Hi everyone, I was trying the new send/receive feature today but can''t make it work. These are the commands I was using: btrfs subvol snap -r /mnt/data1/@downloads/ /mnt/data1/snapshots/testsnap btrfs send /mnt/data1/snapshots/testsnap | btrfs receive /mnt/data1/snapshots/testreceive/ This command never finishes. A ''ls /mnt/data1/snapshots/testreceive/ '' never

The goal is to detect when drives start to get an increased error rate, when drives should be replaced soon. Therefore statistic counters are added that count IO errors (read, write and flush). Additionally, the software detected errors like checksum errors and corrupted blocks are counted. An ioctl interface is added to get the device statistic counters. A second ioctl is added to atomically get

Sigh. In the previously sent v2 patch the mail 1/4 exceeded the archaic 100,000 chars limit of vger.kernel.org (no complains from checkpatch.pl though).

Hi, I am maintaining a port of rsync (https://github.com/perlundq/yajsync) which is GPL:ed of course. The main purpose of the project is to provide a Java API library for the rsync protocol. It would therefore be really nice to be able to use LGPL as the license. But in order to do so I would first have to get a list of all the individual contributors to rsync and then be able to contact them

...head IO priority. Another fact which is no big surprise is that the overall data throughput of SSDs does not improve from the modified IO priority. The only effect on SSDs is that it is now possible to control the amount of IO time slice spent for scrub.

A few months ago, my btrfs storage array became corrupted because of a power failure. A while ago, I made this thread to try and resolve the problem. (http://www.digipedia.pl/usenet/thread/11904/15955/) You can find detailed information about the problem in the previous thread, but I am happy to provide any other details. It didn''t really go anywhere in the way of solving my problem. The
