I’ve live migrated RBD images of our VMs (with ext4 FS) through our Proxmox PVE cluster from one pool to anther and now it seems those device are no longer so sparse as before, ie. pool usage has grown to almost sum of full image sizes, wondering if there’s a way to untrim RBD images to become more sparse again? fstrim doesn’t seem to be supported on the virtual devices in the VMs. TIA /Steffen _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
