The scenario:

CentOS release 5.2 (Final)


configuration (server & client) from:
glusterfs-volgen -n storage --transport ib-verbs storage01-ib:/storage

InfiniBand: Mellanox Technologies MT25204 [InfiniHost III Lx HCA]

mount command on client return:
glusterfs#storage-ib-verbs.vol on /storage type fuse


1. Copy from local disk to directory /storage  (glusterfs)

pv < CentOS-5.2-x86_64-bin-DVD.iso > /storage/file
4.29GB 0:00:10 [ 429MB/s] [=================================>] 100%

2. after that when a run any command to gluster storage, this fails whit the
next error:
ls /storage
ls: /storage: Transport endpoint is not connected

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              48G   11G   35G  23% /
/dev/sda3             171G  188M  162G   1% /data
tmpfs                 7.9G     0  7.9G   0% /dev/shm
df: `/storage': Transport endpoint is not connected

before a couple of minutes these commands works whell !!!

what is wrong with my configuration?

The storage node (glusterfs) is  a RAID 6 system of 18 HD, dual quad core
whit 32GB RAM.
The cliente node is too dual quad core system with 16GB RAM.

Thanks in advanced.
