XCP-ng 7.5 - MegaRAID SAS 9240-8i hang/reboot issue.

Let us see if a newer kernel would help. There is also an option of back porting the newer driver to older kernel with possible code changes. Both will be experimental though!

Same thing happens in XS 7.6 "upgrading" from XS 7.5. Interenstingly enough post upgrade, the upper-left corner says Xenserver 7.5 but the stats field and Xencenter report 7.6.
Same thing happens in a clean installation of XS 7.6 too. -
@mpyusko Let me see if we can build driver 07.703.05.00-rc1 for your XCP-NG 7.5/6, will let you know if it becomes available.

@mpyusko Please get the driver from link and
[root@xcp-ng-rjv ~]# yum install megaraid_sas-07.703.05.00-1.x86_64.rpm
[root@xcp-ng-rjv ~]# rmmod megaraid_sas
[root@xcp-ng-rjv ~]# modprobe megaraid_sasThen check for your lspci.

@mpyusko If I understood correctly,
lspci -vv -s 07:00.0is crashing the host? Even on megaraid_sas version 07.703.05.00. But Kali linux host does not crash on same megaraid_sas version.To resolve this, Do you have console access to the host? or remote KVM?
I would suggest you to boot your host in "XCP-ng in Safe Mode", this menu comes up when you start to boot the host. Instead of default "XCP-ng" choose "XCP-ng in Safe Mode".
This will allow us to see the messages generated in kern.log or onscreen about the crash and would point it right to the problem.
Meanwhile if you have some stack trace logs in kern.log, please share those.
-
Yes, you are understanding correctly. I have Root, Console, iDRAC, KVM and physical access to the machine
The SEL reports:

The only thing "odd" about this server is I pulled out the PERC 6/i controller and installed a brand new LSI controller because I my drives exceed the 2TB limit of the PERC. Even when idle in Maintenance Mode, it will still randomly reboot with the same SEL output. This makes it too unstable to run for production, or even a dev environment. It could be minutes, hours, or days between random reboots. Probably due to the kernel accessing the controller for some health check or something. In Maintenance Mode, there are no VMs running, just XCP-ng, and that's it. The system is on a conditioned powersource with battery-backup. So I am ruling out dips and spikes. The iDRAC also reports on power quality, usage, and health. Everything is good. As I said before, this does not happen under Kali. I probably have other boot flashes for other OSes and distros I can try. But the fact is, if it was hardware related, then it would never be stable.
-
We'll have a more recent kernel to test, thanks to @r1's work. This could be interesting to test I suppose.

Unfortunately, the NIC drivers are not configured for this boot flash, so I can't copy and past the console output.
-
@mpyusko I'm surprised that the host is "rebooting" even after having in "safe-mode" thats not expected behavior.
Step1:
I know only one situation in earlier Xen days (3.x) when BIOS CPU C-states were causing CPU to black out, resulting an undetectable crash. To rule this out, please set your server to "performance mode" from BIOS so that it does not try to enter in power save mode randomly.Step2:
Please have your grub Xen line updated as
multiboot2 /boot/xen.gz noreboot no-mce ....Step3:
A newer version of driver is released on 12 Sept, 07.707.00.00. I'll make that available for you to isolate the "driver" to be the reason for crash.Step4:
I have a test kernel which may fix this issue - or at least help us isolate "kernel" to be the reason for crash.[root@xcp-ng-kernel ~]# modinfo /usr/lib/modules/4.9.133/kernel/drivers/scsi/megaraid/megaraid_sas.ko | grep -i ver filename: /usr/lib/modules/4.9.133/kernel/drivers/scsi/megaraid/megaraid_sas.ko description: Avago MegaRAID SAS Driver version: 06.811.02.00-rc1 srcversion: E452D341082401C48444BC7 vermagic: 4.9.133 SMP mod_unload modversions [root@xcp-ng-kernel ~]# uname -a Linux xcp-ng-kernel 4.9.133 #1 SMP Sun Oct 14 15:48:31 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux [root@xcp-ng-kernel ~]# -
@olivierlambert It will be. Kali with 4.15 and Debian with 4.9 both do not exhibit the issue. However Xenserver and XCP-ng both do. I'd be interested to compare their compiler settings as to what they do and do not include.

I just received an LSI SAS-9211 I ordered. I have the exact same controller running in a production environment for a web-hosting company. Similar architecture (HP DL380 G6) and it operates flawlessly with XS 7.1 so I figured I would try on in this machine. Initially I wanted the 9240 for it's hardware based RAID6. However with ZFS support rolling out in the new versions of XS/XCP-ng, there are greater gains to be had there. So opting for a different JBOD mode controller was a fair choice.
Interesting things to note.
- Both brand new LSI cards
- they each use different drivers.
- 9240 supports a broad range of RAID levels 0,1,10,5,6,etc and JBOD
- 9211supports RAD levels 0,1,10, 1E/10E and JBOD
- My system was originally configure for two drives in a 1TB RAID1 volume and 4 drives in a 9TB RAID5 volume.
I removed the 9240 and installed the 9211 making sure the port 0 = 0 and 1 = 1. I then booted the system and entered the LSI setup. unlike the 924, there was no option to import existing arrays. Rather than detsroy everything on the 1TB array (the 9TB was still empty) I opted to just boot straight to XCP-ng 7.6 without any changes. The last time I shut down the server I detached all the storage volumes from the VMs. (A quick trick I learned... detatch volumes, export VMs - only takes a couple minutes and a few KB - then dd flashdrive to backup flash. Upgrade Xen, reattach drives. Keeps you from risking your data, especially on critical machines.) When I booted this time, all the SR's were broken but a quick repair brought them back and when I reattached the volumes, the VMs booted. Remember this was originally a Hardware level Array. I'm still trying to peek into the Array to see if both drives are functioning, but appears healthy so far.
The big question is will the system still generate the same issue? Well, one is a megaraid controller and the other isn't so they use different drivers. Here is the output...

@mpyusko BTW.... Yes, it did "repair" the SR, but it did not rebuild the array. It is functioning off one drive only. the other is now out of sync. Not a perfect transition, but it's nice to know my data isn't lost by simply swapping adapters. Clearly I'll need to build a software array to rectify the issue.
