zvol used apparently greater than volsize for sparse volume
...from home1
home1/home1mm01 readonly off default
home1/home1mm01 shareiscsi off default
home1/home1mm01 copies 1 default
home1/home1mm01 refreservation 0 default
Yet used (14902492672) * compresratio (11.20) = 166907917926
which is 3.6% larger than volsize.
Is this a bug or a feature for sparse volumes? If a feature, how
much larger than volsize/compressratio can the actual used
storage space grow? e.g., fixed amount overhead and/or
fixed percentage?
Thanks.
