Hi,

This means your master encountered a write error while trying to save 
data to a changelog file. This might mean any kind of error: during 
open, write, fsync or close. Do you have enough space in your metadata 
directory (usually "/var/lib/mfs", but check your config)? Is the hdd in 
your master server working properly? Are there any generic (kernel) 
errors surrounding this message in your logs? Are you using the latest 
version of MooseFS?
