On r209586 I have 2 fibre disks (da1, da2). I added another and did 'camcontrol rescan all'. I got the disk detected as da3. I did "gpart -c gpt da3" successfully. I added a UFS partition successfully: mech-as28# gpart add -t freebsd-ufs da3 da3p1 added However "gpart show" would segfault. In addition devices /dev/da1 and /dev/da2 vanished. I decided to reboot and got this: - - - - - - - - - - - - Live Console - - - - - - - - - - - - fatal kernel trap (cpu 0): trap vector = 0x14 (Page Not Present) cr.iip = 0xe00000000439f2c0 cr.ipsr = 0x1210080a6010 (mfl,ic,i,dt,dfh,rt,cpl=0,it,ri=1,bn) cr.isr = 0xa0400000000 (code=0,vector=0,r,ei=1,ed) cr.ifa = 0x18 curthread = 0xe000000010f9c3c0 pid = 2, comm = g_event [ thread pid 2 tid 100008 ] Stopped at g_access+0x41: [M1] ld8 r36=[r14] db> bt Tracing pid 2 tid 100008 td 0xe000000010f9c3c0 g_access(0x0, 0xffffffffffffffff, 0xffffffffffffffff, 0x0) at g_access+0x41 swapgeom_close_ev(0x0, 0xe0000000043977f0, 0x814, 0xd9) at swapgeom_close_ev+0x30 g_run_events(0xe000000011443b00, 0x0, 0xe000000004aae500, 0xe000000004925888, 0xe000000004aaba38) at g_run_events+0x6c0 g_event_procbody(0xe000000004a9c084, 0xe00000000491cd10, 0xe000000004a9b8c8, 0xe000000004401ca0) at g_event_procbody+0xf0 fork_exit(0xe000000004977400, 0x0, 0xa0000000eaf1b550) at fork_exit+0x110 enter_userland() at enter_userland db> I'll complete the reboot and see from there. -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423
