I just got word that you only need to update the active file system manager node… I’ll let you know if I hear differently,

Can anyone from IBM confirm whether this only affects manager nodes or if parallel log recovery is expected to happen on any other nodes?

Thx

Has anyone been hit by this data corruption issue and if so how did you determine the file system had corruption?

Thanks!
