Check error code

[Cheung_2]

Where can i check the error code of Red Hat linux, can someone suggest any web site or document to check the meaning of error code? thx.

The error code for Red Hat Linux.. You wanna be a little bit more specific?

The error code of what application at what point?

If you're talking about "during installation", then that will narrow down the possibilities of things launched by 'anaconda'.

What were you doing when this mysterious error occured, and what was the error?

The question as you've asked it is far too broad. Please be a little more specific.

For example ,
I got the below error from the log :
EDP kernel: VFS: Error -5 occured while creating quota.

What is the error code mean? where can i check it? thx.

hi,
You can find the system error
codes in :

/usr/include/asm/errno.h

error 5 means :

define EIO 5 /* I/O error */

rgds.

The quickest and easiest way is to use the command

perror {errornumber}

eg

# perror 5
Error code 5: Input/output error
#
