Actually there can be an impact on disk space. If you have regular files in /proc/pid/fd with link count 0, then this process has a file open, which is not visible in the file system, but consumes disk space. The disk space used will be freed once the process ends or closes the file.
Example:
This file (named dummyfile before it was deleted) still uses 12MB on disk until the sleep command running in the background ends or is killed.
if I have 1000 files, named file1, file2, ... ,file1000. for each one, I want to append a line, for example "this is the end of file#".
then, I want to link them all together.
how can I do that by using a simple script? (1 Reply)

But my below script is not working. It is reading the first file properly but not the subsequent files. Please throw a... (2 Replies)
Hi All,
Please explain me the concept of link counts when you try to view the contents of any file or directory using ls command.

Hi,
I am trying to calculate the CPU Usage by getting the difference between the idle time reported by /proc/stat at 2 different intervals. Now the 4th entry in the first line of /proc/stat will give me the 'idle time'. But I also came across /proc/uptime that gives me 2 entries : 1st one as the... (0 Replies)

Currently my data is organised in a volume which has a cache directory (where all the files are first created or transferred). After that there are suitable directories on the volume which in their subdirs, contain files hardlinked to files in the cache. This is done so that the same inode... (1 Reply)
I run a find command to search from root directory.

Hi Experts,
I had encountered an issue where the zero link process was holding too much amount of data on a Solaris server. I was able to terminate the process after which the space of the file system was released.

prealloc
prealloc(1) General Commands Manual prealloc(1)NAME
prealloc - preallocate disk storage
SYNOPSIS
name size
DESCRIPTION
preallocates at least size bytes of disk space for an ordinary file name, creating the file if name does not already exist. The space is
allocated in an implementation-dependent fashion for fast sequential reads and writes of the file.
fails and no disk space is allocated if name already exists and is not an ordinary file of zero length, if insufficient space is left on
disk, or if size exceeds the maximum file size or the file size limit of the process (see ulimit(2)). The file is zero-filled.
DIAGNOSTICS
returns one of the following values upon completion:
0 Successful completion.
1 name already exists and is not an ordinary file of zero length.
2 There is insufficient room on the disk.
3 size exceeds file size limits.
EXAMPLES
The following example preallocates 50000 bytes for the file
WARNINGS
Allocation of file space is highly dependent on current disk usage. A successful return does not indicate how fragmented the file actually
might be if the disk is approaching its capacity.
