Its starting to really concering me. Every loop I get missing chunks and
under-goal files... We have production web server running on this and we
cannot afford to have unavailable files. When a file is unavailable this
means it's a lost sell. The numbers are getting higher. Maybe the load
is too high ?
We are having about 6 server with about 1 millions lookup per hours each
, 500k opens per hours and 70k read per hours.
We also have another mooseFS cluster with the same settings on different
machines and we have no under-goal files or missing files.
Thanks
check loop start time check loop end time files under-goal files
missing files chunks under-goal chunks missing chunks
