July 9, 201510 yr I need to move the files from one disk to another for the purpose of reformatting a disk from btrfs to xfs. I want to make sure I do this the right way. So I plan to use rsync (just starting to us that vs CP) but its gots LOTs of options. When considering what unRaid does with files, is there a specific set of options I should use? I'm considering the following... rsync -avWz --progress /mnt/disk5/movies/ /mnt disk2/movies/ -a for recursing through the directories -v for verbose info (just while I get familiar with what its doing...) -z to compress data during transfer (several TB, so gain a bit of efficiency?) -W to move only whole files Better set of options to use? Thanks for the wisdom!
July 10, 201510 yr Author So just playing around and tried a couple different structures. Start with -avWz - VERY slow...I guess the compression is costly...probably only useful for xfer across the internet... root@HunterNAS:/mnt# rsync -avWz --progress /mnt/disk5/movies/ /mnt/disk2/movies/ sending incremental file list created directory /mnt/disk2/movies ./ Celtic Woman/ Celtic Woman/Celtic Woman - Jesu Joy of Man's...

July 10, 201510 yr Whenever I have questions about RSYNC I just read the man page and that usually helps. A few things. 1) The -a flag is generally what you want, but it does a lot more then just recurrusion. 2) Some users will find -X as helpful as well since they have information in extended attributes that they want to keep. 3) I do not recomend -zon your first rsycn run, it's better on recuring runs (after the first) when you are only doing the difference and not transfering GB or TB of data. Also I think it really is ment for transfers accorss a network instead of local copying.
July 10, 201510 yr There are a few rsync recommendations at the bottom of the Converting Drives from ReiserFS to XFS section of the Upgrade guide. Credit for them goes to WeeboTech.
