Phantom space usage in /
Hi everyone,
Got an interesting one (well, interesting to me)
I have a box with a 5Gb / mount point. Checking for large files I found nothing and in fact when I did a full du I found that there was only 1.6Gb in use! And yet 100% used in /
So there's an unaccounted 3.4Gb somewhere!
The box isn't running oracle but I thought I'd check lsof |grep deleted anyway and found nothing in that mount point.
Did an inode check and only 14% of inodes are in use.
Any idea what i can do to track down phantom files or do you think I might just have to bounce the box and see if something has held some disk space open for some reason? I'd rather not bounce it as it's running a live service.
Thanks

getfsent
GETFSENT(3) Linux Programmer's Manual GETFSENT(3)
NAME
getfsent, getfsspec, getfsfile, setfsent, endfsent - handle fstab entries
SYNOPSIS
#include <fstab.h>
void endfsent(void);
struct fstab *getfsent(void);
struct fstab *getfsfile(const char *mount_point);
struct fstab *getfsspec(const char *special_file);
int setfsent(void);
DESCRIPTION
These functions read from the file /etc/fstab. The struct fstab is defined by:
struct fstab {
char *fs_spec; /* block device name */
char *fs_file; /* mount point */
char *fs_vfstype; /* file-sysem type */
char *fs_mntops; /* mount options */
const char *fs_type; /* rw/rq/ro/sw/xx option */
int fs_freq; /* dump frequency, in days */
int fs_passno; /* pass number on parallel dump */
};
Here the field fs_type contains (on a *BSD system) one of the five strings "rw", "rq", "ro", "sw", "xx" (read-write, read-write with quota,
read-only, swap, ignore).
The function setfsent() opens the file when required and positions it at the first line.
The function getfsent() parses the next line from the file. (After opening it when required.)
The function endfsent() closes the file when required.
The function getfsspec() searches the file from the start and returns the first entry found for which the fs_spec field matches the spe-
cial_file argument.
The function getfsfile() searches the file from the start and returns the first entry found for which the fs_file field matches the
mount_point argument.
RETURN VALUE
Upon success, the functions getfsent(), getfsfile(), and getfsspec() return a pointer to a struct fstab, while setfsent() returns 1. Upon
failure or end-of-file, these functions return NULL and 0, respectively.
CONFORMING TO
These functions are not in POSIX.1-2001. Several operating systems have them, e.g., *BSD, SunOS, Digital Unix, AIX (which also has a getf-
stype()). HP-UX has functions of the same names, that however use a struct checklist instead of a struct fstab, and calls these functions
obsolete, superseded by getmntent(3).
NOTES
These functions are not thread-safe.
Since Linux allows mounting a block special device in several places, and since several devices can have the same mount point, where the
last device with a given mount point is the interesting one, while getfsfile() and getfsspec() only return the first occurrence, these two
functions are not suitable for use under Linux.
