@gb-123 said in XOSTOR hyperconvergence preview:
Are there any other packages in xcp-ng requiring python2 ?
Probably yes for few packages.
Would it be advisable to change default python to python3 (by adding alias in bashrc) ?
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.
-
Any idea why I am getting :
Error: Unable to connect to linstor://localhost:3370: [Errno 99] Cannot assign requested addressI installed linstor with replication as 2 and the VM is running fine. I am executing this command from dom0 of Pool Master.
-
@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.

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.

@Maelstrom96 We must update our documentation for that, This will probably require executing commands manually during an upgrade.
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 addresslinstor node interface list host1 gives me
host2 | NetInterface | IP | Port | EncryptionType + StltCon | default | 10.10.10.11 | 3366 | PLAINI 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

@limezest Are you sure that you only have one linstor controller running?
What's the output oflinstor resource list? Same formountpoint /var/lib/linstoron each host.Note: it's not a surprise to have this error:
Cannot assign requested address.
You must specifylinstor --controllers=<ips> <cmd>to execute a command from any host. -
@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. -
@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 mountpointOn node 2, the current controller node, I see:
/var/lib/linstor is a mountpointCurrently, 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:

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?[/edit2]

Hi team,
I'm currently testing xostor on a three nodes xcp-8.2.1 pool
Before adding any new vm, i replaced a node (xcp-hc3)
Since everything seems to be ok, i've added two vms.
But I think that a diskless resource is missing for "xcp-persistent-database"
Is there a way to resolve this situation ?[10:23 xcp-hc1 ~]# linstor resource list

I am getting :
WARNING: Pool zeroing and 1.00 MiB large chunk size slows down thin provisioning. WARNING: Consider disabling zeroing (-Zn) or using smaller chunk size (<512.00 KiB).How do I change Chunk Size and/or zeroing ?
Can this be done 'on the fly' (without loosing data) ?

This post is deleted! -
This thread has grown quite large and has a lot of information in it. Is there an official documentation chapter on XOSTOR available anywhere?
-
For now it's within this thread
Feel free to tell us what's missing in the first post! -
@BHellman The first post has a FAQ that I update each time I meet users with a common/recurring problem.
-
Thanks for the replies. My issues are currently with the GUI so I don't know if that applies here. This is all from the GUI, so please let me know if that's outside the scope of this post and I can post elsewhere.
One issue is upon creating a new XOSTOR SR, the packages are installed, however the SR creation fails due to one of the package, sm-rawhba, that needs updating. You have to apply patched through the GUI then reboot the node, or execute "xe-restart-toolstack" on each node. You can then go back and create a new SR, but only after wiping the disks that you originally tried to create the SR on; vgremove and pvremove.
I'm planning on doing some more testing, please let me know if GUI issues are appropriate to post here.

@BHellman It's fine to post simple issues in this thread. For complex problems a ticket is probably better.
One issue is upon creating a new XOSTOR SR, the packages are installed, however the SR creation fails due to one of the package, sm-rawhba, that needs updating.
Not totally that, sm-rawhba is added to the list because the UI installs a modified version of sm with LINSTOR support.
The real issue is that xe-toolstack-restart is not called during the initial setup, a method is missing in our updater plugin to check if a package is present or not, I will add this method for the XOA team. -
I'm not sure what the expected behavior is but....
I have xcp1, xcp2, xcp3 as hosts in my XOSTOR pool, using an XOSTOR repository. I had a VM running on xcp2, unplugged the power from it and left it uplugged for about 5 minutes. The VM remained "running" according to XOA, however it wasn't.
What is the expected behavior when this happens and how do you go about recovering from a temporarily failed/powered off node?
My expectation was that my vm would move to xcp1 (where there is a replica) and start, then outdate xcp2. I have "auto start" enabled under advanced on the VM.
