I now have a dump, but it does not seem to be correct...... ======== opteron# savecore -v checking for kernel dump on device /dev/ad0s2b mediasize = 5368709120 sectorsize = 512 savecore: parity error on last dump header on /dev/ad0s2b savecore: unsaved dumps found but not saved ======== Is this because I 'call doadump' which is not appropriate??? Or are the headers really mangled... And then why?? --WjW
