Name: ada2 Mediasize: 2000398934016 (1.8T) Sectorsize: 512 Mode: r2w2e5 [mikej@charon ~]$ ls /dev/ada2 ada2 ada2s1 ada2s1a ada2s1b [mikej@charon ~]$ ls /dev/ada2 I simply must just not understand something that is fundamental here. If I get this right swap is a slice ada2s1b, not a partition which should be fine for core dumps right? On reboot dumps to swap are not being wrote to /data/dump! If UFS is dirty and auto-fsck runs - is this an issue? I obviously don't get something. Please someone enlighten me ;-) Regards, --mikej Michael Jung
