesn't seem so, but the reality is that _for some reason(s)_ we require just too >much memory to load and boot a kernel/initramfs (either on boot or kdump). For the record, as you already know, I've raise memory up to 1024mb and it didn't help. >Per yesterday's conversations, this had to do with IRQ distribution and the nr_cpus kernel parameter, >and seemed to affect multipath only by chance, usually failing/hanging the guest at kdump at other >parts / way earlier in boot (at virtio-scsi disk probe phase too). Yes, that's right. So looks like there are a couple of things going on here. The first and simpler: According to kdump's documentation at https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/kdump/kdump.txt#n365 noirqdistrib is a necessary parameter for use kdump in ppc64 architecture, and indeed it solves the issue, including the case when nr_cpus=1 (which was failing in all my attempts until I used noirqdistrib). So I believe a patch in ubuntu's kdump package to set that attribute for ppc builds may solve this definitely and that will be my focus for right now. Nevertheless I will keep investigating why this issue is happening only w/ multipath devices. == Comment: #29 - Mauricio Faria De Oliveira - 2017-01-16 04:22:00 == (In reply to comment #28) > >I think it theory is doesn't seem so, but the reality is that _for some reason(s)_ we require just too >much memory to load and boot a kernel/initramfs (either on boot or kdump). > > For the record, as you already know, I've raise memory up to 1024mb and it > didn't help. Definitely. What I've observed is that more than 2GB (yes..) was required on some systems I checked on at the time. Since you've identified the IRQ distribution aspect of this issue, the crashkernel memory size might not be completely related to this problem, and for this system, the configured sizes happen to work well. > Nevertheless I will keep investigating why this issue is happening only w/ > multipath devices. Based on the IRQ distribution aspect, the most reasonable suspicion I've thought of is... In our testing, several times I observed the kernel initialization to hang in the probe stage of the virtio-scsi disks, and the IO request (probably for the partition table read operation) would time out (signaled by a 'tag abort' message). If we suppose that these initial IO requests passed correctly (say, these initial IRQs happened to be assigned the the CPU that was online, and thus were delivered/handled correctly) BUT the IO requests issued by multipath (for disk/path identification) fail (i.e., happened to be assigned to a CPU that was offline, then these requests would time out), then multipath would never get a response back, thus not initializing the individual paths and the respective multipath device. So the /dev/mapper/mpathX device is not created, and the problem is observed. [Impact] On Power Systems, some interrupts are missed, and dumping the crash will fail. Adding the noirqdistrib kernel parameter to the kdump kernel will fix this. [Test Case] Setting up kdump to target a virtio-scsi device on a Power System. [Regression Potential] The parameter could be interpreted differently on a different platform and kdump would fail. However, it has been verified that no other platform uses such parameter. If another parameter would have been incorrectly removed on the patch, kdump could fail on other systems. == Comment: #0 - Richard M.
