Re: [ovirt-users] Reclaim disk space of thin disks

Hi, seems not to work with FC Storage, I Zero filled the Disk with dd, removed the file and did a fstrim which told me it trimmed the right amount of space, But the disk Image stays full size.

Yes, if the underlying file system supports it (NFS, for example, might need to be 4.2 and above). Or can it be done by making a snapshot and clone the VM to a new one? Another suggestion: use the VDSM hooks for discard ('diskunmap') and run 'fstrim' from within the guest. Y.
