[Gluster-devel] replicate data between 2 servers and 1 client

[Alain Gonzalez]

glusterfs send me this error:

2009-02-12 10:00:23 E [xlator.c:117:xlator_set_type] libglusterfs/xlator:
dlopen(/usr/lib/glusterfs/1.3.7/xlator/cluster/ha.so):
/usr/lib/glusterfs/1.3.7/xlator/cluster/ha.so: cannot open shared object
file: No such file or directory

What packages should I install to get ha.so?

Thanks for your help. Forgive me for my bad English
