@olivierlambert I've understood that part... what I am wondering is if I have 3 hosts in one data center and 3 hosts in another, and I have asked for redundancy of 3 copies, is there a way to ensure all three copies are never in the same data center all at the same time.
-
So I imagine a very low latency between the 2 DCs? One pool with 6 hosts total and 3 per DC right?
For now, there's no placement preference, we need to discuss with LINBIT about topology.
And if the 2x DCs are far each other, I would advice to get 2x pools and use 2x XOSTOR total
-
@olivierlambert Correct... these DCs are across a campus on private fiber so single digit milliseconds worst case. We've historically had vmware keep 3 data copies and make sure at least one is in a separate DC... that way, when a DC is lost, the HA VMs can restart on the remaining host pool successfully because they have their storage available still.
-
So you can create a pool across the 2x DCs no problem. We'll take a deeper look on telling where to replicate to avoid having everything on the same place.

This can be done using placement policies as outlined in the LINSTOR users guide. It will probably require a bit of extra work on XO to use those properties
-
Technically, you could use manual CLI call to do it until we expose it in XO
-
For those that might run across my questions here... there is a nice blog post at Linbit on how to span availability zones correctly to keep your data redundancy up:
https://linbit.com/blog/multi-az-replication-using-automatic-placement-rules-in-linstor/So CLI is doable
GUI would be nice in the future

@Jonathon I see no issue in this output, except that you enabled zabbix mirrors which might or might not play a role in your update issue.
-
@stormi If you open a support tunnel and give me the ID in a private chat, I'll have a quick look.

@stormi Message sent, thanks!

@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.

The problem was yum cache. If I did yum update right after

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?

@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
