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.

Thank you very much. I really appreciate you fixing this for me

@Swen said in XOSTOR hyperconvergence preview:

@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?

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

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

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

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.

Swen

@ronan-a: I am playing around with xcp-ng, linstor and Cloudstack. Sometimes when I create a new VM I run into this error: The VDI is not available
CS is trying it again after this error automatically and than it works and the new VM is starting. CS is using a template which is also on the linstor SR to create new VMs.
I attached the SMlog of the host.

It's just a PBD plug call I suppose. Can you share your logs please?

There is a tool installed by our RPMs to do that
For example on my host:

linstor-kv-tool -u xostor-2 -g xcp-sr-linstor_group_thin_device --dump-volumes -n xcp/volume
{

  "7ca7b184-ec9e-40bd-addc-082483f8e420/not-exists": "0", 
  "7ca7b184-ec9e-40bd-addc-082483f8e420/volume-name": "xcp-volume-12571cf9-1c3b-4ee9-8f93-f4d2f7ea6bd8"

@ronan-a sure, which logs exactly do you need?
