So, it seemly has something to do with iscsi stuff. Could you take a look at this? -- You are receiving this mail because: You are on the CC list for the bug.

Now I tend to use iscsi disk on 207.237. For my perspective, I prefer reserving 237 server. Two main reasons are: 1. the disk has around 300GB, it's too small; For ocfs2, we need at least 100G shared disk for each cluster according our experience; 2. looks like it's also too slow, resulting in continuous disconnection.
