Dear Gurus,
Could it be possible to have the output of df -k sorted? The df -k output messed up after recent power trip.
Also, is there any folders that I should look into to reduce the root size (other than /var/adm and /var/crash) after server crash?
Many thanks in advance.

Hello all,
I'm sharing 1 volume from a Sun Storage array (6130), out to 2 servers. Created a slice on one server and mounted a filesystem. On the other server the disk already sees the created slice from the other server (shared throught the storage array, so mounted this filesystem as well.

REBOOT(2) Linux Programmer's Manual REBOOT(2)
NAME
reboot - reboot or enable/disable Ctrl-Alt-Del
SYNOPSIS
/* For libc4 and libc5 the library call and the system call
are identical, and since kernel version 2.1.30 there are
symbolic names LINUX_REBOOT_* for the constants and a
fourth argument to the call: */
#include <unistd.h>
#include <linux/reboot.h>
int reboot(int magic, int magic2, int cmd, void *arg);
/* Under glibc some of the constants involved have gotten
symbolic names RB_*, and the library call is a 1-argument
wrapper around the 3-argument system call: */
#include <unistd.h>
#include <sys/reboot.h>
int reboot(int cmd);
DESCRIPTION
The reboot() call reboots the system, or enables/disables the reboot keystroke (abbreviated CAD, since the default is Ctrl-Alt-Delete; it
can be changed using loadkeys(1)).
This system call will fail (with EINVAL) unless magic equals LINUX_REBOOT_MAGIC1 (that is, 0xfee1dead) and magic2 equals
LINUX_REBOOT_MAGIC2 (that is, 672274793). However, since 2.1.17 also LINUX_REBOOT_MAGIC2A (that is, 85072278) and since 2.1.97 also
LINUX_REBOOT_MAGIC2B (that is, 369367448) and since 2.5.71 also LINUX_REBOOT_MAGIC2C (that is, 537993216) are permitted as value for
magic2. (The hexadecimal values of these constants are meaningful.) The cmd argument can have the following values:
LINUX_REBOOT_CMD_CAD_OFF
(RB_DISABLE_CAD, 0). CAD is disabled. This means that the CAD keystroke will cause a SIGINT signal to be sent to init (process 1),
whereupon this process may decide upon a proper action (maybe: kill all processes, sync, reboot).
LINUX_REBOOT_CMD_CAD_ON
(RB_ENABLE_CAD, 0x89abcdef). CAD is enabled. This means that the CAD keystroke will immediately cause the action associated with
LINUX_REBOOT_CMD_RESTART.
LINUX_REBOOT_CMD_HALT
(RB_HALT_SYSTEM, 0xcdef0123; since 1.1.76). The message "System halted." is printed, and the system is halted. Control is given to
the ROM monitor, if there is one. If not preceded by a sync(2), data will be lost.
LINUX_REBOOT_CMD_KEXEC (since Linux 2.6.13)
Execute a kernel that has been loaded earlier with kexec_load(2). This option is only available if the kernel was configured with
CONFIG_KEXEC.
LINUX_REBOOT_CMD_POWER_OFF
(0x4321fedc; since 2.1.30). The message "Power down." is printed, the system is stopped, and all power is removed from the system,
if possible. If not preceded by a sync(2), data will be lost.
LINUX_REBOOT_CMD_RESTART
(RB_AUTOBOOT, 0x1234567). The message "Restarting system." is printed, and a default restart is performed immediately. If not pre-
ceded by a sync(2), data will be lost.
LINUX_REBOOT_CMD_RESTART2
(0xa1b2c3d4; since 2.1.30). The message "Restarting system with command '%s'" is printed, and a restart (using the command string
given in arg) is performed immediately. If not preceded by a sync(2), data will be lost.
Only the superuser may call reboot().
The precise effect of the above actions depends on the architecture. For the i386 architecture, the additional argument does not do any-
thing at present (2.1.122), but the type of reboot can be determined by kernel command-line arguments ("reboot=...") to be either warm or
cold, and either hard or through the BIOS.
RETURN VALUE
For the values of cmd that stop or restart the system, a successful call to reboot() does not return. For the other cmd values, zero is
returned on success. In all cases, -1 is returned on failure, and errno is set appropriately.
ERRORS
EFAULT Problem with getting user-space data under LINUX_REBOOT_CMD_RESTART2.
EINVAL Bad magic numbers or cmd.
EPERM The calling process has insufficient privilege to call reboot(); the CAP_SYS_BOOT capability is required.
CONFORMING TO
reboot() is Linux-specific, and should not be used in programs intended to be portable.
