Native Ceph RBD SM driver for XCP-ng
-
@olivierlambert you basically replied just after that I noticed that and deleted my message...
-
Nothing fruitful to add....
But...
Oooof....
This will be somewhat messy to clean up. I'm rooting for you guys though!!
-
There's some nice progress on @psafont's work regarding improved revert. I'm confident we'll get there
-
Hello,
Thanks for your work !
We have some hypervisors of tests at Gladhost, we can use them with pleasure to test your work on xcp-ng 8.3 !
Best regards

@benapetr Good news, seems like the latest version for SM will implement vdi_revert which should work nicely with Ceph RBD. The only thing now is to have the newer Ceph kernel drivers in XCP-ng since the current driver is very old... (v12 I believe, we're now at v20, soon v22)

Hello @Maelstrom96.
This should be possible in the future version of XCP-NG built on top of alma 9
-
It's more like "partially"/loosely based on Alma (10, not 9). And yes, the kernel will be far more recent, same for Xen and so on.

@olivierlambert I backported recent libceph/rbd/krb5 support to the xcp 8,3 kernel to support the new ceph authx aes256k method and include more rbd image features. I've added the rpms which install these newer versions as alt and extra modules and can be removed again as well. although I did run test on it I would suggest people to take caution and do not test in PROD

https://imirc.nl/xcpng/rbd-module-alt-1.0.0-1.xcpng8.3.x86_64.rpmIf anyone else is interested / has feedback please do let me know!
Kind regards
