X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 15 Oct 2007 05:15:40 -0000 system A has these three partitions that I created in sysinstall, using the default sysinstall newfs values: /dev/aacd0s1e 465759710 434158260 3655868 99% /mount1 /dev/aacd1s1d 1891513834 1746678920 31344084 98% /mount2 /dev/aacd2s1d 2030137706 1801943816 228193890 89% /mount3 So, doing the math, the total space used of the three filesystems is: 3982780996 (roughly 4 TB) I just created a new filesystem on system B, where I used newfs on raw disk to create a SINGLE large >2TB partition. The newfs command I used was: newfs -i 32768 -U /dev/aacd1 I then used rsync to transfer ALL of the data from the old system to the new system. Now that I am done, and I have re-run rsync several times to be sure that all of the data is in place on the new system, the space used on the new system is: 3552249780 That's a difference of almost .5 TB ... and furthermore, I would think having less dense inodes would actually _increase_ the effective space that all those files take up, not _decrease_ it ... So is this expected ? Does it have something to do with moving the data from three partitions to one ? The bottom line is, I want to be SURE that all of the data is transferred before I scrap system A ... rsync is telling me all the data is there, because when I re-run it, nothing new gets transferred ... but I really want to "prove" it by looking at the total file size ... and I can't seem to do that currently.
