PowerHA 7.2
Abstract
Potential undetected data loss after PowerHA failover, during jfs2 filesystem recovery
Description
When a PowerHA node acquires a jfs2 filesystem that had not been cleanly unmounted, such as after a crash or halt, the filesystem log may not be replayed when fsck is executed on the filesystem.
This may result in undetected data loss as the filesystem is brought to a consistent state without replaying the log.

This table describes which active levels are affected and where to obtain fixes.
Before the APAR fix is available, an interim fix (iFix) is available for each affected level.
The available interim fixes might apply only to the latest Service Packs. If a custom interim fix is required, contact IBM Support. The interim fixes can be downloaded from the same location by using HTTPS or FTPS.
