[Gluster-users] "No space left on device" problem

[wenaideyu wenaideyu]

hi

  I took 4 servers for glusterfs, sev1 and sev 2 were used for replicate1,
sev3 and sev4 were usered for
replicate2, replicate1 and replicate2 were combined for nufa, there is
server.vol in every server:

server.vol

volume posix
  type storage/posix
  option directory /mnt/data1
end-volume

volume locks
  type features/locks
  subvolumes posix
end-volume

volume brick
  type performance/io-threads
  option thread-count 8
  subvolumes locks
end-volume

volume server
  type protocol/server
  option transport-type tcp
  option auth.addr.brick.allow *
  subvolumes brick
end-volume


client.vol in sev1
volume  sev1
  type protocol/client
  option transport-type tcp
  option remote-host sev1
  option remote-subvolume brick
end-volume

volume  sev2
 type protocol/client
 option transport-type tcp
 option remote-host sev2
 option remote-subvolume brick
end-volume

volume  sev3
 type protocol/client
 option transport-type tcp
 option remote-host sev3
 option remote-subvolume brick
end-volume

volume  sev4
 type protocol/client
 option transport-type tcp
 option remote-host sev4
 option remote-subvolume brick
end-volume

volume replicate1
  type cluster/replicate
  subvolumes sev1 sev2
end-volume

volume replicate2
  type cluster/replicate
  subvolumes sev3 sev4
end-volume

volume nufa
 type cluster/nufa
 option local-volume-name replicate1
 subvolumes replicate1 replicate3
end-volume

volume writebehind
  type performance/write-behind
  option page-size 128KB
  option cache-size 1MB
  subvolumes nufa
end-volume

volume cache
  type performance/io-cache
  option cache-size 512MB
  subvolumes writebehind
end-volume

every server has a disk mounted on /mnt/data1, the disk has a capability
with 40GB,
so the glusterfs's total capbility is 80GB,

client is in sev1, and mount the glusterfs on /mnt/data

now the problem is that: when the replicate1 is nearly fullfilled, for
expample when the
replicate1 is 50MB free, i copy a file A bigger than 50MB into /mnt/data,
file A will be
created on replicate1, while the replicate1 is fullfiled, the rest of file A
can not be
write on replicate2,and the log in sev1 or sev2 is that:

[posix.c:1736:posix_writev] posix: writev failed: No space left on device

anybody can help me??? thanks very much
