[ovirt-users] local on host storage domain full, how to clean up

Hello, I have a local based storage domain that has got full, so that it is now inactive and virtual machines that are on it are paused (vm paused due to lack of storage space). Any advice on how to clean up, eventually deleting some of them? # df -h /2t_2 Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_2t_2-2t_2 1.8T 1.7T 0 100% /2t_2 [root@ovirt01 fdf9546c-68fa-42c9-8a10-78ef3ee534b8]# Is there any easy way to map disk-to-vm of directories inside /2t_2/images/dbf9611d-9090-42d6-81e0-58105bc20011/images/ so that I can "sacrifice" some VMs deleting the corresponding disks' directories, to be able at least to activate the storage domain again and make a cleaner check? Or any other suggestions? I'm not able to expand it. It is not directly managed by me and I suppose too much storage over-provisioning has been done. Thanks in advance. Gianluca
