That will cause qemu to ignore the live UNMAP SCSI comma= nds coming from the guest and not pass it on to the underlying storage.=0A= Note that this makes fstrim completely redundant, as the purpose of the c= ommand is to discard unused blocks under the given path.=0A= =0A= Redundant ? Useless you mean ? From my comprehension, the purpose to fstrim= is to send UNMAP SCSI on batch instead of mount -o discard that send them = synchronously.=0A= ------=_NextPartTM-000-bb13544b-1435-41ab-bb19-431fe0d6715d Content-Type: text/plain; name="InterScan_Disclaimer.txt" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="InterScan_Disclaimer.txt"
