@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?

fred974

@ronan-a Just to be clear on what I have to do..

Diable minidrbdcluster on each host: systemctl disable --now minidrbdcluster no 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 *.rpm

Where 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.

fred974

@ronan-a is that the correct URL?

If we don't have a new critical bug, normally in few weeks.

@fred974

You can update the packages just using yum if you already have the xcp-ng-linstor yum repo config. There is no reason to download manually the packages from koji.

fred974

@ronan-a ok,
I managed to install using yum

yum install blktap.x86_64
yum install xcp-ng-linstor.noarch
yum install xcp-ng-release-linstor.noarch
yum install http-nbd-transfer.x86_64

But I cannot find sm-2.30.7-1.3.0.linstor.7.xcpng8.2.x86_64.rpm.
Is it yum install sm-core-libs.noarch ?

ronan-a

@fred974 What's the output of yum update sm?

Is it normal that the XOSTOR SR is still visible in XO?

@fred974 And rpm -qa | grep sm? Because the sm LINSTOR package update is in our repo. So I suppose you already installed it using koji URLs.

@fred974 I just repaired your pool, there was a small error in the conf that I gave in my previous post.

Fingers crossed!

Swen

@ronan-a: After doing the installation from scratch with new installed xcp-ng hosts, all uptodate, I need to do a repair (via xcp-ng center) of the SR after doing the xe sr-create, because the SR is in state: Broken and the pool-master is in state: Unplugged.

I am not really sure waht xcp-ng center is doing when I click repair, but it works.

I can reproduce this issue, it happens every installation.

regards,
Swen

olivierlambert

I don't remember if sr-create is also pluging the PBD by default

Repair is just a xe pbd-plug IIRC.

Swen

@olivierlambert it looks like sr-create is doing it, because on all other nodes the SR is attached, only on pool-master (or maybe the node you do the sr-create from) the pdb-plug does not work.

olivierlambert

What's the error message when you try to plug it?

Swen

@olivierlambert I need to me more clear about this: When doing the sr-create for the linstor storage no error is shown, but the pbd will not be plugged at the pool-master. On every other host in the cluster it works automatically. After doing a pdb-plug for the pool-master the SR will be plugged. No error is shown at all.

olivierlambert

Okay I see, thanks

Swen

Is there an easy way to map the linstor resource volume to the virtual disk on xcp-ng? When doing linstor volume list I get a Resource name back from linstor like this:

xcp-volume-23d07d99-9990-4046-8e7d-020bd61c1883

The last part looks like an uuid to me, but I am unable to find this uuid when using some xe commands.
