[Ocfs2-users] No space left on device error, older kernels?

[Herbert van den Bergh]

You don't need to buy a support license to use Oracle Linux.  You can 
download and use it for free.  You can configure your system to get the 
Unbreakable Enterprise Kernel from public-yum.oracle.com.

You don't need to "upgrade" to Oracle Linux to install the Unbreakable 
Kernel, as long as the distro you are using is binary compatible with 
Red Hat / Oracle Linux.  If you added third party modules to your 
system, you will have to get new ones for the Unbreakable Kernel.  
Otherwise you should be able to just drop it in place.

Oracle has not dropped support for OCFS2 on EL5.  Yet.  But some 
problems are too difficult to fix in the older version.  The decision 
was made that fixing this particular problem in the old OCFS2 version 
was more risky than living with the problem.

Thanks,
Herbert.
