~~And now for something completely different lol.~~ It's the same thing

We have a new xcp-ng cluster that we would like to migrate everything to. Not migrating k8s clusters, creating new ones on a new RKE2 rancher. So to migrate the applications it would simplify things if I could move pvc's over.

Command that fails, same if I add --target-storage-pool xcp-sr-linstor_group_thin_device

I am curious if anyone else can replicate this, as it is just attempting to move a resource between two xostor clusters? If it is just me I can continue troubleshooting, otherwise it would be nice to know it is an exercise in futility.

But I am well aware that the release a few days ago has everyone swamped and this can wait, would just be awesome to know as it would change migration plans.

https://linbit.com/drbd-user-guide/linstor-guide-1_0-en/#s-linstor-snapshots-shipping

thin-send-recv is needed to ship data when using LVM thin-provisioned volumes

Yeah this seems to be for any type of shipping, s3 or otherwise.

Jonathon

So, did more testing. Looks like thin_send_recv is not the problem, but maybe socat.
I am able to manually migrate resource between XOSTOR (linstor) cluster using thin_send_recv. I have encluded all steps below so that it can be replicated.

And we know socat is used, cause it complains if it is not there.

Migrating using only thin_send_recv works.

Jonathon

The reason that it may be socat, is because the commands fail when I try using it, as instructed by https://github.com/LINBIT/thin-send-recv

[13:03 ovbh-pprod-xen11 ~]# thin_send linstor_group/pvc-12aca72c-d94a-4c09-8102-0a6646906f8d_00000_s_test 2>/dev/null | zstd | socat STDIN TCP:10.2.0.10:4321
2024/10/28 13:04:59 socat[25701] E write(5, 0x55da36101da0, 8192): Broken pipe
...
[13:03 ovbh-pprod-xen01 ~]# socat TCP-LISTEN:4321 STDOUT | zstd -d | thin_recv linstor_group/pvc-12aca72c-d94a-4c09-8102-0a6646906f8d_00000 2>/dev/null
2024/10/28 13:04:59 socat[27039] E read(1, 0x560ef6ff4350, 8192): Bad file descriptor

And the same thing happens if I exclude zstd from both commands.

Hi!

I'm looking for new storage cluster for XCP-ng, because ceph RBD performance is very poor.
The main quetion now - is it possible to build XOSTOR (linstore) cluster separatly from xcp-ng and connect it over ethernet?
No inforamtion about such scenario in this article.
So I would like to have "compute" claster of xcp-ng nodes with fast local NVMe disks + and dedicated storage cluster with big amount of HDDs connected vie ethernet.

And second question is about scaling.
How this storage cluster could be scaled? Is it possible to add storage nodes online without interrupting clients (VMs)?

Thank you

olivierlambert

LINSTOR can be reach in NFS or iSCSI if I remember correctly. You question is more for LINSTOR than for XCP-ng

splastunov

@olivierlambert NFS and iSCSI have single point of failure. Yes, it is possible to deploy multipath iSCSI, but it is to complicated. I like CEPH RBD because it does not have single point of failure.
So I'm looking for something similar.

From my point of vew XOSTOR is good idea, but in some cases there is no need to use all nodes as xcp-ng hosts. For example you do not need large amount of RAM and fast modern CPU for storage cluster nodes.
I think the best solution in my case will be to deploy XOSTOR controller in xcp-ng cluster connected to separate storage cluster.

At first glance, I assume that it should be possible to connect storage cluster to xcp-ng with this command
linstor resource create node1 test1 --diskless

So the base idea is to use xcp-ng nodes for linstor-controllers/linstor-satellite and "storage" nodes as linstor-satellite only.

Mark C

@splastunov / all.

Just on multipath iSCSI. I had this running for years with separate switches running the 'A side' and 'B side' multipath networks between the iSCSI dot hill's resilient and redundant controllers.

Once you have it configured, it is incredibly solid for what is a very budget solution. It just takes a bit of careful planning up front to make sure you wire up in a way that is properly resilient. Plus reliable monitoring to make sure that you notice when one of the resilient elements fails.

We had a number of switch power supply failures over the 10 year period that were completely transparent to the services running on the connected XCP-NG and XenServer hosts.

Similarly we were able to do a full DotHill controller replacement without any downtime after one of the two controllers failed.

We also replaced the hypervisor hardware a number of times over the lifetime of the platform.

splastunov

@Mark-C Thank you!
Could you tell please how you scale your storage with iSCSI? What hardware/software are you using for storage? Is it possible to add storage nodes on fly or you have to deploy new storag cluster every time when you grow?

Mark C

@splastunov The DotHill certainly wasn't great for scaling out, because of the age of the firmware and the old-school treatment of the disk arrays.

We did deploy several disk expansion trays that were part populated at purchase as some level of expansion, and operated most of the array as a single underlying pool, which was then split up into iSCSI presented volumes.

So the limitations of the DotHill controllers and firmware we were using didn't address the storage pool scaling issue that CEPH / GPFS / etal are designed to.

However, some of the newer filer heads that treat their entire available disk array as a consolidated pool and support iSCSI would have that scalability, whilst keeping the hypervisor side relatively straight-forward.

CEPH etal are also in a much more mature place than they were back in the early 2010s too, so if I was doing it again, maybe we would go for a solution architecture based around that. Or XOSTOR, of course!

My intent was to present an iSCSI setup instance as something we found relatively bomb-proof, and post-initial configuration, relatively easy to scale. We provisioned 24 port A and B side network switches with jumbo frame support to give us the scalability to add further pools of hypervisors or storage, as required.

Mark C

The typical hypervisor node was provisioned with at least 4 network ports, but most had 8 to allow trunking/resilience for every connection:

Management + live migration (Isolated)
World (Trunk)
iSCSI-A
iSCSI-B

The DotHills were 4 ports per controller, and the two controllers were configured as:

Management
iSCSI-A
iSCSI-B
Spare

The iSCSI-A and iSCSI-B were simple web-managed procurves with 24 ports each.

We had this scaled to 12 hypervisor nodes in 3 pools, all running off the same underlying dothill (dual redundant controller) hardware. We had provisioned some local SSD storage in each hypervisor for any nodes that were struggling for IOPs but ultimately never needed that.

OK we have debugged and improved this process, so including it here if it helps anyone else.

How to migrate resources between XOSTOR (linstor) clusters. This also works with piraeus-operator, which we use for k8s.

Need to yeet errors on both ends of command or it will fail.

This is the same setup process for replica-1 or replica-3. For replica-3 can target new-xostor-server-01 each time, for replica-1 be sure to spread them out right.

Replica-3 Setup

Explanation

thin_send to new-xostor-server-01, will need to run commands to force sync of data to replicas.

Last week I stood up two XCP-ng hosts with LINSTOR without issue.

This week I am standing up a third XCP-ng host and encounter a show stopping error when I try to install LINSTOR:

Error: Package: xcp-ng-linstor-1.1-3.xcpng8.2.noarch (xcp-ng-linstor)

...
Failed to install LINSTOR package: xcp-ng-linstor.

This third host is 100% identical in hardware to the first two hosts. Fresh from-scratch new install of XCP-ng. Here is an output of commands and their results on the third host:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
Failed to install LINSTOR package: xcp-ng-linstor.

It seems the sm* package(s) are missing ? I don't know what to do.

Edit 2024-11-17 1702 CST: yum install xcp-ng-release-linstor indicates xcp-ng-release-linstor is already installed and latest version.
