Hi,

I'm trying to use unify to replace my NFS servers but i have some problems.
In my tests I also see about a quarter of the fiels that I see on NFS.
I also get the following errors on my glusterfsd.log:

I don't think I have any hardware problems as I can cat all the files
in my home directory without any problem.

I tried to reproduce the problem with a smaller setup without much
luck unfortunately.

Here is the client file:

volume tintoretto
  type protocol/client
  option transport-type tcp
  option remote-host tintoretto
  option remote-subvolume brick
end-volume

volume giotto
  type protocol/client
  option transport-type tcp
  option remote-host giotto
  option remote-subvolume brick
end-volume

volume michelangelo
  type protocol/client
  option transport-type tcp
  option remote-host michelangelo
  option remote-subvolume brick

volume donatello
  type protocol/client
  option transport-type tcp
  option remote-host donatello
  option remote-subvolume brick
end-volume

volume ns
  type protocol/client
  option transport-type tcp
  option remote-host tintoretto
  option remote-subvolume ns
end-volume

volume bricks
  type cluster/unify
  option namespace ns # this will not be storage child of unify.
  subvolumes tintoretto michelangelo giotto donatello
#  option self-heal foreground # foreground off # default is foreground
#  option self-heal background # foreground off # default is foreground
### ** Round Robin (RR) Scheduler **
  option scheduler rr
# A server is not used if it's free disk space drops below 15%.
  option scheduler.limits.min-free-disk 15% #%
end-volume

volume bricks-rs
  type features/filter
  option root-squashing enable
  subvolumes bricks
end-volume

volume iot
  type performance/io-threads
  subvolumes bricks-rs
  option thread-count 4
end-volume

volume wb
  type performance/write-behind
  subvolumes iot
  option flush-behind off    # default value is 'off'
  option window-size 2MB
  option aggregate-size 1MB # default value is 0
end-volume

### 'IO-Cache' translator is best used on client side when a filesystem has file
# which are not modified frequently but read several times. For example, while
# compiling a kernel, *.h files are read while compiling every *.c
file, in these
# case, io-cache translator comes very handy, as it keeps the whole
file content in
# the cache, and serves from the cache.
# One can provide the priority of the cache too.

volume ioc
  type performance/io-cache
  subvolumes wb
  option page-size 1MB      # 128KB is default
  option cache-size 64MB    # 32MB is default
  option cache-timeout 5 # 1second is default
  option priority *.c:2,*.h:1 # default is *:0
end-volume


### 'Read-Ahead' translator is best utilized on client side, as it prefetches
# the file contents when the first read() call is issued.
volume ra
  type performance/read-ahead
  subvolumes ioc
  option page-size 1MB         # default is 256KB
  option page-count 4          # default is 2
  option force-atime-update no # defalut is 'no'
end-volume
