Use the following information to determine possible solutions
to problems with the Db2 cluster file
system,
which is based on IBM® Spectrum Scale.
What if the IBM Spectrum Scale cluster
failed to be created?
During instance creation, the IBM Spectrum Scale cluster
might fail to be created. This failure will trigger an instance creation
rollback. Review the log file found in the DB2DIR/tmp directory.
The db2cluster command is used to create an instance.
The db2cluster command log file can be found in DB2DIR/tmp/ibm.db2.cluster.*.
After reviewing the contents of that log file, contact IBM Software Support.
What if the IBM Spectrum Scale cluster
fails to extend to the target host?
If the IBM Spectrum Scale cluster
extension to the host fails, you can review the log file, found in
the DB2DIR/tmp directory to determine why the
extension was prevented on that host.
What if the "GPFS_CLUSTER" global registry variable
record on the target hosts was not created?
As with any errors,
review the installation log for specific details. Ensure that the IBM Spectrum Scale cluster
has been properly created. If the log indicates that the GPFS_CLUSTER
global registry variable record was not created on the specified hosts,
contact IBM Software
Support.
What if the IBM Spectrum Scale cluster was not
deleted during a failed installation?
If a failed attempt to install a Db2 product results in a
rollback, the Db2 installer might be unable to remove the newly created IBM Spectrum Scale file system. To
understand why the IBM Spectrum Scale cluster was not
removed, review the log file found in the DB2DIR/tmp
directory .
