@TheiLLeniumStudios In this case, if DRBD is completely stuck, you can reboot your hosts. There is probably a lock or processes that have a lock on them.
-
@AudleyElwine Thank you for your feedbacks, I will update the script to handle the journal cases.

@ronan-a 2 of the nodes broke after restarting. I just kept getting the blinking cursor at the top left of the screen for hours. I'm going to have to reprovision all the nodes again sadly
-
Hey @ronan-a ,
What should I do to lower the chance of something in the past installation of xostor to affect my new installation?
lsblkis still showing the linstor volumes,vgsis also showinglinstor_group.
Will awipefs -afbe enough? Or is the "Destroying SR" button in XOA is enough? -
@AudleyElwine The PVs/VGs are kept after a
SR.destroycall but it's totally safe to reuse them for a new installation. The content of/var/lib/linstoris not removed after a destroy call, but it's normally not used because the linstor database is shared between hosts using a DRBD volume and mounted in this directory by the running controller. So you don't have manual steps to execute here.Of course if you want to reuse your disks for another thing,
wipefsis nice for that. -
@TheiLLeniumStudios There are always a solution to repair nodes, what's the output of
linstor --controllers=<HOST_IPS> node list?(Use a comma separated values for HOST_IPS.)

We just hit a weird issue that we managed to fix, but wasn't really clear at first what was wrong, and might be a good idea for you guys to add some type of healthcheck / error handling to catch this and fix it.
What happened was that for some unknown reason, our
/var/lib/linstormount (xcp-persistent-database) became read only, but everything kinda kept working-ish, but some stuff would randomly fail, like attempting to delete a ressource. Upon looking at the logs, saw this :Error message: The database is read only; SQL statement: UPDATE SEC_ACL_MAP SET ACCESS_TYPE = ? WHERE OBJECT_PATH = ? AND ROLE_NAME = ? [90097-197]We did a quick write test on the mount
/var/lib/linstorand saw that it was indeed in RO mode. We also noticed that the last update time on the db file was 2 days ago.Unmounting the mount and remounting it had the controller start back again, but the first time, some nodes were missing from the node list, so we restarted the linstor-controller service again and everything is now up and healthy.
-
I think we have a relatively important number of updates coming, fixing various potential bugs
Stay tuned! -
@olivierlambert any eta for the next beta release? Looking forward to test it.
-
Very soon

@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... -

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?
