swapinfo

[navin]

hello All,
I have a very limited free disk space but having lot of space in my root filesystem, i have been suggested to go with the below command inorder to use the space in / for swap.But usually in other platforms we create the file and add that to swap. So i just would like to double check the below script is good or not
swapon -m 12288M -l 12288M /
please advice
thanks

The command looks correct but on a few tests I did, the -m and -l are mutually exclusive. The man page does not mention anything like that. Maybe because the host I tried this on uses vxfs as the fs type for /. You should add the -p option so that the lvol2 is used first and / is used second. You should also add an entry in /etc/fstab to activate this at boot time if it is required.
But before you do this, what is the objective here? Why do you need to add filesystem swap? Perhaps you are heading in the wrong direction.

Lookup "man 1m swapon" to understand the options being used.

Also, note that file system swap is a work-around, not a solution. Performance wise, disk swap is any day better than fs swap.

You can also use SAM to add filesystem swap.
