@rtjdamen said in CBT: the thread to centralize your feedback:

are u able to spin up a test xoa based on stable? Maybe u can check if it does work in that version?

I'm already on stable channel

@olivierlambert @florent

I still have error, even after disabled CBT and purge snapshot.

"stream has ended with not enough data (actual: 446, expected: 512)"

It's a production VM, for a customer. What can I do quickly ?

Ticket #7729749

Thanks !

@olivierlambert

I can't test on latest channel, because long backup job are running?

Hi,

Same error here, Current version: 5.98.1

I disabled purge data option, but I still had error.

I opened a support ticket #7729749

Hello,

A simple question, should I backup my XOA VM? If yes, what are the recommendations?

Thanks !

@olivierlambert nice !

Ticket#7727235

Thanks !

Thanks @olivierlambert

I'm available to install patch on my installation if you want, and if it's possible.

in my case, even if I restart the jobs in error, the error vdi_in_use persists

I followed the advice above, restarted all my hosts one by one, I still have errors

What I have to do ?

Hi,

Same here, I updated XOA to 5.98 and I have this error

"can't create a stream from a metadata VDI, fall back to a base" on some VM

I have an active support contract.

Here the detailed log

In a perfect world, self-service users should be able to manage ACLs on their VMs and show backup tab on VM.

Hello, I need your help with Xen Orchestra. I have created a Self Service and associated a user group (GR_01). This user group independently manages resources (creation, deletion, etc.). The users of GR_01 want to delegate some operations (console access, reboot, etc.) to other users (GR_02).

I do not want to define these users as administrators because my instance is shared.

How can I do this?

Thank you for your help!

@john-c You've right, thanks for precisions.

However, thin provisioning on iSCSI is a real blocking thing for me, and I'm sure that I'm not alone

Will SMAPIv3 enable thin provisioning on iSCSI SRs?

Hello @olivierlambert ,

I am joining this topic as I have a few questions about SMAPIv3:

• Will it allow provisioning of VDIs larger than 2TB?

• Will it enable thin provisioning on iSCSI SRs?

Currently, the blockers I encounter are related to my iSCSI storage. This is a major differentiating factor compared to other vendors, and resolving these blockers would significantly increase your market share.

Thanks !

Hello,

I would like to implement the following backup/replication policy:

Replication of VMs every 6 hours on my second site

Backup of VMs every night at 10 PM, with retention of backups as follows:

• Retention of the last 7 days

• Retention of the last 4 weekends

• Retention of the last 12 month-ends

What do you recommend?

Thank you for your help!

@olivierlambert Thanks !

@olivierlambert

Thanks Olivier, if I accept the risk, how can I upgrade from 8.2 to 8.3 beta ?

Hello everyone,

I am setting up a shared infrastructure for a client, and they are asking me to enable vTPM on the self-service. I read this feature requires XCPNG 8.3. When will XCPNG 8.3 be publicly available? Is there an easy workaround in the meantime?

Thank you!

@olivierlambert

OK thanks!

@olivierlambert

Thanks

Is there a way to use cloud-init with self service?
