@ronan-a said in XOSTOR hyperconvergence preview:

Yes, you can. Please take a look to: https://linbit.com/drbd-user-guide/linstor-guide-1_0-en/#s-managing_network_interface_cards
To get the storage pool name, execute this command in your pool:

OK - so to set up this XOSTOR SR I would first

xe sr-create type=linstor name-label=XOSTOR01 host-uuid=xxx device-config:hosts=<XCPNG Host Names> ...etc...

to create the Linstor storage-pool. Then

linstor storage-pool list

to get the name the pool. Then on each node found in device-config:hosts=<XCPNG Host Names> run the following command:

linstor storage-pool set-property <host/node_name> <pool_name> PrefNic <nic_name>

where nic_name is the name of the Linstor interface created for the specific NIC.

As promised I have done some more "organised" testing, with a brand new cluster set up to test XOSTOR. Early simple tests seemed to be OK and I can create, restart, snapshot, move and delete VMs with no problem.

But then after putting a VM under load for an hour and then restarting it I am seeing the same weird behaviour I saw previously with XOSTOR.

Firstly, the VM took far longer than expected to shutdown. Then trying to restart the VM fails.

Let me know if you want me to provide logs or any specific testing.

The linstore volume for this VM appears to be OK (by the way I hope eventually we have an easy way to match up VMs to Linstore volumes)

This VM is set up the same way as several other VMs I have running on another cluster but using SRs on NFS mounts.

This is with latest XCP-ng version, all servers patched and up-to-date.

yum update

No packages marked for update

@geoffbland Thank you for your tests.

Could you send me the other logs (/var/log/SMlog + kern.log + drbd-kern.log please)? Also check if the LVM volumes are reachable with linstor resource list. Also, you can check with lvs command on each host. EIO error is not a nice error to observe.

@ronan-a The volumes are reachable on all nodes:

Volumes appear to be OK on 2 hosts and not present on the third - although with rep set as 2 I think that is expected?

No lines

Although when running the lvs command on each host I am getting a lot of warnings about DRDB volumes - these seem to be volumes that were previously deleted but not cleaned up fully:

We've been trying to re-setup linstor on our new pool, and it seems to be working this time. However, when attempting to enable pool HA, it's not working correctly with this error :


[16:36 ovbh-pprod-xen10 ~]# xe pool-ha-enable heartbeat-sr-uuids=a8b860a9-5246-0dd2-8b7f-4806604f219a
This operation cannot be performed because this VDI could not be properly attached to the VM.
vdi: 5ca46fd4-c315-46c9-8272-5192118e33a9 (Statefile for HA)

@Maelstrom96 said in XOSTOR hyperconvergence preview:

However, when attempting to enable pool HA, it's not working correctly with this error :

After reviewing the code, it seems like there's a critical file /etc/xensource/xhad.conf that is not created when setting up HA and LinstorSR.py expects it. Hopefully that information can help

Hello,

Have been using XOSTOR for a week. On Xen Orchestra the free space and used space calculations are off.

173.86/446.91 = 39%, the green lines at the bottom do not look like they are filling up 39%

Also the free/used space in xen are not accurate, when I do linstor storage-pool list i see a 40GiB used space while Xen Orchestra says 173.86GiB. Note I'm running delta backups on the vms so not sure if this is the cause.

should I only focus on linstor storage-pool list and ignore the numbers on Xen orchestra?

Thank you,

@geoffbland said in XOSTOR hyperconvergence preview:

Volumes appear to be OK on 2 hosts and not present on the third - although with rep set as 2 I think that is expected?

Yes, this volume is a diskless, you can have a diskless DRBD in /dev, but no LVM volume is used.

Although when running the lvs command on each host I am getting a lot of warnings about DRDB volumes - these seem to be volumes that were previously deleted but not cleaned up fully:

I will confirm that.

Yes the computation is incorrect. I fixed our method for the next beta update, the replication count was used in the formula, it's completely wrong. You should have (446.91 - 403.47) GiB instead of 173.86 GiB (so (446.91 - 403.47) * 4).

Not exactly the problem. I fixed the issue but not released yet.
You can edit /opt/xensource/sm/LinstorSR.py and replace get_host_address function definition on each host:

def get_host_addresses(session):
    addresses = []
    hosts = session.xenapi.host.get_all_records()
    # Instead of:
    # for record in hosts:
    # use the new line below:
    for record in hosts.itervalues():
        addresses.append(record['address'])
    return addresses

Must be fixed after that. I think I will release a new RPM in ~1-2 weeks.

