When mounting the disks again, the sizes was the same and the same as node1 when running 1.4.7. When I’m writing this, I can see that not only the ocfs2 disks are different. I see that also the OS disks on ext3 file system is different. When I check them against the nodes now, it’s all equal and no differences. Has anybody experienced something like this?
