It uses raid6 on 11 1TB discs, using a chunk size of 32 kB. The filesystem is 88% full. The discs are on a 3ware 9650SE controller. The array has a set of backup "snapshots" with hard links created using the rsync --link-dest feature. We also used --sparse when doing the rsyncs. We have snapshots for a set of user directories, one for each day. The message occured while rsync was writing to the array (creating the snapshots) and it was being read by rsync or a tar to tar pipe to a second btrfs array.