Hi,

I restarted one of my vms but I couldint get it up due to this error.

SR_BACKEND_FAILURE_46(, The VDI is not available [opterr=Plugin linstor-manager failed], )

I really dont know why, I tried my best to debug it but I dont know from where to start.

I did a grep -r {VID-UUID} /var/log, hopefully there is something here we can debug.

xostor-log-vdi.txt

Note it was working normally before August 1 3pm in the logs, I cant migrate the data from this XOSTOR to local SR due to another error but I have a backup of the vms.

I'm on the latest version of the xostor; ./xostor --update-only says im on the latest version.

Thank you

AudleyElwine

I exported a snapshot for the vm so the data is safe. It is just now I'm worried about restarting other nodes on the cluster.

I'm happy to debug it I just need some gudiance as I havent done anything special to the VM since it is creation, so not sure why the VDI error appeared.

@ronan-a In my latest test I created a new VM with multiple disks on XOSTOR. This worked OK and I was able to run and access all the disks.

However I then tried to remove this VM. After a long period of nothing happening (other than the spinning icon on the remove button) I get a "operation timed out" error and the VM is now shown as paused again.

If I try to delete again, the same thing happens.

All the volumes used by this VM still exist on linstor and linstor shows no errors.

Now when I try to create any new VM, this now also fails with the following error:

Note /dev/drbd1031 does not exist in /dev/drdb or as a volume.

How do I remove the test VM? How to fix the issue with creating new VMs?

I have been attempting to use xostore with k8s linstor csi for storage class

on the host on port 3370, it returns the following via via http

API Documentation
As LINBIT SDS subscriber you can install the UI by running apt install linstor-gui or dnf install linstor-gui.

Using this guide https://linbit.com/blog/linstor-csi-plugin-for-kubernetes/
This is what it is outputting. The port is accessible with telnet from inside the k8s cluster.

Thoughts?

Ah, I had the configuration wrong.

@ronan-a is off this week, but he'll come back next week!

@olivierlambert
Not a problem! I am 99% it is an issue with the CSI.

I am making progress, the CSI is trying to use k8s nodename, and has no idea what the hostname which is running the VM.

Jonathon

OK I figured it out! I made an init container that gets a manually created node label for the node the pod is running on. This value is the bare metal host for that k8s node. The init contianer then takes that value and makes a script wrapper and then calls linstor-csi with the correct values. After making these changes all the linstor csi containers are running with no errors.

Current problem comes from deploying and using storage class. Started with a basic one that failed, and noticed I did not know what the correct storage_pool_name name was, so went to http://IP:3370/v1/nodes/NODE/storage-pools and http://IP:3370/v1/nodes/NODE to get information.

Still troubleshooting, but wanted to provide info.

@AudleyElwine It seems a volume is still open but should be removed by the driver. You can check if a process has a fd on it using (on each host!):
cat /sys/kernel/debug/drbd/resources/xcp-volume-38e34dc1-8947-4b3d-af49-fbc5393c7069/volumes/0/openers.

Maybe a tapdisk instance or another process. Also can you send me the related SMlog file please?

ronan-a

@ronan-a said in XOSTOR hyperconvergence preview:

@geoffbland Thank you for your tests.
Could you send me the other logs (/var/log/SMlog + kern.log + drbd-kern.log please)? Also check if the LVM volumes are reachable with linstor resource list. Also, you can check with lvs command on each host. EIO error is not a nice error to observe.

So after analysis, I will patch the driver to log using DRBD openers file instead of lsof because there is probably a process that prevents tapdisk from opening the volume.

@geoffbland said in XOSTOR hyperconvergence preview:

Note /dev/drbd1031 does not exist in /dev/drdb or as a volume.

Regarding this specific issue if you have this resource in the LINSTOR DB, it's really weird. So can you upload the logs please? (SMlog + linstor files).

How do I remove the test VM? How to fix the issue with creating new VMs?

You can forget the VDI to remove the VM. If you can't remove properly it, you can use drbdsetup (detach/del-minor) to force destroy the DRBD volume.
Do you always have this issue when you create new VMs?
