Regarding memory test: Just running the normal mem test from Grub should do, I guess?

RE: XCP-NG server crashes/reboots unexpectedly
@stormi Thanks. I've gone through the kern.log.1/2/3 etc and I can see when the server seems to have rebooted and comes back up again, but there doesnt seem to be anything logged just before it quits.

RE: XCP-NG server crashes/reboots unexpectedly
@olivierlambert I looked through the xensource.log.1/2/3 etc files.
What sticks out to me is that there is a gap here:
xensource.log.2's last four lines: Nov 19 16:43:27 xcp-ng xapi: [debug||3064510 /var/lib/xcp/xapi||dummytaskhelper] task dispatch:SR.scan D:*** created by task D:*** Nov 19 16:43:27 xcp-ng xapi: [ info||3064512 /var/lib/xcp/xapi||taskhelper] task SR.scan R:*** (uuid:***) created (trackid=***) by task D:*** Nov 19 16:43:27 xcp-ng xapi: [debug||3064512 /var/lib/xcp/xapi|SR.scan R:***|message_forwarding] SR.scan: SR = '*** (20TB HDD)' Nov 19 16:51:30 xcp-ng xapi: [debug||3069218 /var/lib/xcp/xapi|session.slave_local_login_with_password D:***|xapi_session] Add session to local storage
Then the next four lines are in a new xensource.log.1 file, but notice a 49 minute gap until then:
xensource.log.1's first four lines: Nov 19 17:40:08 xcp-ng xenopsd-xc: [debug||5 ||xenops_server] Received an event on managed VM *** Nov 19 17:40:08 xcp-ng xcp-rrdd: [ info||9 ||rrdd_main] memfree has changed to 4191660 in domain 9 Nov 19 17:40:08 xcp-ng xenopsd-xc: [debug||5 |queue|xenops_server] Queue.push ["VM_check_state","***"] onto ***:[ ] Nov 19 17:40:08 xcp-ng xenopsd-xc: [debug||40 ||xenops_server] Queue.pop returned ["VM_check_state","***"]
I've redacted some UUID's with ***, probably wasn't needed but just in case.
From the earlier graphs I expected to not see any log here (assuming the machine was off or whatever), but it seems it was actually running most of the time. The above 49min gap seems to be the only longer gap I can spot at first sight in the last days log. Strange because in XOA the graph shows as if the host was down for like 23h or so. Any thoughts?

RE: XCP-NG server crashes/reboots unexpectedly
@olivierlambert Hi, do you have some pointers which exact files to check for those?
I've looked at:
- /var/log/xensource.log, but that log seems to have started earlier today. I don't see entries back to when the reboots happened.
- Regarding IPMI logs: This machine is a Ryzen 9 5950X on a Asus Prime X570 Pro motherboard. It doesn't have IPMI unfortunately.
I will look into doing a memtest as you suggested.

RE: XCP-NG server crashes/reboots unexpectedly
I took a look at the performance graphs in XOA and the two reboots can clearly be seen. What looks interesting to me is that the server seems to have stayed offline for quite a while (when there are no data points in the graph) ? And only then came back up. Also after the 2nd reboot there seems to be a high load average, even though only one VM is on auto-start (xen orchestra) and no other VMs were started yet.
Anyone who can make something of this? It seems weird to me that whatever induces a reboot of the system would not bring it up directly again, but in fact have varying durations until XCP-NG+XOA is back up, according to the graphs. Based on this, it seems after 1st reboot it was down for ~3h. After 2nd reboot it was down for about ~23h.
Also note:
- This server was running stable in this exact configuration for almost 2 years now.
- I have two other pretty much identical servers that do not have this issue (same rack, same power source)

XCP-NG server crashes/reboots unexpectedly
Hi,
In the last 1.5 weeks my server seems to have rebooted itself at least two times. I noticed this because my VMs weren't running anymore. It seemed like a fresh reboot of the server. I want to figure out what the reason is and fix the issue. I started looking at logs i.e. at /var/log/kern.log and the /var/crash folder, but both file and folder are completely empty.
My conclusion on the above kern.log and crash folder being empty is that it probably wasn't XCP-NG crashing causing the reboot.
My conclusion would be that its likely power (PSU or motherboard) related. Any other logs I should check/or any other comments you may have (on my conclusions above) ?
Thanks!

