Greetings,
I'm developing on a SXCE build 103 machine. Up to now, kernel dumps have
worked very reliably (have collected more than 100 already...), but
suddenly, kernel panics no longer give me a vmcore on reboot.
While I can see on the console that the kernel is dumped to the indicatd
device, I don't have a vmcore/unix pair of files after reboot as I used
to have. savecore doesn't log any message, either. Here's my setup:
[EMAIL PROTECTED] # dumpadm
Dump content: kernel and current process pages
Dump device: /dev/dsk/c1t0d0s4 (dedicated)
Savecore directory: /export/home/crash
Savecore enabled: yes
/dev/dsk/c1t0d0s4 is 15G; I successfully used the swap slice before, but
tried this one to see if it fixes the problem.
Dumping a live works fine this way:
[EMAIL PROTECTED] # savecore -Lv
dumping to /dev/dsk/c1t0d0s4, offset 65536, content: kernel + curproc
100% done: 127094 pages dumped, compression ratio 4.35, dump succeeded
System dump time: Thu Dec 4 18:44:55 2008
Constructing namelist /export/home/crash/unix.107
Constructing corefile /export/home/crash/vmcore.107
100% done: 127094 of 127094 pages saved
This dump is valid:
[EMAIL PROTECTED] # cd /export/home/crash/
[EMAIL PROTECTED] # mdb 107
mdb: failed to read panicbuf and panic_reg -- current register set will
be unavailable
Loading modules: [ unix genunix specfs dtrace cpu.generic uppc pcplusmp

> ::status
debugging crash dump vmcore.107 (64-bit) from d0
operating system: 5.11 volo-gate-103 (i86pc)
panic message:
dump content: kernel pages and pages from PID 100836
But as I said, a real kernel panic says it dumps to /dev/dsk/c1t0d0s4 as
well, but savecore doesn't do anything on reboot.
Any idea what's wrong? I tried different kinds of panics already...
thanks, Joachim
