Could not find enough space to create new chunk. Try clearing a few gigabytes of space, or defragging. about ntfs2btrfs HOT 7 OPEN

To all interested parties: to me 4% free space was enough to complete the conversion.
But maybe it depends on the type of files stored or other things.

Were you able to resolve this? I ran into the same issue on a 4 TB drive with over 500 GB of free space, I think that should be enough to convert the drive, no?

from ntfs2btrfs.

It needs contiguous space - I'm guessing you've got lots of part-allocated chunks. What does btrfs fi usage say?

Edit: Disregard that, I was getting confused. Have you got a lot of compressed files?

from ntfs2btrfs.

No, the drive isn't compressed at all... It contains a lot of Steam Games, and some Windows Apps that I really don't care about...

Not sure what is the right answer but for a EXT4 to BTRFS conversion 4% of free space was enough.
So, for my 500 GB NTFS partition i'll try 20 GB.
Once the next test is completed i'll report back.
ETA tomorrow evening :)

There's really no point in logging it with Red Hat, all they're going to do is send it back to me...
