About Unity import FS size

Hi all,

I try Unity file import  for SMB only.

When i check fs size after initial copy, the fs size are different to source VNX.

Why different it ?

    Is fs_dedupe turned on on the source, or are there any tree quotas? 

    do an fs_dedupe -l on the source VNX.  That could potentially affect how big the filesystem is on the target, assuming automatic creation.

    Perhaps its due to an underlying block size difference with UFS64 compared to UXFS.  That's just a guess of course, I'm sure someone with more insight here probably already knows the definitive answer.

    you need to look at details and file sizes

    one reason could be different size of file system metadata like inode size, superblock

    esp. with very small file systems yours
