Hello all, I hope this is the right mailinglist. One of our machines running gmirror has become unstable and seems to panic at times. I would like to enable crash dumps which requires dumping to a swap partition. My problem is: all the partitions are gmirror-ed, and gmirror partitions can't be used with dumpon because GEOM is already down at the time of dumping. Someone on a mailinglist had suggested to dump to one of the gmirror components directly (/dev/ad4s1b in my case). This would bring the disks out of sync, although it wouldn't be critical if dumping works exactly as planned. Nevertheless, it would be devastating if I'd ruin the mirror set. Is this practice recommended? I also don't seem to have an entry for ad4s1b in /dev, is there a way to get around this? How do people using gmirror exclusively handle the problem of saving crash dumps? Any help would be appreciated! Kind regards, Walter Hop Transip BV -- Dieses Schreiben wurde mit Hilfe einer Datenverarbeitungsanlage erstellt und bedarf daher keiner Unterschrift.
