md1 (swap) partition in RAID0

[f2cal6fg]

Hi all!

 

Has anyone ever tried configuring md1/swap partition with RAID0 instead of default RAID1?

 

I have terrible QD and latency using swap. My Synology NAS has small built-in memory so it often pages in and out. My theory is that 4 HDDs in RAID0 (instead of RAID1) for swap partition should give slightly better random read and writes.

 

Any experience out there please?

So I enabled swapfile on a different volume with higher priority instead.

Make sure swapfile priority is higher than of other swaps.

Configure swapfile setup on system boot.

 

$ sudo truncate -s 2G /volumeX/swapfile
$ sudo mkswap /volumeX/swapfile
$ sudo swapon -p 9 /volumeX/swapfile
$ swapon --show
