Cannot stat Input/Output error
 

I am trying to tar a directory structure and there are 2 files (or something) in the directory that make tar stop and puke. When you do an ls -l the line reads like this:

?--------- ? ? ? ? ? iwssd.shmid
?--------- ? ? ? ? ? iwssd.pshmid

If you try to ls -l the file (or tar it) I get "Cannot stat Input/Output error". As root I cannot remove or stat the files and the application that I believe created is not running nor can it be started.

What options do I have for removing these files?

thanks

"fsck" or "debugfs / clri"

Could you be a bit more specific please. What is my desired goal with these commands ... deletion of the files I assume? What exactly are these files ... it looks like some shared memory file but I thought that was in /dev/shm ?

I'll try.
Yes, I understood that was what you were asking for.
Possibly.
You should know better than the rest of us from where these files are coming. Is this an application specific directory ?
You can have pseudo files anywhere, at least on most file-systems, having them in /dev is just a convention.

Good.
The directory is /etc/iscan. Its Trends proxy / antivirus suite. The suite contains 6 processes. One of these processes is iwssd which coincides with the names of the files.
Thats fine too. I know when we did some shared memory with JNI on Slackware it seemed to be required that we load a tmp fs under /dev/shm.

But besides all that what am I supposed to do with the commands given? They have numerous options.


thanks

Since I m just now getting in front of a linux box to look at these commands I see tha clri is a command/option for debugfs. I assumed it to be another command/tool to try and this is why I was pressing on the options. I had not used debugfs before

I did get it to clear the files. I was actually presently surprised that it handled an LVM filesystem fine.

Thanks again. debugfs is a cool tool.
