[Gluster-users] gluster as openvz backend

[Xabier Elkano]

Hi,

I want to use gluster as storage backend for  OpenVZ containsers, but in
some of my containers I get errors like "doesn't exist and can't be
created: File exists". In this case when Apache tries to start inside
the container:

# apachectl -t
Syntax error on line 4 of /etc/apache2/mods-enabled/fastcgi.conf:
FastCgiIpcDir /var/lib/apache2/fastcgi: doesn't exist and can't be
created: File exists

I am using a replicated distributed volume with 4 nodes.  Each node is
acting as a client and as a server node. I just created the volume,
started and mounted with gluster native client.

The gluster versions I am using:

ii  glusterfs-client                 3.4.1-1                      
amd64        clustered file-system (client package)
ii  glusterfs-common                 3.4.1-1                      
amd64        GlusterFS common libraries and translator modules
ii  glusterfs-server                 3.4.1-1                      
amd64        clustered file-system (server package)

when I run apache command I can see these messages in the brick log:
