Operating Systems AIX How to Link FS to 2 directories? Post 302523895 by methyl on Friday 20th of May 2011 07:16:07 AM

Sorry, but your question imples an impossible solution.

Are /lhome , /u and /home all separately mounted local filesystems which appear as separate lines in "df" ?

What are you trying to achive?

I have in the past linked say /home/myuser to another filesystem where a user wanted more disc space and had programs which expected /home/myuser. Is this the sort of thing?

Sorry, but your question imples an impossible solution.

What are you trying to achive?

I have before linked say /home/myuser to another filesystem where a user wanted more disc space and had programs which expected /home/myuser. Is this the sort of thing?


After re-reading your posts. Maybe you have a filesystem called /lhome but do not have filesystems called /u and /home?
In this circumstance the "ln -s" commands in post #2 should have worked. If /home existed already (or perhaps /lhome is a file not a directory) then that is why the command failed.
Can we check with:
Code:
ls -lad /lhome
ls -lad /home
ls -lad /u
df -k       # Or whatever the command is on your system to give free space in all filesystems

link(1M)						  System Administration Commands						  link(1M)

NAME

       link, unlink - link and unlink files and directories

SYNOPSIS

       /usr/sbin/link  existing-file new-file

       /usr/xpg4/bin/link  existing-file new-file

       /usr/sbin/unlink  file

DESCRIPTION

       The link and unlink commands link and unlink files and directories. Only super-users can use these commands on directories.

       Use  link  to  create  a new file that points to an existing file. The  existing-file and  new-file operands  specify the existing file and
       newly-created files.  See OPERANDS.

       link and  unlink directly invoke the link(2) and unlink(2) system calls, performing exactly what they are told to  do  and  abandoning  all
       error checking. This differs from the  ln(1) command. See  ln(1).

       While linked files and directories can be removed using unlink, it is safer to use rm(1) and rmdir(1) instead. See  rm(1) and  rmdir(1).

   /usr/xpg4/bin/link
       If  the	existing  file being hard linked is itself a symbolic link, then the newly created file (new-file) will be a hard link to the file
       referenced by the symbolic link, not to the symbolic link object itself (existing-file).

OPERANDS

       The following operands are supported:

       existing-file   Specifies the name of the existing file to be linked.

       file	       Specifies the name of the file to be unlinked.

       new-file        Specifies the name of newly created (linked) file.

ENVIRONMENT VARIABLES

       See  environ(5) for descriptions of the following environment variables that affect the execution of  link: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, and NLSPATH.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