RE: Questions about backup features
@CJ said in Questions about backup features:
I have one schedule that runs daily to perform a delta backup and then a second schedule with force full backup enabled that only runs once a week. Make sure you remove the weekly full backup day from the nightly schedule or you'll have both backups happening.
@CJ just curious: why would you do a full backup once a week? In principle your remote delta backup will already stay "up-to-date" with just the delta backups right? Or am I missing something?

RE: PCIe USB card (and PCIe bridge) disappear after host reboot
Yeah.. this definitely was a nightmare, I am taking a few days off after this

RE: PCIe USB card (and PCIe bridge) disappear after host reboot
After another full day of troubleshooting it looks like I found the issue..
Installed Ubuntu Server and tested the plugged in USB cards that were detected to figure out which one was the one dropping out. Turns out if that card is in any of the PCIe slots it will cause the issues seen. If its not installed in the server no cards disappear.
I've removed an identical and known working PCIe USB card from my 2nd machine and replaced the faulty one. It seems everything is working fine again. Quite interesting how a faulty card resulted in this rollercoaster of symptoms seen.. at least some nice lessons learned for the future

RE: PCIe USB card (and PCIe bridge) disappear after host reboot
Tried some more things but nothing resolved the issue:
-
Put RAM speed from DDR4-3200 to AUTO -> Same issue
-
Put a different GPU (removed the Nvidia K2200 GPU) but still breaks when i.e. starting with 0 plugged in SATA devices to plugging in 1st SATA HDD.. -> Same issue
-
Reseated CPU and checked for any bent pins (looked all OK) and re-pasted it -> Same issue
-
Tried using different output on K2200 GPU (output 2 (DP) instead of usually output 3 (DP)) -> Same issue
-
Tried without any GPU at all (also not onboard GPU, as this CPU doesnt have integrated graphics) -> Same issue
-
Took out PCIe USB cards one by one (had no GPU installed at all while testing that, had 10gig card in top PCIe slot for a change, and 1x HDD attached via SATA). Then removed one by one the PCIe USB cards:
^Every time I remove one and boot, it shows the correct amount of PCIe USB cards first time. Then after reboot always one PCIe USB card-1 less.. That amount then also seems to stay across reboots. However, when only one PCIe USB card is left, that card seems to stay recognized and does not disappear after a reboot! -
Reset bios settings (still using latest BIOS version) by removing battery and shorting RTC reset pins. Left bios at untouched defaults and booted into XCP-NG -> Same issue
-
Removed all RAM modules and installed just one RAM stick -> Same issue
-
Downgraded BIOS to version 4408 and left at BIOS defaults -> Same issue
It looks like the system likes eating the PCIe USB cards. I will try ASUS customer support tomorrow but I am not expecting much from that..
Could this be an IRQ conflict? What still baffles me is how the issue isnt resolved if the machine is shut off for say 30 secs, but is after it was off for 10 minutes. It would then usually boot up with all cards recognized again.. In the back of my mind I am imagining some hardware failure that depends on something capacitively charged that could explain such time-delay behaviour.. Any thoughts/other ideas?

RE: PCIe USB card (and PCIe bridge) disappear after host reboot
Okay, story continues:
- Had DVD SATA not plugged into the mainboard.
- System booted fine and PCIe devices got listed fine across reboots.
- Plugged DVD drive in to verify it breaks things (as explained above).
- Disconnected DVD SATA from mainboard again, and the PCIe card indeed stayed unlisted across reboots still (as explained before).
- I shut down the machine and left it without power for 21 minutes
- I power up the machine but it doesnt boot. Black screen remains. Error LED on mainboard for "CPU" is lit up indicating some boot issue with the CPU.. Interesting.
- I cut the power and start the machine again. It starts up in "safe mode" and forces me into bios by pressing F1. I exit the bios with no changes.
- Machine restarts and then continues to boot fine again into XCP as usual. All PCIe cards are detected normally again, also across reboots.
And, another find: Its not specific to the DVD drive. Going from 0 plugged in SATA devices to plugging in one HDD the same issue occurs. So it seems more like if a system device is added/changed it causes the issue..
Curious if anyone here can make anything from this? I am happy to replace the motherboard if that fixes the issue, but can we be sure what component is really faulty here? (motherboard/cpu/ram/pcie card?)

