I think this is going to work. I cancelled a partial defrag and did another move attempt, and this time 5GB got moved! So I'm going to let the whole thing finish and try again and that will probably fix it. Interestingly I had to specify the -t option to get some big files to move, it wouldn't work without it (I'm doing "btrfs fi defrag -r -v /mymedia -t 500000000"). > > That's not good.

Oh yeah, it was definitely a problem with either the drives or the external enclosure, which was converting USB to SATA and mirroring the drives internally (it was a WD MyBook Mirror Edition). There was a problem with one of the drives and I replaced it, but before I did it screwed up some data. I think one drive kept trying to do a retry on a read and somehow the logic decided to just give me a "nearby" sector to satisfy the read (I can't really figure out how else 10 seconds of a random but "nearby" in alphabetical order MP3 could get stuck into the middle of another MP3). So I removed the entire enclosure and put them inside my case and decided I never wanted it to happen again so I converted to btrfs. :) Very happy it exists! -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
