[-- Attachment #1 --] I've got a 6.1 server that's panicing and I'd like to debug it. The problem is that I can't get a kernel dump on to my gmirror device. It looks like since 6.1 this has been supported (it says so in the release notes). In my rc.conf I have: dumpdev="/dev/mirror/gm0s1b"$a Which is my swap partition. On booting it says: kernel dumps on /dev/mirror/gm0s1b But when it panics it says: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x14 fault code = supervisor write, page not present instruction pointer = 0x20:0xc057ff9f stack pointer = 0x28:0xe2df3c44 frame pointer = 0x28:0xe2df3c4c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 13 (swi4: clock sio) trap number = 12 panic: page fault Uptime: 1d4h15m55s GEOM_MIRROR: Device gm0: provider mirror/gm0 destroyed. GEOM_MIRROR: Device gm0 destroyed. Cannot dump. No dump device defined. Automatic reboot in 15 seconds - press a key on the console to abort Rebooting... I'm guessing it's because the GEOM_MIRROR device has been destroyed just before it wants to dump? Any suggestions on a way forward to getting a dump out?
