Okay, let's see...
/dev/ad0 and /dev/ad2 are identical drives (Hitachi TravelStar 2.5"
7200RPM 60GB)
/dev/ad0s1a is 128MB for / - 54% capacity
/dev/ad0s1b is 256MB for swap
/dev/ad0s1d is 56.3GB for /usr - 11% capacity
/dev/ad2s1a is 128MB for /mnt/root - 54% capacity
/dev/ad0s1b is 256MB for swap
/dev/ad0s1d is 56.3GB for /mnt/usr - 11% capacity max
Basically, /mnt/root is a clone of / and /mnt/usr is a clone of
/usr which is done as follows:
cd /mnt/root
/bin/chflags -R noschg .
/bin/rm -rf .*
/bin/rm -rf *
/sbin/dump -L -f- /|restore -rf-
cd /mnt/usr
/bin/chflags -R noschg .
/bin/rm -rf .*
/bin/rm -rf *
/sbin/dump -L -f- /usr|restore -rf-
/mnt/usr is the one with the problem I mentioned which is due to
an upgrade of -CURRENT to February 28, 2003 and even March 5, 2003 from
the September 26, 2003 which was working fine but now whenever this script
executes at 4AM, it causes a kernel panic with the following:
panic: kmem_malloc (4096): kmem_map too small: 377487360 total allocated
at line 341 in file /usr/src/sys/vm/vm_kern.c
cpuid=0;
Debugger("panic")
Stopped at Debugger+0x46: xchgl %ebx, in_Debugger.0
db>
The script runs fine if I do it manually after a few minutes after
a reboot.
I've tried adding the following to the kernel config, building and
installing the kernel
options VM_KMEM_SIZE_MAX=(768*1048576)
options VM_KMEM_SIZE_SCALE=2
as well as adding vm.kmem_size=429391872 to /boot/loader.conf to the
without the above options and they both panic right after this part:
CPU: Mobile Intel(R) Pentium(R) 4 - M CPU 2.60GHz (2592.36-MHz 686-class
CPU) Origin = "GenuineIntel" Id = 0xf29 Stepping = 9
Features=0xbfebf9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,P
AT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
real memory = 2147360768 (2047 MB)
avail memory = 2095669248 (1998 MB)
with something having to do with vm_kern.c.
