Hello, I just hit a curious thing.
I use two identical (bough together) external usb 5Tb drives (as archives)
Fort whatever reason one was formatted EXR4 and the other kept as NTFS
I just made a rsync --delete from one to the other, verified they keep the exact same number of files.
The ext4 one have 915 Gb free, the other 687 Gb
wtf!!
Maybe due to the metadata organization, will be different on each.
is it possible to move such disk from ntfs to ext4 without reformatting all (and copying 4.5Tb data)?
Maybe a proprietary tool. I'm thinking of Partition Magic. Are they big files, like videos? You will save even more space by using XFS. On the contrary, if they are very small (1KB) you gain more with Reiserfs. Maybe with btrfs without snapshots. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
