[Gluster-users] Problem running Gluterfs over Infiniband

[Vlad Popa]

Dear List,

We  have lots of issues  running Glusterfs over Infiniband.  The client 
can mount the share, but when trying to access it  by ls, df,  touch du 
or any other  kind  the client hosts freeze the accessing shell and 
reboot is hardly possible.

OS:  CentOS 6.0 64 bit on i7  2600k machines
Version: GlusterFS 3.2.2, also found  in lower 3.2.1
Kernel Version 2.6.32
IB Stack and kernel moduls taken and built  from OFED /Open Fabrics (1.5.3)

/IP over IB works, I can ping ober Ib between the maschines,

Gluster System complains though  about RDMA errors...

IB Cards used: Mellanox  (kernel module mthca) dual port, 40GBps
one port per card only configured, used and  plugged on.
