XOSTOR hyperconvergence preview

@gb-123 are you using XOA or XO from sources?
If from sources the issue might come from having a different openssl when creating the sdn-controller certificates.
You can either try with an XOA or generate manually your certificates.

Using XO from sources. I just turned on "Over-ride certificates" and reinstalled the whole XO virtual machine. Seems to work fine now.

My only problem was that why it suddenly stopped working when I installed Linstore as installing Linstor should not impact upon this. So thats why I reported this on this thread.

BenjiReis

@gb-123 I see thanks

Just bad timing imho because Linstor doesn't touch this part of the host and the openssl issue is more probably coming from the env when you run your XO.

anyway, glad it's working now!

@ronan-a

Any idea why I am getting the error while running the linstor command ?

Thanks

ronan-a

@gb-123 What command and error exactly?

@Maelstrom96 said in XOSTOR hyperconvergence preview:

Is there a procedure on how we can update our current 8.2 XCP-ng cluster to 8.3? My undertanding is that if I update the host using the ISO, it will effectively wipe all changes that were made to DOM0, including the linstor/sm-linstor packages.

Any input on this @ronan-a?

@ronan-a is in holidays for the next 2 weeks

However, I can answer: I'm currently using XOSTOR on a test cluster running on a fresh 8.3 and it works Can't tell for the upgrade though.

I was referring to the our earlier conversation :

@gb-123 said in XOSTOR hyperconvergence preview:

@ronan-a

running linstor command on both hosts gives the following error :

Traceback (most recent call last):
File "/usr/bin/linstor", line 21, in <module>
import linstor_client_main
ImportError: No module named linstor_client_main

@ronan-a said in XOSTOR hyperconvergence preview:

Regarding this error, can you say me what's your XCP-ng version? And what's the output of: yum list installed | grep -i linstor?

@ronan-a said in XOSTOR hyperconvergence preview:

Do you have a XCP-ng 8.3? And did you run the beta installation script on it?

I installed XCP-ng 8.3 beta from ISO and then applied all the patches that were available. To install linstor, I followed the 1st Post of this topic.

ronan-a

@gb-123 If you run LINSTOR on 8.3 (FYI, linstor packages on this version are considered unstable), you must call the linstor command like that:

> python3 /usr/bin/linstor

By default python2 is called and is not compatible with this version of LINSTOR:

> python2 /usr/bin/linstor resource list
Traceback (most recent call last):
  File "/usr/bin/linstor", line 21, in <module>
    import linstor_client_main
ImportError: No module named linstor_client_main

ronan-a

@Maelstrom96 We must update our documentation for that, This will probably require executing commands manually during an upgrade.

gb.123

@ronan-a

Are there any other packages in xcp-ng requiring python2 ?
Would it be advisable to change default python to python3 (by adding alias in bashrc) ?
Or do you think I should create a script which in-turn runs python3 command only for linstor ?

PS: By executing :

python3 /usr/bin/linstor

Result :

Error: Unable to connect to linstor://localhost:3370: [Errno 99] Cannot assign requested address

Although through XO, I can see the VM on Linstor SR running fine,

Probably yes for few packages.

I don't recommend to do that.

Or do you think I should create a script which in-turn runs python3 command only for linstor ?

It's probably the best solution for the moment. Our ideal goal would obviously to only have Python 3:

But currently XCP-ng 8.3 is still in development.
And there are still things to check before thinking about globally changing the default Python interpreter.

@ronan-a

Any idea why I am getting :

Error: Unable to connect to linstor://localhost:3370: [Errno 99] Cannot assign requested address

I installed linstor with replication as 2 and the VM is running fine. I am executing this command from dom0 of Pool Master.

Swen

@gb-123 pool master does not need to be linstor controller. Try this command on the other hosts. It will only work on the node which is the linstor controller.

gb.123

@Swen

Thanks so much. It seems that the controller Is running on Node 2.