RE: PCIe USB card (and PCIe bridge) disappear after host reboot
Spent some more time troubleshooting. And made some interesting discoveries!
First I tried setting various things in the bios, like:
- Advanced->AMD CBS->Global c-state control: Was set to "auto", tried: "enabled" and "disabled"
- Advanced->AMD CBS->CPU common options->Local APIC mode: Was "x2APIC", tried: "compatibility", "xAPIC", "auto"
These changes didnt help anything though, the issue remained.
Also installed a new XCP NG on the 2nd M.2 in that server so I could test with the "normal" XCP NG against a fresh install. -> Same issue
Set power supply from "multi rail" to "single rail" -> Same issueToday I made the discovery. Plugging the DVD drive into the SATA port on the mainboard, that triggers one of the PCIe USB cards to not be recognized anymore, as explained in the original post above. Interestingly, if unplugging the DVD SATA from the mainboard after it caused the issue, that PCIe USB card still remains unlisted. If I leave the server like 1h powered down and then start it up (with DVD drive not connected to any SATA port) it appears the system will keep recognizing all PCIe cards. Very interesting..
So working config in this server is as such:
- 6 PCIe cards (as mentioned in first post above)
- 2x M.2 SSDs (1x 2 TB and 1x 4 TB) on the motherboard
- 4x SATA devices attached (3x HDDs 18TB 18TB and 20TB, 1x SSD 500GB)
If I plug in the DVD drive (which would be the 5th SATA device) it breaks things.
Any more ideas what may be going on/be behind this?

RE: PCIe USB card (and PCIe bridge) disappear after host reboot
@olivierlambert Hi, yes im running the latest BIOS version 5003 (released just 2023/10/31).
Any suggestions what kind of bios settings to look at in particular? I have a pretty much identical system (as far as motherboard+cpu+ram+ssds+pcie USB cards+pcie NIC go) and that one has not shown this behaviour so far. Bios version and settings in both systems I checked and should be pretty much identical I think. -
PCIe USB card (and PCIe bridge) disappear after host reboot
Hi,
I have an Asus X570-Pro with a Ryzen 9 5950X CPU. After a reboot of the machine one of my PCIe devices (always one of the USB PCIe cards) is no longer detected. Once gone, it stays gone across reboots. To fix it, it seems I usually need to remove a card, power up the server, power it down again and plug the card back in. It still will be gone again after the next reboot after that again.
I have the following cards installed in its 6 PCIe slots:
- 4 port USB card (running x1)
- 7 port USB card (running x1)
- 10Gbit network card (should be running x8)
- 7 port USB card (running x1)
- 7 port USB card (running x1)
- Nvidia Quadro K2200 GPU (should be running x8)
This is the lspci output when all cards are detected correctly:

What can be seen is that in the broken situation the following two devices are missing (so not just the PCIe USB card but also a device called "PCIe GPP Bridge"):

07:00.0 USB controller: Renesas Technology Corp. uPD720201 USB 3.0 Host Controller (rev 03)I am no expert, but maybe this is a useful clue if that PCIe bridge disappears at the same time as the USB PCIe card.. I've spent the whole day troubleshooting all kinds of different slot combinations and removing/adding/reseating cards, but unfortunately to no avail.
Any clues/help would be much appreciated!

RE: PCI Passthrough with both GPU and USB
Hi,
I stumbled across exactly the same issue that GPU and USB pcie cards would crash the VM if passed through together. It was already mentioned in an earlier reply that updating would fix the issue, and I just wanted to confirm that works for me as well. After running the following commands on my xcp-ng 8.2:yum update yum upgrade
everything works nicely now! Thanks!
