Rehashing because st_nlink less than dentry maps

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello eveybody.
I'm experimenting glusterfs which seems very promising.

BUT i'm facing some problems.

I'm trying to setup some X11/nomchaine/nx servers, all accesing a large and global filesystem.

The system itself is on a local filesystem, but /home is a glusterfs.

Connection whith nx client hangs, and here are the errors on the client

2008-04-15 17:30:08 W [fuse-bridge.c:402:fuse_entry_cbk] glusterfs-fuse: 27570: (34) /comptes/dupont-y/.Xauthority => 8432041 Rehashing because st_nlink less than dentry maps 2008-04-15 17:30:09 W [fuse-bridge.c:681:fuse_fd_cbk] glusterfs-fuse: open() got EINTR

On server I got nothing special.


I'vre tried very recent version of glusterfs :

pulteney:~# glusterfs --version
glusterfs 1.3.8 built on Apr 11 2008 17:05:00
Repository revision: glusterfs--mainline--2.5--patch-739

and I simplified at maximum the config (without any performance enhancement)

server side :
##-----------------------

volume brick1
  type storage/posix
  option directory /GLUSTER/1
end-volume

##

volume brick2
  type storage/posix
  option directory /GLUSTER/2
end-volume

##

volume brick3
  type storage/posix
  option directory /GLUSTER/3
end-volume

##

volume brick4
  type storage/posix
  option directory /GLUSTER/4
end-volume


##
volume ns
  type storage/posix
  option directory /GLUSTER/NS/1
end-volume


##
volume ns2
  type storage/posix
  option directory /GLUSTER/NS/2
end-volume

volume server
  type protocol/server
  option transport-type tcp/server
  option auth.ip.brick1.allow XX
  option auth.ip.brick2.allow XX
  option auth.ip.ns.allow XX
  option auth.ip.brick3.allow YY
  option auth.ip.brick4.allow YY
  option auth.ip.ns2.allow YY
  option window-size 2097152
  subvolumes brick1 brick2 brick3 brick4 ns ns2
end-volume

## client side :


# file: /etc/glusterfs/glusterfs-client.vol

## 1er groupe.

volume remote1a
  type protocol/client
  option transport-type tcp/client
  option remote-host gluster1.univ-nantes.prive
#  option window-size 2097152
  option remote-subvolume brick3
end-volume

volume remote1b
  type protocol/client
  option transport-type tcp/client
  option remote-host gluster2.univ-nantes.prive
#  option window-size 2097152
  option remote-subvolume brick3
end-volume

volume mirror1
  type cluster/afr
  subvolumes remote1a remote1b
end-volume

#### 2eme groupe.

volume remote2a
  type protocol/client
  option transport-type tcp/client
  option remote-host gluster1.univ-nantes.prive
#  option window-size 2097152
  option remote-subvolume brick4
end-volume

volume remote2b
  type protocol/client
  option transport-type tcp/client
  option remote-host gluster3.univ-nantes.prive
#  option window-size 2097152
  option remote-subvolume brick3
end-volume

volume mirror2
  type cluster/afr
  subvolumes remote2a remote2b
end-volume


volume remote3a
  type protocol/client
  option transport-type tcp/client
  option remote-host gluster3.univ-nantes.prive
#  option window-size 2097152
  option remote-subvolume brick4
end-volume

volume remote3b
  type protocol/client
  option transport-type tcp/client
  option remote-host gluster2.univ-nantes.prive
#  option window-size 2097152
  option remote-subvolume brick4
end-volume

volume mirror3
  type cluster/afr
  subvolumes remote3a remote3b
end-volume

### Assemblage avec unify.


volume remote-ns
  type protocol/client
  option transport-type tcp/client
  option remote-host gluster1.univ-nantes.prive
  option remote-subvolume ns2
end-volume

volume unify0
  type cluster/unify
  option scheduler rr # round robin
  option namespace remote-ns
  subvolumes mirror1 mirror2 mirror3
end-volume
