RELENG_5: panic: ffs_blkfree: freeing free block
RELENG_5 sources from yesterday. This was after attempting a dump -L (snapshot before dump) on a huge (5TB) gconcat filesystem while scp'ing massive amounts of data to it. The snapshot failed with ETOOLARGE; the system became very sluggish after that then paniced a few minutes later. I'm keeping a copy of the crash dump and debug kernel in case someone wants to know more. #13 0xc05524a0 in ffs_blkfree (fs=0xc990f800, devvp=0xc4aa4840, bno=1, size=16384, inum=1) at ../../../ufs/ffs/ffs_alloc.c:1751 #14 0xc0560913 in indir_trunc (freeblks=0xc83c6700, dbn=5677551840, level=0, lbn=268441612, countp=0xe64ffc3c) at ../../../ufs/ffs/ffs_softdep.c:2628 #15 0xc05608ed in indir_trunc (freeblks=0xc83c6700, dbn=5676799200, level=1, lbn=268437516, countp=0xe64ffc3c) at ../../../ufs/ffs/ffs_softdep.c:2624 #16 0xc05608ed in indir_trunc (freeblks=0xc83c6700, dbn=8097653792, level=2, lbn=4196364, countp=0xe64ffc3c) at ../../../ufs/ffs/ffs_softdep.c:2624 #17 0xc0560474 in handle_workitem_freeblocks (freeblks=0xc83c6700, flags=0) at ../../../ufs/ffs/ffs_softdep.c:2483 #18 0xc055dbf4 in process_worklist_item (matchmnt=0x0, flags=0) at ../../../ufs/ffs/ffs_softdep.c:758 #19 0xc055d984 in softdep_process_worklist (matchmnt=0x0) at ../../../ufs/ffs/ffs_softdep.c:624 #20 0xc04f9fd2 in sched_sync () at ../../../kern/vfs_subr.c:1675 #21 0xc049cb04 in fork_exit (callout=0xc04f9bb8 sched_sync, arg=0x0, frame=0xe64ffd48) at ../../../kern/kern_fork.c:807 #22 0xc05aa3cc in fork_trampoline () at ../../../i386/i386/exception.s:209 -- A: Yes.
