Title: Transfers window empty. Temp dir populated
Post by: Mithrandir.TheIstari on August 03, 2008, 01:47:53 AM

Hello guys.

A few days ago power went off at home and my Debian Lenny pc (aMule 2.2.1) was shutdown in the hard way. After that, when I open aMule I cannot see the transfers I had in progress.

I see the incoming/temp folder (xfs partition) and have all the .part, .part.met, and .bak files, however I cannot find the way to aMule take them again to restart downloading.

Any clue on how to get my downloads continue?

Thanks

xfs? Your files are probably 0 byte now and gone forever. If they are not 0 byte, then there should be a way to recover them.

If the .met and .bak are 0-size, the only solution you have is to know which file is each .part, start that download again, then overwrite the new .part with the old .part and pray aMule will rehash it.

For 7 downloads I have 3 0-sized met and met.bak files. I´m going try to identify them and redownload.

How to rescue the non 0-sized?

EXT3 would have handled this problem better?

It seems the shutdown make aMule to use (or recreate) the default config file. As I use personalized temp and incoming folders that's why I wasn't seeing the non-0-sized files. I arranged my config file and got the files.

For the 0-sized I was able to recover one of them. The other two were lost.

The filesystem question remains, though. Would EXT3 (or any other) have handled this issue better?

ext3 with ordered (default) or journal mode, yes. In writeback mode you might lose data, but maybe not to 0 byte as with xfs.

I'm no expert, but xfs (and jfs, which I use, too) are prone to data losses in case of a crash or power out. This is usually no problem as this happens only rarely and the higher performance should be worth it, but in higher risk environments I wouldn't use these file systems.

I have the same problem on my openSUSE 11.0. I have a soft raid 1 with 2 disks and a xfs partition for my /home dir and every time power goes out i lose many queued files and amule even switches back to its default config, which is really annoying.
Time to get a UPS or maybe switch back to reiserFS...
