[Ocfs2-users] Huge Problem ocfs2

[Marian Serban]

Hi Sunil,

Thank you for answering. Unfortunately, it doesn't seem like it's a 
hardware problem. There's no way a cable can be loose because it's iSCSI 
over 1G Ethernet (copper wires) environment. Also I performed "dd 
if=/dev/.... of=/dev/null" and first 16GB or so are fine. "Dmesg" shows 
no errors.


Also tried with debugfs.ocfs2:
