When testing I killed the glusterfsd process (and it also occured after a reboot of the server) a few moments after, read/write operations to the mountpoint started failing with 'Transport endpoint is not connected'

after the node was restarted the system may recover, however this does not always happen.

The docs say afr is RAID1, normally RAID1 will continue to operate when a drive is lost.

Version: glusterfs-1.3.0-pre2.3
OS: debain4.0 (etch) with fuse libs from unstable
Appropriate Client Config Entries:
volume server1-raw
  type protocol/client
  option transport-type tcp/client # for TCP/IP transport
  option remote-host x.x.x.1 # IP address of the remote brick
  option remote-subvolume bricklocal # name of the remote volume
end-volume

Specification Add client feature and attach to remote subvolume of server1
volume server1-backup
  type protocol/client
  option transport-type tcp/client # for TCP/IP transport
  option remote-host x.x.x.2 # IP address of the remote brick
  option remote-subvolume brickbackup # name of the remote volume
end-volume
volume server1
  type cluster/afr
  subvolumes server1-raw server1-backup
  option replicate *:2
end-volume
... (duplicated for server2 thu 4) ...

volume bricks
  type cluster/unify
  subvolumes server1 server2 server3 server4

  option scheduler alu   # use the ALU scheduler
