Hi,

Try running this command on your system, it should hopefully show you the error that list_expander is finding:

/opt/ignite/lbin/list_expander -l /tmp/list_exander.out -S -C -f

Where should contain:

inc_entire vg00

Hi Richard,

Thanks for the reply..

You have a circular symlink and you must remove it. Does /usr/bin/convert point to itself?

Hi,

whats circular symlink.I have found
lrwxr-xr-x 1 root sys 7 May 6 14:33 convert -> convert

If i remove the link ,as its a live production server

please help on this..

Hi,

That should be safe to remove as it is a pointless link. If something is looking for convert you can either copy it from elsewhere or touch the file.

That's one, it points to itself.
Why was it created in May?

>If I remove the link, as it's a live production server

I assume the sysadmin made a mistake in creating a symlink. This is next to useless:
$ ln -s convert convert
$ cksum convert
cksum: can't open convert: Too many levels of symbolic links

And if there was a "good" reason for creating it, not being able to take an ignite backup is a more serious problem.

Hi ,

I removed the link using unlink command.Now the backup has been started.But i got below error.Please tell me whats this about

Do you have the latest ignite version?

[himacs]

Hi,

The server is running with old ignite version.
I have heard that memory fault error will kill the ignite process.But when i checked backup was alive.

Hi Gurus,

The issue has been resolved.Backup is fine now.
Thanx for your help.
But please explain me why circular symlink used.

>please explain me why circular symlink used.

I just assumed some sysadmin made a mistake in creating a symlink. I doubt they created it just so ignite wouldn't work. :-)

A useful circular symlink might be for directories:
ln -s .. FOO
But this can stop based on the next directory path entry.
