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.
