Compute node disk expansion resulted in mount.ocfs2: Bad magic number in superblock while opening device /dev/sda3

Before Christmas 2017 I had the honour to expand the compute node storage for a virtualised exadata. Better said, OVM on exadata. This can be done for several reasons. The most logic one, also the reason why this customer bought the disk expansion, is that you want to create more virtual machines and you have ran out of space on /EXAVMIMAGES. The preparation is actually pretty simple. It is documented completely in the Exadata Database Machine Maintenance Guide. And look,…

Creating the database using dbca, works as expected. But then it was time to create a container database using the create database statement. The best thing to do is follow the official oracle documentation. Find it here: http://docs.oracle.com/database/121/ADMIN/cdb_create.htm#ADMIN13529 all steps are normal until running the catcdb.sql-script. When running it from a oel6.5 with a default (non-patched)…
