THAT is REALLY bad! > Is this something that we can expect to see changed before 8.0-RELEASE? I'm fairly certain that we've discussed this already. Solaris uses FMA - I don't think that I'll get to a "real fix" any time soon. The time that I do have will go to addressing stability problems (memory over-allocation, NFS interaction, control directory mounts) all of which cause panics. Maintaining them persistently in the label doesn't make sense - when do you drop them? Would a simple log message about the number of checksum errors suffice?
