Sometimes when you have block based storage (FC, iSCSI) and you have a disk configured as thin provisioned, it could happen if heavy and/or rapid I/O and LVM resize operations don't satisfy timing needed If this is your case and you think you need enough sustained I/O in one VM you should configure its related disk as preallocated.
