https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276944 Bug ID: 276944 Summary: no kernel panic after forcible unmount of / Product: Base System Version: 13.2-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jfc@mit.edu Created attachment 248309 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=248309&action=edit crash screenshot My system was hung because the kernel failed to panic after / was forcibly unmounted due to an I/O error. There is code in ffs_fsfail_cleanup_locked to panic in this case. It did not work. The system kept running but processes crashed as they tried to page in from the bad disk. Key lines below. See attached screenshot for more. There are no log messages because /var/log/messages is on the bad disk. I am running a stable/13 kernel ("13.3-STABLE") on an old amd64 system. g_vfs_done():ada0p2[WRITE(offset=1392508928, length=20480)]error=6 UFS: forcibly unmounting /dev/ada0p2 from / swap_pager: I/O error - pagein failed -- You are receiving this mail because: You are the assignee for the bug.home | help
