[Ocfs2-users] ocfs2 questions

[Pearson, Mark]

I posted this message last week and haven't gotten any responses (could have slipped into the spam filter).  I'll take another chance, any comments would be appreciated.

> We are in the process of upgrading to OCFS2.  We have recently restored our Production Database to a Development platform configured with OCFS2 with RMAN.  No problems.  As for the Production migration, we understand that you cannot mount an OCFS volume (our current configuration) with OCFS2.  We are interested in mounting an EXT3 file system, performing a cold RMAN backup, copying the datafiles to the EXT3 volumes, wipe the OCFS volumes and redo as OCFS2, then copy the datafiles from EXT3 to OCFS2. Bottom line is we don't have the disk space to configure the OCFS2 with the RAID protection we desire.  Is this a valid approach to the migration?
