Swap usage

[carles89]

Hi,

One of our servers seems that's using all SWAP, even with RAM available. Is it normal? Note that we've never changed vm.swapiness on this server, so it's in its default value.


Thank you all!

You must set the swappiness.

Hi Fireon,

Swapiness is set at its default value (60). Is there any recommended value?

On ZFS I use 10 (as indicated by wiki), but this server storage is based on LVM on a HW RAID10 Enterprise SSD.

Thanks!

We use on all us Server "10" or "0" depending on situation. "0" means swapping only when no more memory is available.
