You don't say how vinum if configured. RAID 5 by any chance? It looks exactly like something I ran into a while back with a 29160 based system. In my casual glancing at the various "control blocks" being used it looked like outstanding requests complete after the parent data structure is freed (at least the pointers are NULL). This was all a little while ago and the details are a little sketchy. Only RAID 5 exhibited the problem. I'm running the array as RAID 0 with no problems. -- Andy Newman, Principal Software Engineer, Silverbrook Research On Fri, 20 Oct 2000, Andy Newman wrote:

Yes, it's running RAID-5.
But, glance at kdb session advises that could be a SCSI related problem,
rather than vinum one.

done on Sun Oct 22 10:02:36 2000 When I had this problem and had a (very) brief debug session the panic was occurring on a dereference of the parent pointer in the buffer. Are there assumptions about completion ordering? (I didn't read the vinum code so excuse me if this is a stupid question). Or is it just an artifact odd SCSI interaction? -- Andy Newman, Principal Software Engineer, Silverbrook Research I took another dump today, it crashed in the same place: #63 0xc150fc67 in complete_rqe () at /usr/src/sys/modules/vinum/../../dev/vinum/vinuminterrupt.c:199 #64 0xc0178d6b in biodone (bp=0xc1caf820) at ../../kern/vfs_bio.c:2637 #65 0xc0126bb9 in dadone (periph=0xc14ca700, done_ccb=0xc184c800) at ../../cam/scsi/scsi_da.c:1246 --Roman Shterenzon, UNIX System Administrator and Consultant [ Xpert UNIX Systems Ltd., Herzlia, Israel. Tel: +972-9-9522361 ] Responsible Changed From-To: freebsd-bugs->grog grog is Mr. Vinum. Hi, See also PR kern/21148 I ran into very similar problems. I could track the crash in periodic daily to the /etc/security script and the find statement within, checking for files with setuid bit set. I could crash the machine reproducable, just by calling find /the/vinum/fs/mountpoint It, too, happened as soon as there has been a bit of data on the fs (~ 70 GB).

So, if Greg will need some additional information you will be able to supply it. Any ideas when this thing began? Our server worked flawlessly for one month, then the problems began. I suspect that it had something to do with some fs fill watermark. What scsi (if any) adapters do you have? I had one guy (and me) look at the stack trace and it looks like the stack was smashed. At least the man page's BUGS section should state that RAID-5 is not stable yet. --Roman Shterenzon, UNIX System Administrator and Consultant [ Xpert UNIX Systems Ltd., Herzlia, Israel.
