Specifically, I want to share a file system (i.e. mount a common directory) on several CentOS5 and CentOS6 nodes. I don't think I can mount an RBD from more than one node, so what is my best bet? >> >> Mount an RBD on a file "head" and export it via NFS? >> >> I feel like that is the only sane choice, but wanted to ask in case I am missing something better. Your other options are re-exporting NFS or CIFS, or trying to use ceph-fuse. I recall using ceph-fuse on CentOS 6 personally and I've heard people talk about ceph-fuse on CentOS 5, though we don't currently actively test either. There, your biggest problem tends to be the 32-bit limitation; ceph inodes are 64-bit, and ceph-fuse really wants to run on a 64-bit machine. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
