@Maelstrom96 said in XOSTOR hyperconvergence preview:
What happened was that for some unknown reason, our /var/lib/linstor mount (xcp-persistent-database) became read only
There is already a protection against that: https://github.com/xcp-ng/sm/commit/55779a64593df9407f861c3132ab85863b4f7e46 (2021-10-21)
So I don't understand how it's possible to have a new time this issue. Without the log files I can't say what's the source of this issue, can you share them?
Did you launch a controller manually before having this problem or not? There is a daemon to automatically mount and start a controller:
minidrbdcluster. All actions related to the controllers must be executed by this program.Another idea, the problem can be related to: https://github.com/xcp-ng/sm/commit/a6385091370c6b358c7466944cc9b63f8c337c0d
But this commit should be present in the last release. -
@ronan-a Is there a way to easily check if the process is managed by the daemon and not a manual start? We might have some point restarted the controller manually.

Edit2 : Also, I don't believe that service would've actually caught what happened, since it was mounted first using RW, but seems like DRBD had an issue while the mount was active and changed it to RO. The controller service was still healthy and active, just impacted on DB writes.
-
@Maelstrom96 It's fine to restart the controller on the same host where it was running. But if you want to to move the controller on another host, just temporarily stop
minidrbdclusteron the host where the controller is running. Then you can restart it.The danger is to start a controller on a host where the shared database is not mounted in
/var/lib/linstor.To resume, if the database is mounted (check using
mountpoint /var/lib/linstor) and if there is a running controller: no issue.Edit2 : Also, I don't believe that service would've actually caught what happened, since it was mounted first using RW, but seems like DRBD had an issue while the mount was active and changed it to RO. The controller service was still healthy and active, just impacted on DB writes.
So if it's not related to a database mount, the system may have changed the mount point to read only for some reason yes, it's clearly not impossible.
Also, what logs would you like to have?
daemon.log, SMlog, kern.log, (and also drbd-kern.log if present)
-
@ronan-a I will copy those logs soon - Do you have a way I can provide you the logs off forum since it's a production systems?

Not sure what we're doing wrong - Attempted to add a new host to the linstor SR and it's failing. I've run the install command with the disks we want on the host, but when running the "addHost" function, it fails.

Does that mean that we can't add or remove hosts from linstor without unmounting all VDIs?
-
@Maelstrom96 No you can add a host with running VMs.
I suppose there is a small issue here... Please send me a new time your logs (SMlog of each host).
-
We were able to finally add our new #4 host to the linstor SR after killing all VMs with attached VDIs. However, we've hit a new bug that we're not sure how to fix.
Once we added the new host, we were curious to see if a live migration to it would work - It did not. It actually just resulted in the VM being in a zombie state and we had to manually destroy the domains on both the source and destination servers, and reset the power state of the VM.
That first bug most likely was caused by our custom linstor configuration that we use where we have setup another linstor node interface on each nodes, and changed their PrefNics. It wasn't applied to the new host so the drbd connection wouldn't have worked.

You're lucky, I just produced a fix yesterday to fix this kind of problem on pools with more than 3 machines: https://github.com/xcp-ng/sm/commit/f916647f44223206b24cf70d099637882c53fee8
Unfortunately, I can't release a new version right away, but I think this change can be applied to your pool.
In the worst case I'll see if I can release a new version without all the fixes in progress... -

You're lucky, I just produced a fix yesterday to fix this kind of problem on pools with more than 3 machines: https://github.com/xcp-ng/sm/commit/f916647f44223206b24cf70d099637882c53fee8
Unfortunately, I can't release a new version right away, but I think this change can be applied to your pool.
In the worst case I'll see if I can release a new version without all the fixes in progress...Thanks, that does look like it would fix the missing
drbd/by-res/volumes.Do you have an idea about the missing StoragePool for the new host that was added using
linstor-manager.addHost? I've checked the code and it seems like it might just provision the SP on sr.create?Also, I'm not sure how feasible it would be for SM but having a nightly-style build process for those cases seems like it would be really useful for hotfix testing.

