Dear colleagues,
is anyone interested in analyzing vinum crashdumps under RELENG_4? The problem
is that crash situations are not easily reproducible (they are related to
changing in-memory and on-disk vinum configs), but almost every refers
to
#6 0xc01ff69b in __divdi3 (a=0x1000, b=0x0) at /FreeBSD/src.411/sys/libkern/divdi3.c:61
#7 0xc02abc8e in driveio (drive=0xc38e41f8, buf=0xc3c96c00 "IN VINO", length=0x200, offset=0x1000, flag=0x0)
at /FreeBSD/src.411/sys/modules/vinum/../../dev/vinum/vinumio.c:330
which is
330 bp->b_blkno = offset / drive->partinfo.disklab->d_secsize; /* block number */
(in my last case, drive->partinfo.disklab is filled with zeros except d_magic
field)
Thanks in advacne.
Sincerely,
D.Marck [DM5020, MCK-RIPE, DM3-RIPN]
