Hi List, I want to use DLMFS of OCFS2 to avoid multiple start of virtual machines on OracleVM. I want to use a wrapper around xm that spawns a deamon that keeps a file open in /dlm/DOMAIN. Now I played around a bit and followed the procedure in the document http://oss.oracle.com/projects/ocfs2/src/branches/ocfs2-1.2/dlmfs.txt...

The versioning information is confusing for end-users. The numbers are stuck at 1.5.0 when the tools have moved to 1.8.3. I suggest removing the versioning system in the kernel altogether and let the kernel version be the guide to debug issues. However, if you think versioning is still required, please state the reason and modify the version string in the ver.* files to reflect the uptodate

Does anyone have any idea what to try next? Here are the steps I have taken and the problem: (I wanted to post my question on the first line before I explained the problem and what I have tried) ---------- Node 0 has the file system mounted just fine and works great. When trying to mount on Node 1: `mount.ocfs2 /dev/mapper/data /cluster/ data` I get this error after about 30 seconds:

Something blocked the NFS access from both nodes, one rebooted and the another we restarted the nfsd and it brought him back. Looking at node #0 - the one that rebooted - logs everything seems normal, but looking at the othere node dmesg's we saw this messages: First the o2net detected that node #0 was dead: (It

We are using the official XEN 3.1 release on a rackable server (Dual-Core AMD Opteron, 8GB RAM). The problem we are seeing is that intermittently vifs fail to work properly in VMs after we create around 15-17 VMs on our server (all running at the same time, created one by
