@stormi
what's the status of the xfs driver? Are you expecting that to be removed/deprecated as well?

stormi

No, it's still there and still working but not officially supported.

New leaf coalesce logic using dynamic limits

I have backported patches from sm's master branch, that implement a new, smarter, logic for leaf coalescing.

Just update your 8.1 beta, restart the toolstack, and that should be it.

Those interested in the patches, see https://github.com/xcp-ng-rpms/sm/commit/ed1a55d727846cf5777c8258e6a8f3b068e8a35b (python code).

All my SRs are using the ext4 driver.

So I just need to export the VMs, (to a NAS for example), destroy the SR, and recreate the SR, then import the VMs?

I guess I’ll need to use XCP Center for this since I use XO community running on the SR that needs to be destroyed/recreated in a Debian VM.

Did anyone try VM export/import to see how much the performance has been improved?
More interesting would be if someone tried it with 10G or making backups with XOA.

When will the final version of XCP-ng 8.1.0. be available?

olivierlambert

RC should be there pretty soon. https://github.com/xcp-ng/xcp/issues/328

stormi created this issue in xcp-ng/xcp

closed XCP-ng 8.1 (meta issue) #328

Biggen

I’ll wait till 8.1 drops before I mess with changing SR storage types.

That kernel update is already available on 8.1 indeed, through yum update.

Not yet but I'd be really grateful to anyone who could benchmark this!

stormi

So, the main remaining development before RC is an updated installer to allow it to boot the alternate kernel in cases where the main kernel has issues. And also an option to boot with only 2G of RAM to workaround Ryzen APU "black screen" issues.

last week I installed a new server XCP-ng 8.1. But the filesystem is still Ext3. (by the way XO connects without problem but you need XCP-ng Center Development build to access)
Today I will install a new server, what should I do to get ext4 in the filesystem?
Thanks

olivierlambert

What do you mean? SR file system or root filesystem?

The Local Storage for VM.

I don't think you should trust XCP-ng Center on this. What do you think @borzel?

Check the output of mount instead.

onur

here is the output. So I assume ext4 should be default when selecting EXT on the setup.

It's ok, the SR is mounted as ext4 so this means it was created as ext4.

great thank you very much @stormi . As you suspected, XCP-ng Center shows wrong format (I guess here is a bug for XCP-ng center devs)
