Couldn't attach the serial console yet ;-(. But I had people attach a KVMoverIP switch and enabled the various KDB options in the kernel. Now we can see a bit more (see below) -- no crashdump is being generated though. Some comments on what the crontab script does at 5:01 (I switched it from 5:15 to 5:01 for some reason): 1. Unmount all snapshots 2. Remove all /dev/md devices 3. Deleting the oldest snapshot 4. Generating a new snapshost 5. mdconfig and mount mount of all snapshots I assume the first LOR (sys_unmount) is related to the unmount and the second one (sys_unlink) to the rm. I have added some sleep(1) and sync(1) commands between the different steps but this didn't help. Now the log of three days, we can see another LOR after booting: --- cronjob start, day 1 --- Jun 11 05:01:00 typhon kernel: lock order reversal: Jun 11 05:01:00 typhon kernel: 1st 0xc53644c8 ufs (ufs) @ /src/src-9/sys/kern/vfs_mount.c:1240 Jun 11 05:01:00 typhon kernel: 2nd 0xc5361290 devfs (devfs) @ /src/src-9/sys/ufs/ffs/ffs_vfsops.c:1414 Jun 11 05:01:00 typhon kernel: KDB: stack backtrace: Jun 11 05:01:00 typhon kernel: db_trace_self_wrapper(c0815bdd,662f7366,765f7366,706f7366,3a632e73,...) at db_trace_self_wrapper+0x26/frame 0xec3c98d4 Jun 11 05:01:00 typhon kernel: kdb_backtrace(c063659b,c08198b4,c09e8bb0,586,ec3c99a0,...) at kdb_backtrace+0x2a/frame 0xec3c9930 Jun 11 05:01:00 typhon kernel: _witness_debugger(c08198b4,c5361290,c080d6e7,c4c29338,c0835390,...) at _witness_debugger+0x25/frame 0xec3c9948 Jun 11 05:01:00 typhon kernel: witness_checkorder(c5361290,9,c0835390,586,c53612b0,...) at witness_checkorder+0x86f/frame 0xec3c99a0 Jun 11 05:01:00 typhon kernel: __lockmgr_args(c5361290,80400,c53612b0,0,0,...) at __lockmgr_args+0x829/frame 0xec3c9a58 Jun 11 05:01:00 typhon kernel: vop_stdlock(ec3c9abc,246,c08bcd9c,80400,c5361238,...) at vop_stdlock+0x62/frame 0xec3c9a8c Jun 11 05:01:00 typhon kernel: VOP_LOCK1_APV(c08611e0,ec3c9abc,c09e8bb4,c0890120,c5361238,...) at VOP_LOCK1_APV+0xb5/frame 0xec3c9aa8 Jun 11 05:01:00 typhon kernel: _vn_lock(c5361238,80400,c0835390,586,ec3c9b14,...) at _vn_lock+0x5e/frame 0xec3c9adc Jun 11 05:01:00 typhon kernel: ffs_flushfiles(c5365d34,0,c67ec600,0,c5365d34,...) at ffs_flushfiles+0x133/frame 0xec3c9b1c Jun 11 05:01:00 typhon kernel: ffs_unmount(c5365d34,8000000,c0821043,513,c4c00c08,...) at ffs_unmount+0x180/frame 0xec3c9b5c Jun 11 05:01:00 typhon kernel: dounmount(c5365d34,8000000,c67ec600,494,c67e8378,...) at dounmount+0x423/frame 0xec3c9bac Jun 11 05:01:00 typhon kernel: sys_unmount(c67ec600,ec3c9ccc,c0846650,c081a478,206,...) at sys_unmount+0x3d1/frame 0xec3c9c48 Jun 11 05:01:00 typhon kernel: syscall(ec3c9d08) at syscall+0x24d/frame 0xec3c9cfc Jun 11 05:01:00 typhon kernel: Xint0x80_syscall() at