Hi All, Have been trying to set up ocfs2 on a machine that will act as a SAN. O/S used is Ubuntu 7.10 for both host and node. Mounting the shared ocfs2 storage via iscsi target+initiator on the node and as a local mount on the host. Everything installed perfectly. Modules are loaded and services started. So far so good :) Problem comes in when booting the node and mounting the block device there. It then starts giving an error on the host stating "Another node is heartbeating in our slot". The error number given is 767. If I do a mount and look at the settings on both host and node then both states that the device has been mounted and heartbeat=local. Also if looking at the mounted.ocfs2 -f it is empty but if I do a mounted.ocfs2 -f /dev/sdc then it shows just the node details and not also the host details as mounted even though it is mounted on the host and accessible (I can cd into the dir on the host and see the contents created on the node). The moment I umount on the node then the error messages stop on the host. It remains mounted on the host as I can cd into it even though the mounted.ocfs2 -f /dev/sdb shows nothing mounted. Any advice? I have been googling the whole day for info on using ocfs2 and iscsi together and the correct procedure to follow but can't find anything of value. In the ocfs2 user guide it states you can export via NFS but doesn't mention iscsi in any way. Also what is unclear to me is how are you suppose to mount a remote file system if you are not making use of something like iscsi, or is it always automatically assumed that the different nodes are all directly attached to the storage? In the guide they just always refer to local block devices in the procedure descriptions but they don't show you how those devices got there? Thanks for the assistance. Werner
