Ok, so, turns out this is because of the
thin-send-recvpackage I build from https://github.com/LINBIT/thin-send-recv/tree/masterI just swapped out the version I built for the last one I was able to get online to test, and it works.
The last version I was able to get from any repository before they went 403 was thin-send-recv-1.0.1-1.x86_64.rpm.txt, I was able to get this from https://piraeus.daocloud.io/linbit/rpms/7/x86_64/thin-send-recv-1.0.1-1.x86_64.rpm. FYI https://packages.linbit.com/yum/sles12-sp2/drbd-9.0/x86_64/Packages/ returns 403's too so no point in looking for it there if they have it hosted.
I built thin-send-recv-1.1.2-1.xcpng8.2.x86_64.rpm.txt using this doc I put together thin-send-recv.txt. But this package I built is resulting in the error posted previously.
So I am a bit at a loss, I want to be able to use velero for backing up pvs which are not managed by an operator with backup capabilities, but I do not want to be stuck with this old version I can not update.
Any advice would be greatly appreciated!

Ok great, I manually built 1.0.1, and it works just like the package I got online, that means that what I am doing is working and the build process is correct.
The bad new is there is a breaking change with v1.1.2, and I think I am potentially SOL.
I am going to build and test v1.1.0 and v1.1.1 to see which ones work. NVM v1.1.0 is also broken.So the change that breaks it is in here: https://github.com/LINBIT/thin-send-recv/compare/6b7c9002cd7716ff6ef93f5a5e8908032b81f853...e44f566ea0c975e2baa475868ebc176065a5b22d
v1.0.1 might just be the version that works with the version of linstor, and whenever that gets updated it might call for a newer version of thin-send-recv.

@ronan-a might take a look if he found a minute free (which is complicated right now
) -
@olivierlambert @Jonathon Unfortunately we don't maintain this package, so it's not available in our repositories, the simplest thing is that you address this problem directly to linbit. Maybe there is a regression or something else?

This post is deleted! -
I spoke with one of our developers. He said:
"When I search for
Device read short 40960 bytes remainingI only get results for XCP-ng/Citrix with LVM. So I think this is an issue with LVM on xcp-ng. One thing we changed between thin-send-recv 1.0.X and 1.1.X is the error handling, so now errors are properly propagated. So I would guess it was always broken but newer versions actually make the error visible."
Not sure if that helps, but if there is anything to relay I'm more than happy to pass it along.

@BHellman Appreciate the weigh in and the time from your dev.
Ok yeah I thought I was having a hallucination lol. v1.0.1 was 100% working when I installed it at time of my posting, and it was failing today. Restarting all the satellites and it works, assuming it will break again.
When it actually works, I can see the pvc in s3 remote
Here are a scatter of commands and outputs. In this I restarted the satellites, so it may be difficult to read but thought it would be better then nothing.
commands-and-outputs.txtxen01-linstor-Satellite.txt
xen02-linstor-Satellite.txt
xen03-linstor-Satellite.txt -
And now for something completely different lol.It's the same thingWe 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

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.

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.
-
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.

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
-
LINSTOR can be reach in NFS or iSCSI if I remember correctly. You question is more for LINSTOR than for XCP-ng
-
@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 --disklessSo the base idea is to use xcp-ng nodes for linstor-controllers/linstor-satellite and "storage" nodes as linstor-satellite only.
-
@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.
-
@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? -
@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.
-
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-BThe DotHills were 4 ports per controller, and the two controllers were configured as:
Management
iSCSI-A
iSCSI-B
SpareThe 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.

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