Information in this document applies to any platform.
Some customers who require continuous replication to ZFS shares encounter performance issues when trying to conduct scrubs. Since replication has a higher priority then scrubs, the scrubs never complete if replication is busy.

A work around was created and is added via workflow to install the shim library on a running controller called "Improve Scrub Performance" (synchronize_receive.akwf).

Multiple versions of this workflow are in circulation with different versions of the library and environment settings.

A new workflow was created to verify the correct "shim" library is properly installed and configured.




Goal

To verify a customer using the "Improve Scrub Performance" workflow has the correct version installed and it is properly configured.

 

The "Improve Scrub Performance" workflow is only recommended once Oracle Support has identified a system with continuous replication being effected by Bug 29173933

ZFS admin ops shouldn't prevent scrub from making reasonable progress

If you suspect your system is effected by this bug, please open a service request for assistance.
