New user added but having error in AIX 7.1

aixunixuser-management

I newly add a user name perfmgr in AIX 7.1 using smitty, however when I try to change the password it output and error as below:

# passwd perfmgr
Changing password for "perfmgr"
3004-616 User "perfmgr" does not exist.
3004-709 Error changing password for "perfmgr".
#

Im using root to run above command.

This is quite weird since I can see this user perfmgr are available under /etc/passwd:

# grep perfmgr /etc/passwd
perfmgr:*:208:1::/space/perfmgr:/usr/bin/ksh
#

Then I try to remove this user using smitty, but same error occurred again,

User "perfmgr" does not exist.

Need advise for this issue since cannot found the correct way to remove or fix this user.

I found the issue, the issue is there are no registry line for user perfmgr under /etc/security/user file.

perfmgr:
        admin = false
        registry = files

However, before that I fix the other thing where my perfmgr are not sync with other file using below command,

pwdck -y perfmgr

Then, after I run this command I proceed to manually create 'registry=files' line under /etc/security/user file as above.

Hope this helps other user which encountered this issue.

AIX: Howto setup a new /home directory on a new harddrive

Meanwhile I found a solution for the topic mentioned. But I would like to let others know how I did that.

I found this great description from a guy whose name is "Ryan".

see: Ryan's AIX description

The only thing I had to change was: use jfs instead of jfs2 (for whatever reason).

Here is a summary of the commands I used to get this working:

1. mkvg -y homevg hdisk1                    # create a new volume group on the new/free  harddisk
2. mklv -t jfslog -y loghomevg homevg 1     # prepare log for the new filesystem
3. mklv -t jfs    -y    homelv homevg 64G   # prepare a 64G partition for the new /home
4. mkfs -o log=/dev/loghomevg  -V jfs /dev/homelv # create new jfs filesystem.
5. mkdir /home2                             # create a mountpoint for the new filesystem
6. chown bin:bin /home2                     # set ownership according to /home
7. mount -o log=/dev/loghomevg  /dev/homelv /home2 # mount the new filesystem

Note: in (4) you have to answer with "Yes". Afterwards it will take a while to complete.

After all that I copied the original content of the /home directory to /home2. I did so by using gnu tar, but other approaches should also work:

cd /home
gtar -cvpf - * | gtar -C /home2 -xpf -

you are done now!

finally you could unmount /home and use /home2 as the new /home directory, e.g. by modifying /etc/filesystems appropriately. Alternatively you could assign a new home directory to the users defined in /etc/passwd, e.g. use /home2/buildsys instead of /home/buildsys

Unable to remove file using ‘rm’

It sounds like this filename may contain a non-printable character. That would explain "touch" making a different file.

Try something like

       ls -b

in the directory to see if that's the case?

Then you should be able to do something like:

       rm -i S*2

and it should prompt you for the file even with the hidden character.

Alternately, you may be able to use find to do this...

       find . -name S\*2 -exec /bin/rm -i {} \;

should prompt you for the files... I don't know if AIX 'find' syntax is unusual so this might not work, but the 'rm -i' part should let you abort the command if it's wrong.