Hello guys,
Awesome realisation, works like a charm! But security in low level. Anyone who wants break down disk cluster/HC storage does it. I installed and as I see Linstor Controller ports opened to whole world. Any solution have you to close external port (when management in global IP), and communicate through Storage Network? -
Hmm in theory I would say it should only listen on the management network (or the storage network, but not everything)
-
@ronan-a Any news on when the new version of linstor SM will be released? We're actually hard blocked by the behavior with 4 nodes right now so we can't move forward with a lot of other tests we want to do.
We also worked on doing a custom build of linstor-controller and linstor-satellite to allow support of Centos 7 with it's lack of
sedsid -wsupport, and we might want to see if we could get a satisfactory PR that could be merged into linstor-server master so that people using XCP-ng can also use linstor's built-in snapshot shipping. Since K8s linstor snapshotter uses that functionality to provide volume backups, it means that using K8s with linstor on XCP-ng is not really possible unless this is fixed.Would that be something that you guys could help us push to linstor?

If I remember correctly, this script is only here for adding the PBDs of the new host and configuring the services. If you want to add a new device, it is necessary to manually create a new VG LVM, and add it via a linstor command.
Also, I'm not sure how feasible it would be for SM but having a nightly-style build process for those cases seems like it would be really useful for hotfix testing.
The branch was in a bad state (many fixes to test, regressions, etc). I was able to clean all that up, it should be easier to do releases now.
Any news on when the new version of linstor SM will be released?
Today.

WARNING: I just pushed new packages (they should be available in our repo in few minutes) and I made an important change in the driver which requires manual intervention.
minidrbdclusteris no longer used to start the controller, instead we usedrbd-reactorwhich is more robust.
To update properly, you must:- Disable minidrbdcluster on each host:
systemctl disable --now minidrbdcluster. - Install new LINSTOR packages using
yum:
- blktap-3.37.4-1.0.1.0.linstor.1.xcpng8.2.x86_64.rpm
- xcp-ng-linstor-1.0-1.xcpng8.2.noarch.rpm
- xcp-ng-release-linstor-1.2-1.xcpng8.2.noarch.rpm
- http-nbd-transfer-1.2.0-1.xcpng8.2.x86_64.rpm
- sm-2.30.7-1.3.0.linstor.7.xcpng8.2.x86_64.rpm
- On each host, edit
/etc/drbd-reactor.d/sm-linstor.toml. (Note: it's probably necessary to create the folder/etc/drbd-reactor.d/with mkdir.) And add this content:
[[promoter]] [promoter.resources.xcp-persistent-database] start = [ "var-lib-linstor.service", "linstor-controller.service" ]- After that you can manually start drbd-reactor on each machine:
systemctl enable --now drbd-reactor.
You can reuse your SR again.
- Disable minidrbdcluster on each host:
-
@ronan-a Just to be sure: IF you install it from scratch you can still use the installation instructions from the top of this thread, correct?
-
@Swen Yes you can still use the installation script. I just changed a line to install the new blktap, so redownload it if necessary.
-
@ronan-a perfect, thx! Is this the new release Olivier was talking about? Can you provide some information when to expect the first stable release?
-
@ronan-a Just to be clear on what I have to do..
-
Diable minidrbdcluster on each host:
systemctl disable --now minidrbdclusterno issue here... -
Install new LINSTOR packages. How do we do that? Do we run the installer again by running:
wget https://gist.githubusercontent.com/Wescoeur/7bb568c0e09e796710b0ea966882fcac/raw/1707fbcfac22e662c2b80c14762f2c7d937e677c/gistfile1.txt -O install && chmod +x install
or
./install update
Or do I simply installed the new RPM without running the installer?
wget --no-check-certificate blktap-3.37.4-1.0.1.0.linstor.1.xcpng8.2.x86_64.rpm wget --no-check-certificate xcp-ng-linstor-1.0-1.xcpng8.2.noarch.rpm wget --no-check-certificate xcp-ng-release-linstor-1.2-1.xcpng8.2.noarch.rpm wget --no-check-certificate http-nbd-transfer-1.2.0-1.xcpng8.2.x86_64.rpm wget --no-check-certificate sm-2.30.7-1.3.0.linstor.7.xcpng8.2.x86_64.rpm yum install *.rpmWhere do we get this files from? what is the URL?
- On each host, edit /etc/drbd-reactor.d/sm-linstor.toml no problem here...
Can you please confirm which procedure to use for steps 2?
Thank you.
