Ouch! "903MB downloaded" but 68.84 GB of disk space?!?!?!

Hi All

Using 2.11 on Mac

Hi have a torrent downloading that is taking up 68.84 GB of disk space, yet only 903MB have been downloaded so far

Also just noticed 2.75 GB is being held by another torrent .... but it's only reporting 19mb of data?!

Is it normal for Transmission to reserve space like this for incomplete downloads?!

Pretty sure it is standard in most clients since it makes sure they can complete the download, without you needing to calculate how much you have left when adding more to that partition in any form.

Yes, Transmission allocates the full file to reduce fragmentation.

[tman]

Check the "preallocation": value in settings.json, I think 0 is not to allocate (allocate only when downloading the specific file) and 1 to allocate all space at the beginning.
My transmission does not allocate anything if not downloaded, I have the value set to 0.

1) He's on Mac. Mac doesn't use settings.json
2) 0 is preallocation = off (high chances of fragmentation), 1 = sparse (unsupported in HFS+ anyway), and 2 = full.

Wow! So that could explain why my file system (and transmission a little bit) is so sluggish ! I must try set to "2". Thanks !

What Filesystem are you using? Some FSs have preallocation that's as fast as the sparse method. (ext4)

Edit: Unselected and incomplete files also need to be completely allocated on Mac thanks to HFS+ not supporting sparse files. This will be improved when Ticket 532 is implemented.

How can I find ext type ? A ssh command ?
Edit: tried "fdisk -l /dev/sda1" but it just shows "linux", not the type. Googleing does not helped...
