Lost access to all servers

@fred974 If you can yes.
Send me the code using the chat. -
@ronan-a Thank you very much for helping fixing my pool
-
@fred974
It would be great, if you could write down some lines about the issue and how it could get fixed -
@KPS The DRBD volume of the LINSTOR database was not created by the driver. We just restarted few services + the hosts to fix that. Unfortunately, we have no explanation for what could have happened. So unfortunately I don't have much more interesting information to give. However if a person finds himself again in this situation, I can assist him in order to see if we can obtain more interesting logs.

This post is deleted! -
@ronan-a I will let you and the community know If I run into this problem again. I just find out that we had one of the NFS server that kept rebooting around the same time so I do wonder if it could have contribute to the issue if the hosts couldn't connect to it or not. I am not advanced enough to know if there is any corelation.

I may be having a similar issue to the one you helped @fred974 with last month. One (xcp-ng3) of the three hosts on my lab environment dropped out of the SR in the past day or so. I believe it may have coincided with a failed live migration to that host and/or a forced reboot of the host after that failed migration. Here's what I am seeing on the affected host:
[09:14 xcp-ng3 ~]# linstor node list Error: Unable to connect to linstor://localhost:3370: [Errno 99] Cannot assign requested address [09:14 xcp-ng3 ~]# drbdadm status xcp-persistent-database role:Secondary disk:UpToDate quorum:no xcp-ng1 connection:StandAlone xcp-ng2 connection:StandAloneThe other two hosts, xcp-ng1 and xcp-ng2, are still operating without issue. XO sees xcp-ng3 and does not throw any errors unless I attempt any action that utilizes the SR (makes sense). It seems apparent that the linstor controller is not running, as any linstor command results in the connection error above. Thoughts? Any other logs you need?
FWIW, I'd normally just wipe the host and reinstall, but I wanted to bring it to your attention in case there's any value to the project.

I think that might be interesting for @ronan-a indeed
-
To make matters more interesting, my primary host (xcp-ng1) running XO crashed due to overheating. (I just love the fun curveballs my lab environment throws me!
) When I powered that machine back up, I received the same "Unable to connect to linstor://localhost:3370" error as above on xcp-ng1 and of course the XOSTOR SR was not operating with nodes 1 & 3 offline.After some cursory poking around, I rebooted xcp-ng1 and lo and behold... my XOSTOR SR was fully restored for all three nodes!
Part of this is my ignorance on how the underlying elements of XOSTOR work, so I'm going to throw out some ideas here that may or may not be true. Feel free to correct / educate me!
When I forced a reboot of xcp-ng3, the XOSTOR (LINSTOR?) controller did not automatically rejoin the xcp-ng3 node into the SR for whatever reason when it came back online. Then when xcp-ng1 powered off unexpectedly, the controller (which I believe was running on xcp-ng1 - again I'm not fully sure how this functionality works when distributed across the cluster) again did not resume when that machine powered back on. After a controlled, graceful reboot of xcp-ng1, the controller started and synced back up with all 3 nodes. Does this make sense or seem plausible?
Any logs that would be valuable?Edit: One additional detail that I left out: when xcp-ng1 came back online, running 'drbdadm status' resulted in this message: "No currently configured DRBD found." After the graceful reboot, all was working properly again.

@johannes Hello, with a little delay
, is everything working in your pool now? There might be a useful log in /var/log/linstor-controller/ -
@ronan-a My pool is mostly working now, though I'm still seeing some quirks. I believe the problems I've seen thus far is due to the hardware instability of one of my hosts, as noted before. While frustrating, it has given me the opportunity to work through some host and SR recovery processes. That's the silver lining.
The main issue that I'm still seeing is when I attempt to load a specific stopped VM on a specific host (xcp-ng3). The VM will fail to start and throw this error:
SR_BACKEND_FAILURE_46(, The VDI is not available [opterr=VDI a9d53abc-f492-4826-b659-744ee87d4d94 not detached cleanly], )This VM will start without issue on the other two hosts. XO is not showing any other issues with this VM and is not showing any orphaned VDIs.
I am also seeing these errors in the /var/log/linstor-controller directory:
Host xcp-ng1:

Let me know if you need to see anything else! Thank you!
