Hi people.
Yesterday i was trying to setup another backup server with FreeBSD 6.1 and
Bacula.
This is my first time that i work with one Dual Core system and FreeBSD.
This is the system:
FreeBSD 6.1-RELEASE #0: Sun May 7 04:42:56 UTC 2006

Trying to mount root from ufs:/dev/ad4s1a
start_init: trying /sbin/init
SMP: AP CPU #1 Launched! <This doesn't tell me that he just is going to use
1 CPU...?>
The hard disk is one WD 320GB SATA, which just see 305GB but this is another
history!!
The layout i was trying to setup for the disk was:
/ 512MB
SWAP 2000MB
/usr 20480MB
/var 8192 MB
/home 2048MB
/tmp 1024MB
/backups 264GB
With this layout the system didnt in boot multi-user enviroment, just
single-user, and the error was:
start_init: trying /sbin/init
.:Out of File Descriptors
The system just let me go into single-user mode.
I modify /boot/loader.conf
kern.maxfiles="" # Set the sys. wide open files limit
kern.maxproc="" # Set the maximum # of processes
kern.maxssiz="" # Set the max stack size
kern.maxusers="" # Set size of various static tables
I play with this values, the last value that i use was kern.maxusers = 8192
which crash my system with a Kernel Trap 12, I couldnt recover my system,
doesnt even let go to Single-User Mode.
Ok for this i googling around but nothing clear, i setup freebsd about 10
times, i use GENERIC and SMP kernel and the same problem, different
settings, a lot of time invest.
After a will, i decide to setup the disk with the "Automatic" Layout and
GENERIC kernel only and WOW my system boot in Multi-User enviroment,
no more"Out of File Descriptor".
Them i decide to boot with SMP kernel and again, a success!!!
Them i start working with the disk, i use the same layout except for /home:
/ 512MB
SWAP 2000MB
/usr 20480MB
/var 8192 MB
/tmp 1024MB
/backups 267GB
Load both GENERIC && SMP kernels, and everything is working right now, i
just want to know if thereis a problem between the Disk Setup or Layout and
the Kernels...?
Why and how i fix this problem of "Out of file descriptors"...?
Right now, i will customize my kernel, i wouldnt do the BuildWorld stuff,
because this is a remote system, until next week will visit this system and
rebuild everthing.
Thanks all for your time, greetings!!!
