This files are MySQL database files. Tables contains only text so they compress well. But, if I copy some uncompressable file, for example some video than everything is ok, no error message, copy is successfull. I also tried mounting without compression (without compress-force=lzo) and in this case no error is reported. So it seems it's something with compression ? I'll try rebooting with ignore_loglevel parameter. >> >> It's the same error if I try to copy for ex. with midnight commander. > > I have the same kernel version, the same mount options, and use the same cp -a on a 5.3GB file and cannot reproduce your results. > > > Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
