Hi,

VM/CT images are thinly allocated on ceph.

so the image should expand as needed ??

 

[Spyder13337]

i have create several images .raw file and move them over to the Pool with ceph install on all nodes if i shrink the VM can they expand on there own is that possible on ceph or once it reaches it 100% drive space it dies

If you move disk you copy zeros for unallocated space.
Ensure discard is enabled on the VM vdisk setting and run inside the VM fstrim to release unused space.
