How to link a file from /var to / ?
 

Hi LQ,

I have a Mysql file(which may grow to 14G) residing in /var directory. Total size of the /var is just 10GB,so i want to link(hard/sym) it(if possible..I'm not sure) to some other file(may be a new file) on / dir. As i have 30G of / dir.


Thanks in Advance.

When you are trying to make sym-link using ln -s, does it show link (broken) (inode/symlink) for linked file?
Does it show size approx 10 bytes?
or
Are you implementing it using another method?

hard links are only usable in a partition that file is exist.
you can move your file to / and then make symbolic link to var.
symbolic links make in this way :

Ravi, Im not aware of your systems physical configuration, so this suggestion will be vagueish....

If this is long term or not a fun activity, Id suggest get yourself a separate filesystem for mysql and if you cannot migrate your mysql installation from /var to the new mysql filesystem, move your mysql data files to the new filesystem and link the files from there.

Placing non OS files on / is not a good idea...
