@Jonathon Ok, here's the solution, and the explanation:
First, just update
xcp-ng-release-linstor. This will update the repository file for linstor-related RPMs to make it point to a newer repository, located at a different place.Then updating the rest of the system will become possible again.

Unfortunately does not look like that works. Unless I am doing something wrong.

Some questions about XOSTOR
Storage between the servers is not shared as a large file system like Gluster. Right?
So for example, each 4 hosts has 2TB storage then the max HD space is 2TB (widely)
Is the NIC speed of the storage network important? Is 2x40G on each server for this overkill?
What software raid on the NVME disks is recommended?
/Christian
-
@Chr57 I'm no XOSTOR expert, but AFAIK the total available space will depend on the replication factor.
-
Storage between the servers is not shared as a large file system like Gluster. Right?
So for example, each 4 hosts has 2TB storage then the max HD space is 2TBAs @stormi mentioned, this depends on your replication factor. It works like this for your example:
Total Space = (No of Hosts x Storage ) / Replication Factor
(Assuming you have same storage on all nodes)Eg. replication factor is 2, then :
Total Space = (4 x 2)/2 = 4 TB
Note:
What you have to keep in mind though is it also depends on each SSD you have so say if you put 1.5 TB SSD & 0.5 TB SSD, then although you have 2TB on each node, but if you create a VM with 1TB space, you will not be able to create another VM with 1TB since there will not be enough contiguous space. What it means is that XOSTOR will not split the VM disk on two separate drives in case of JBOD.
In case of Raid 0 at bios level, you may be able to get away with this but Raid 0 is not recommended.Is the NIC speed of the storage network important? Is 2x40G on each server for this overkill?
The question is generic and it actually depends on your workload and SSD speed (Gen4 or Gen5 or if you have an old Gen1). At the outset 2x40G seems to be more than enough for most applications. If you have a an old Gen1 SSD or SATA SSD, then you might not even reach the full bandwidth in case of 2x40GB (practically speaking).
What software raid on the NVME disks is recommended?
For going production with Nvme SSDs, I would not recommend RAID at all ! JBOD would work just fine.(Assuming your are using generic applications)

Hello to you,
I am new to the XOSTOR solution,
I followed the instructions to build an SR XOSTOR, except that unfortunately I have been stuck for 2-3 weeks on an error when creating the SR, below is my error:
Error code: SR_BACKEND_FAILURE_5006
Error parameters: , LINSTOR SR creation error [opterr=Could not create SPxcp-sr-linstor_groupon nodeDEV-XCP02: The satellite does not support the device provider LVM],here is the command I run: xe sr-create type=linstor name-label=XOSTOR host-uuid=52c3a2bb-50a8-4700-a232-6e535e24d759 device-config:group-name=linstor_group device-config:redundancy=2 shared =true device-config:provisioning=thick
thank you in advance for your help, and this great project
-
Hi,
I am actually new to XOSTOR and I have very basic questions to begin with.
Does it support only Pools ? Can we attach such SR on many independent XCP-ng hosts?Thanks again for this incredible project.
-
Hi,
It works only at pool level, the only way have coordination between hosts and knowing which host have the lock on which VM. This is essential to avoid booting the same VM/disk at 2 different places without knowing, leading to data corruption.
-
@olivierlambert said in XOSTOR hyperconvergence preview:
- FINALLY YOU CAN CREATE THE SR:
Otherwise with thin provisioning:
xe sr-create type=linstor name-label=<SR_NAME> host-uuid=<MASTER_UUID> device-config:group-name=linstor_group/thin_device device-config:redundancy=<REDUNDANCY> shared=tru
Is this part of the command not needed?
device-config:hosts=XCP-01,XCP-02,XCP-xx - FINALLY YOU CAN CREATE THE SR:

question for @ronan-a
-
@fatek No. I removed this param, it's useless now.
-
@ronan-a Since XOSTOR is supposed to be stable now, I figured I would try it out with a new setup of 3 newly installed 8.2 nodes.
I used the CLI to deploy it. It all went well, and the SR was quickly ready. I was even able to migrate a disk to the Linstor SR and boot the VM. However, after rebooting the master, it seems like the SR doesn't want to allow any disk migration, and manual Scan are failing. I've tried unmounting/remounting the SR fully, restarting the toolstack, but nothing seems to help. The disk that was on Linstor is still accessible and the VM is able to boot.
Here is the error I'm getting:

Have you restarted the satellites?

@Maelstrom96 said in XOSTOR hyperconvergence preview:
However, after rebooting the master, it seems like the SR doesn't want to allow any disk migration, and manual Scan are failing.
What's the status of these commands on each host?
systemctl status linstor-controller systemctl status linstor-satellite systemctl status drbd-reactor mountpoint /var/lib/linstor drbdsetup events2Also please share your SMlog files.

Edit: Just as a sanity check, I tried to reboot the master instead of just restarting the toolstack, and the linstor SR seems to be working as expected again. The XOSTOR tab in XOA now populates (it just errored out before) and the SR scan now goes through.
Edit2: Was able to move a VDI, but then, the same exact error started to happen again. No idea why.

You lost quorum.
I would start looking at DRBD - that is the underlying part that isn't working at the moment. When I deployed this I wanted to understand the parts. Key to the Linstor layer - drbd stores the cluster state and membership.
I'd advise reading the DRBD docs as well as the Linstor docs to find the commands you need to stand this back up. I really don't advise using anything spinning for disk. SSD and NVMe is the ticket. You can make rust work but its terminally slow. I found 3TB disk was ok ( ~60MB/sec ) but 9.1 (10 ) TB were just awful at with 20-40MB/sec the best I saw. I removed all the XOSTOR stuff this week to maybe reinstall on some 4TB NVMe.
The upside of all that time learning drbd and linstor was helpful when I decided to use the Piraeus operator at the kubernetes level. Its basically all the same bits built from source on the nodes you deploy on and includes a CSI driver.