Xint0x80_syscall+0x21/frame 0xec3c9cfc Jun 11 05:01:00 typhon kernel: --- syscall (22, FreeBSD ELF32, sys_unmount), eip = 0x180bf3e7, esp = 0xbfbfd61c, ebp = 0xbfbfd6e8 --- Jun 11 05:01:10 typhon kernel: lock order reversal: Jun 11 05:01:10 typhon kernel: 1st 0xc503545c snaplk (snaplk) @ /src/src-9/sys/ufs/ufs/ufs_vnops.c:976 Jun 11 05:01:10 typhon kernel: 2nd 0xc509eda8 ufs (ufs) @ /src/src-9/sys/ufs/ffs/ffs_snapshot.c:1626 Jun 11 05:01:10 typhon kernel: KDB: stack backtrace: Jun 11 05:01:10 typhon kernel: db_trace_self_wrapper(c0815bdd,735f7366,7370616e,2e746f68,36313a63,...) at db_trace_self_wrapper+0x26/frame 0xec3bd614 Jun 11 05:01:10 typhon kernel: kdb_backtrace(c063659b,c08198b4,c09e96f8,65a,ec3bd6e0,...) at kdb_backtrace+0x2a/frame 0xec3bd670 Jun 11 05:01:10 typhon kernel: _witness_debugger(c08198b4,c509eda8,c0808f48,c4c29470,c0831f9d,...) at _witness_debugger+0x25/frame 0xec3bd688 Jun 11 05:01:10 typhon kernel: witness_checkorder(c509eda8,9,c0831f9d,65a,0,...) at witness_checkorder+0x86f/frame 0xec3bd6e0 Jun 11 05:01:10 typhon kernel: __lockmgr_args(c509eda8,80000,0,0,0,...) at __lockmgr_args+0x829/frame 0xec3bd798 Jun 11 05:01:10 typhon kernel: ffs_snapremove(c509ed50,c4c23f88,c4c26140,4,c09e96f8,...) at ffs_snapremove+0x11f/frame 0xec3bd818 Jun 11 05:01:10 typhon kernel: ffs_truncate(c509ed50,0,0,c00,0,...) at ffs_truncate+0x637/frame 0xec3bda44 Jun 11 05:01:10 typhon kernel: ufs_inactive(ec3bdab8,c509ed50,c509ed50,c535d1bc,ec3bdad0,...) at ufs_inactive+0x1f8/frame 0xec3bda80 Jun 11 05:01:10 typhon kernel: VOP_INACTIVE_APV(c0882560,ec3bdab8,c08219ca,a00,c068657a,...) at VOP_INACTIVE_APV+0xa5/frame 0xec3bda98 Jun 11 05:01:10 typhon kernel: vinactive(c509ed50,c67ee300,c08219ca,8fe,0,...) at vinactive+0x112/frame 0xec3bdad0 Jun 11 05:01:10 typhon kernel: vputx(ec3bdc18,c069fcf4,c509ed50,ffffffdf,2,...) at vputx+0x2fc/frame 0xec3bdb0c Jun 11 05:01:10 typhon kernel: vput(c509ed50,ffffffdf,2,0,5,...) at vput+0x10/frame 0xec3bdb14 Jun 11 05:01:10 typhon kernel: kern_unlinkat(c67ee300,ffffff9c,bfbfdf32,0,0,...) at kern_unlinkat+0x274/frame 0xec3bdc18 Jun 11 05:01:10 typhon kernel: kern_unlink(c67ee300,bfbfdf32,0,ec3bdcfc,c07b310d,...) at kern_unlink+0x2f/frame 0xec3bdc34 Jun 11 05:01:10 typhon kernel: sys_unlink(c67ee300,ec3bdccc,c0846650,c081a4d8,246,...) at sys_unlink+0x22/frame 0xec3bdc48 Jun 11 05:01:10 typhon kernel: syscall(ec3bdd08) at syscall+0x24d/frame 0xec3bdcfc Jun 11 05:01:10 typhon kernel: Xint0x80_syscall() at Xint0x80_syscall+0x21/frame 0xec3bdcfc Jun 11 05:01:10 typhon kernel: --- syscall (10, FreeBSD ELF32, sys_unlink), eip = 0x1814ee83, esp = 0xbfbfdd3c, ebp = 0xbfbfddb8 --- --- reboot on day 1 --- Jun 11 05:35:46 typhon kernel: Copyright (c) 1992-2013 The FreeBSD Project.
