[Ocfs2-users] OCFS2 and Xen - aio error -14

[Sunil Mushran]

Which kernel?

The error message itself needs to be silenced. The OR should
be changed to an AND.
2184                         if (ret != -EFAULT || ret != -ENOSPC)
2185                                 mlog_errno(ret);

But that just means we are treating this as a user error.

However, as the same works on ext3, something is amiss.

Which gets me to... which kernel? Are you using the 1.4.1 binary rpms
or have ported it to a different kernel? etc.
