The ceph pools create success, but happen timeout when create VM on it.

[CrystalCat]

I create a CEPH pool with one monitor, one mgr, and 4 OSDs
All OSD using the Samsung SSDs.
The Ceph Pool is using the default configuration. It creates success and shows in the web interfaces,the demoPools
Here is the server's summary:



However, when I try to create the VM on it, it can not succeed, it will timeout when creating RBD.
The error is:


TASK ERROR: unable to create VM 100 - rbd error: 'storage-demopool'-locked command timed out - aborting

Much more, the web interfaces will also freeze. It will time out for any opterate such as will the ceph's status.

The PVE version is 7.0-8
I also try to creating a RBD through cli, but it also will hang in the SSH.

Read documentation. You can't use default ceph config with 1 node.
