[Ocfs2-users] input / out error on some nodes

[Eric Ren]

Hi Prabu,

I guess others like me are not familiar with this case that combine CEPH 
RBD and OCFS2.

We'd really like to help you. But I think ocfs2 developers cannot get 
any info about what happened
to ocfs2 from your descriptions.

So, I'm wondering if you can reproduce and tell us the steps. Once 
developers can reproduce it,
it's likely be resolved;-) BTW, any dmesg log about ocfs2 especially the 
initial error message and stack
back trace will be helpful!

Thanks,
Eric
