|
|
I use Gentoo (hardened) paravirtualized on Xen.
Since i started using the Linux 3.5+ series of kernels i noticed a Kernel Warning on DMESG when mounting OCFS2 in the DOMU.
Code: |
ocfs2: Mounting device (202,32) on (node 4, slot 4) with ordered data mode.

I have tested the 3.5 and 3.6 kernel sources and i get the same Warning.
Even though everything is running, I'm wondering if anyone has an idea what this is (and if there is something that can be done to get rid of it ... No ... taking OCFS2 out is not an option ) |
