<![CDATA[Unable to create XOSTOR volume]]>Hi everyone,

I am attempting to create an XOSTOR volume on a newly created pool as part of a demonstration environment for evaluating a migration from VMware vSphere to XCP-ng. However, I have been unable to successfully create the XOSTOR volume. I have attached the relevant error log for reference.

All hosts in the pool are identical Dell R730 systems, fully patched, each equipped with fifteen 1TB drives connected through a Dell HBA330 controller. The only difference between the four hosts is the amount of installed RAM. Running fully patched XOA trial.

This is my first time attempting to create an XOSTOR volume, and the error message returned does not provide much detail beyond stating “unknown error from the peer.” I would appreciate any guidance on what might be causing this issue.

Thank you in advance. Looking forward to rolling this out!

I thought maybe I was using too many disks, so I've tried creating disk groups of 3-4 drives with the same issue.

I'm new to xcp-ng but it seems I have the same issue.
I have done some tests to resolve this (but failed) and if I remember, when i look at /var/log/audit.log in the first host of my cluster, I saw this error :

... [ failure: repodata/repomd.xml from xcp-ng-linstor: [Errno 256] No more mirrors to try. https://repo.vates.tech/xcp-ng/8/8.3/linstor/x86_64/repodata/repomd.xml: [Errno -1] repomd.xml signature could not be verified for xcp-ng-linstor ...

but installing manually xcp-ng-linstor with yum does not solve the issue.

PS : In your case, it seems you want more than 7 disks in your xostor and I think you need between 3 and 7 disks.

Can anyone help decipher what the issue is? I'm stuck on this trial deployment until I can get the storage configured. Thanks!

Are you on XOA trial and/or air gap environment ?
I remember seeing the -32000 error a while ago, but I don't remember why 🤔
