datanode03 is the newest brick the bricks had gotten pretty full, which I think might be part of the issue: - datanode01 /dev/sda1 51T 48T 3.3T 94% /mnt/data - datanode02 /dev/sda1 51T 48T 3.4T 94% /mnt/data - datanode03 /dev/md0 128T 4.6T 123T 4% /mnt/data
each of the bricks are on a completely separate disk from the OS I'll shoot you the log files offline :) Thanks!
