That's compressed vmcores :) For compressed dumps, see http://dan.allantgroup.com/FreeBSD/ . It's more than a proof-of-concept (I use it on multiple systems), but is not committable as is (see comments at the top of the diff). The ability to do kmem-only sparse dumps would reduce the necessity of true compressed dumps. -- Dan Nelson dnelson_at_allantgroup.comReceived on Mon May 03 2004 - 09:22:13 UTC