Btw, is there any way to control the node on which controller is installed (without loosing the data)? I remember installing on Node 1 first and then on Node 2. But it seems that Node 2 is actually running the controller.

I know the above is a noob question, but I just wanted to be sure if the linstor controller actually moves to another node when one is not available.

Any news on that? We're still pretty much blocked until that's figured out.

Also, any news on when it will be officially released?

I have a 3 node cluster in my lab running 8.2.1 with thin provisioned LVM on SATA SSDs.

I changed the 10G management interfaces from being untagged to being being VLAN tagged and I did an emergency network reset following the changeover.
Each node only has one 10G interface which is used for all management, vm and storage traffic.

Following the network reset, the cluster did not automatically recover, so I restarted my three nodes.

Now the cluster is up and the nodes claim to be connected to the XOSTOR SR, but I cannot take snapshots, clone VMs, and some VMs fail to start with the following error:

SR_BACKEND_FAILURE_1200(, Empty dev path for 19f26a13-a09e-4c38-8219-b0b6b2d4dc26, but definition "seems" to exist, )

Any troubleshooting guidance is appreciated. Thanks in advance.

[edit1]
I am only able to run linstor commands such as 'linstor node list' on the node that is currently the linstor controller.

If I try linstor node list (or any linstor command) on the satellite nodes, i get the error:

Error: Unable to connect to linstor://localhost:3370: [Errno 99] Cannot assign requested address

linstor node interface list host1 gives me

host2       |   NetInterface     | IP            | Port   | EncryptionType
+ StltCon   |   default          | 10.10.10.11   | 3366   | PLAIN

I am able to use 'linstor-kv-tool' to find the linstor volume that maps to each of my virtual disk images, but only on the controller.

linstor-controller.service is running on host 2
linstror-satellite.service is running on hosts 0 and 1, but i don't see any process listening on 3366 from netstat -tulpn
[/edit1]

ronan-a

@limezest Are you sure that you only have one linstor controller running?
What's the output of linstor resource list? Same for mountpoint /var/lib/linstor on each host.

Note: it's not a surprise to have this error: Cannot assign requested address.
You must specify linstor --controllers=<ips> <cmd> to execute a command from any host.

ronan-a

@Maelstrom96 The XCP-ng 8.3 LINSTOR version is not often updated, and we are totally focused on the stable 8.2 version.
As a reminder XCP-ng 8.3 is still in beta, so we can't write now a documentation to update LINSTOR between these versions because we still have important issues to fix and improvements to add that can impact and/or invalidate a migration process.

limezest

@ronan-a Thanks for the reply.

Node2 is currently the controller. All three nodes are currently running the satellite and monitor service.

On nodes 0 and 1 (the satellite nodes) I see:

/var/lib/linstor is not a mountpoint

On node 2, the current controller node, I see:

/var/lib/linstor is a mountpoint

Currently, some VDI are accessible, others are not.

For example, when i try to start my XOA VM I get the following error. I get the same error no matter which node i try to start the VM on:

XOSTOR: POST_ATTACH_SCAN_FAILED","2","Failed to scan SR 7c0374c1-17d4-a52b-7c2a-a5ca74e1db66 after attaching, error The SR is not available [opterr=Database is not mounted]

There is no entry for this UUID beginning in 7c03 in the output of the linstor-kv-tool

More interesting results:

One of my VMs has multiple vdi. The OS disk loads fine. The second disk can only be mounted read-only via mount -o ro,noload /dev/xvdb /mnt/example

The second disk xcp-volume-5283a6e0... has status "unknown" from linstor resource list

I can make VMs that have no disks.
I cannot create new VMs with VDIs on our XOSTOR SR.
I cannot create XOSTOR-hosted disks on existing VMs.
I cannot make snapshots.
I cannot revert to earlier snapshots
I get a not particularly helpful error from xcp-ng center: The attempt to create a VDI failed. Any recommendations about where I should look for related logs?
