Check the permissions on the directory where the file system is mounted. If only root can write to that directory, then that is likely why. You could either change those permissions to allow write access as needed or you could require that any writes to the OrangeFS file system by users other than root occur in a subdirectory that has appropriate permissions.
Hope that helps, Elaine From: [email protected] [mailto:[email protected]] On Behalf Of Ionescu, A.

However, pvfs2-mkdir and pvfs2-cp work fine and the files thus created can be removed with the regular rm command on the mounted volume. Note that I have been running everything as root. Both nodes run Centos 6.2 (Linux kernel version 2.6.32-220.el6.x86_64) and I chose --with-openib and --without-bm-tcp. Only the node01 is a metadata server and therefore, when mounting, I used the following command: #mount -t pvfs2 ib://node01:3335/pvfs2-fs /mnt/pvfs2 I would really appreciate your help on this issue and I'd be happy to provide any information you might need.
