[Pvfs2-users] "Permission denied" issue

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,

Subject: [Pvfs2-users] "Permission denied" issue
Dear Pvfs2 users,
I've just installed Orangefs 2.8.5 on two nodes of a small cluster and I'm
facing the following problem: I keep getting "Permission denied" errors
whenever I try to create a new file or directory on the virtual volume.
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.
