Ocfs2 users - Aug 2008 - migration methods (ocfs <-> ocfs2)

Hi everyone;

 

we have a production system with 6 nodes of RAC upon ocfs file system. We will
upgrade our production system that we prefer and (also should) to migrate our
data to ocfs2. Both methods of migration, fscat and backup/restore could be
useful for us but one thing that we could not find is

1)       If we are using fscp fort he migration method can we use fscp to pass
data from ocfs to ocfs2. is fscp biwise, it can copy either ocfs to ocfs2 and
also ocfs2 to ocfs?

2)       For backup/restore the doubt is the same. We can restore ocfs backup to
an ocfs2, could we also restore ocfs2 backup to an ocfs volume?

 

 

Thanx a lot

No, the fscat tools can only read certain unmounted file systems.
They cannot write. You can use it to copy data from ocfs
to ocfs2 on a box running the 2.6 kernel (sles9/10, el4/5).

According to the FAQ of OCFS2, OCFS only works on 2.4 kernels and OCFS2 
only works on 2.6 kernels. So you can't mount both of them on the same 
machine simultaneously. But you can access OCFS volume on 2.6 kernels by 
fscat, fsls and fscp. So you can only cope files from OCFS to OCFS2.

Same as above.
