UNIX for Dummies Questions & Answers

Hi All,
One of the dir has a subdir in it. Subdir has no files in it. I verified it using ls -la command.

When I try to remove this subdir, it says that this directory is not empty.



It does not show any files under it, so what could be the issue??

Appreciate help in this.....

Thanks in advance.

I tried to give 777 mod to subdir and dir and tried to delete the direct directory

/dir/subdir

It says I/O error

So I guess there is some sort of disk error, correct??

Did you try rm -f /dir/subdir ?

Just thoughts:
Did you do a df -k to see where on what is the subdirectory?
Did you check no process is accessing that subdir: fuser -cu <subdir or file system>

Please post real directory listings in "ls -lisaR" format, the exact command typed and the exact error message with all punctuation.

Also try "find" to see if it names the missing files:

Code:

find /dir -print

What Operating System and version is this?

Does the bad directory appear in /etc/fstab ? i.e. is it a mountpoint?

Do you have a good and recent backup? If not, don't reboot until you have saved what you can.
Normally this sort of fault can be either cleared silently or made into a firm fault by cold rebooting the computer. This should force a hardware check and if the disc has not failed trigger a "fsck" on the filesystem.

Hi All,
Thanks for your replies. I will try to post the answer to questions posed by various folks.

This is on AIX V5.3. There is a subdir called PowerCenter in main file system /opt/informatica.

/opt/informatica/PowerCenter contains another subdir called ia_jre_extraction_dir_6222.tmp

1) I went to /opt/informatica and issued following command:

Code:

       rm -rf PowerCenter/ia_jre_extraction_dir_6222.tmp

and it did not work.

2) I tried doing fuser -cu PowerCenter/ia_jre_extraction_dir_6222.tmp
and it shows following output

Code:

PowerCenter/ia_jre_extraction_dir_6222.tmp:    598406c(zdadmin)

So not sure if 598406 is a process, I did not see in list when I issue "ps -ef" command.

3) When I issue the command

Code:

    ls -lisaR   PowerCenter/ia_jre_extraction_dir_6222.tmp

I get the response

Code:

PowerCenter/ia_jre_extraction_dir_6222.tmp/jre not found
total 4
281216    0 drwxr-xr-x    3 zdadmin  zdupdt          256 Jan 31 17:00 .
225258    4 drwxrwxr-x    4 zdadmin  zdupdt         4096 Jan 31 23:33 ..

Mount point is /opt/informatica.

Does the bad directory appear in /etc/fstab ?

I did not see /etc/fstab, is it a text file??

Should I ask my UNIX Admin to reboot the server and see if the I/O errors related to filesystem are resolved.

Please use next time code tags for your code and data

I/O error is bad. It means that the system is physically unable to do what you're asking it to because the disk is not responding as expected. And you ignored the question about whether you have a recent backup, so I'm assuming you don't.

Rebooting isn't a good idea in these circumstances. What if the system just doesn't boot again? You'll have lost your last chance to recover your data.

BACK UP IMMEDIATELY. Do not wait. The disk may be DYING.

This deleted file or directory is still open by process ID 598406 under user xdadmin :
PowerCenter/ia_jre_extraction_dir_6222.tmp/jre
It should show in:

Code:

ps -fp598406

I expect that you are going to need to shut down Informatica as tidily as possible, reboot and repair any damage to Informatica data (possibly be restoring deleted files and directories from backup) before restarting Informatica.

The I/O error message is ominous unless it comes from a Java application. Still advisible to take a new backup before rebooting.
