@olivierlambert With (experimental) CephFS driver added in 8.2.0. Reading the documentation

WARNING

This way of using Ceph requires installing ceph-common inside dom0 from outside the official XCP-ng repositories. It is reported to be working by some users, but isn't recommended officially (see Additional packages). You will also need to be **careful about system updates and upgrades.**

are there any plans to put ceph-common into the official XCP-ng repositories to make updates less scary?

I have been testing this for almost 8 months now. First with only one or two VMs, now with about 8-10 smaller VMs. The ceph cluster itself is running as 3 VMs(themself not stored on CephFS) with SATA-controllers passedthoughed on 3 different hosts.

This has been working great with the exception of in situations when the XCP-ng hosts are unable to reach the ceph cluster. At one time the ceph nodes had crashed(my fault) but I was unable to restart them because all VM operations were blocked taking forever without ever suceeding eventhough the ceph nodes them selfes are not stored on the inaccessable SR. To me it seems the XCP-ng hosts are endlessly trying to connect never timing out which makes them non-responsive.

    feat(self-signed): improve compat with OpenSSL 3
    
    `-key -` appears to no longer be supported, generating the key in the same step works better.
    
    It's still compatible with OpenSSL 1.

@julien-f same error. Running Xo from sources(have not checked the version yet)
