Hello,

kctune -v vx_maxlink

Should give you the current value of vx_maxlink parameter.

Are you sure that you have reached that limit?

For one file, you can find out the number of hard links like this:

ls -l your_file

-rw------- 1 root root 2379 Nov 12 2008 your_file

The second column (1 in this sample) contain has this info.


From man vx_maxlink:

vx_maxlink â Configure the number of links to a file

....

DESCRIPTION

The vx_maxlink tunable is used to configure the number of links possible to a file on VxFS filesystem

As vx_maxlink is initialized when system is booted, the changes made to vx_maxlink will take effect only from the next system reboot.

As Horia asked, any reason you think you need more than that many hardlinks to the same file?

Hi,

You can use #kcusage to check the usage

>will let you know the error when I am creating any link.

If you go crazy, you get this error:
ln: too many links to make_hlink
-rwxrwxr-x 32767 326 Apr 20 15:42 make_hlink

EMLINK The maximum number of links to a file would be exceeded.

>when I am creating any link

Any link to any file? Meaning that you get an error even if you try to make a link to a file with a small number of links to it? Try to make a new file (touch test.txt) and then try to make a hard link to it (ln -f test.txt link1.txt)

This parameter (vx_maxlink) sets the number of possible links to a file. Not to all files (combined - sum of all links to all files from the filesystem).
