Over the past week I have been testing 2.2.4 on saving to an external hard drive running ntfs. I have been using ntfs-3g v1.1120 and fuse v2.7.1. These are my experiences.

Well ktorrent does support full preallocation. I didn't run into any issues with that. The ntfs-3g driver also seems to fully support symlinking to an ext3 partition.

So far I have downloaded eight torrents ranging from 350MB to 7+GB. All the hash checks worked fine. All the files work properly. I have also been able to move torrents while downloading (using set download location) between partitions. I have also moved them while seeding. Again there seems to be no problems with that.

The problem I have been running into is slow speeds. Now this may be a problem with my laptop as I have been having issues with usb media. But the kttorrent log seems to be full with

Code: Select all

mmap failed : No such device

My dmesg however remains empty.

So I put this out there. Not as a bug report or asking for help... but just to let the community know the experiences I have had with it.

That is good to here.

Looking at the man page of mmap, I find this

ENODEV The underlying filesystem of the specified file does not support memory mapping

So ntfs-3g does not support mmap, but this is OK we will fallback to buffered mode when mmap fails.

but this is OK we will fallback to buffered mode when mmap fails.

Does it already do this, or is this something that is in svn or will be soon??

AFAIK it already does it.

It has done it from the start, seeing that this message could be annoying, maybe we should just automatically choose buffered mode when we see this a couple of times for a torrent.

That makes more sense. Because I had no idea what it was even about.
