# Increasing MFS Size

I don't know when it has changed, but since then you can't allocat
e more than 4G for a MFS partition in OpenBSD. However 4G could be
quite small if you use /home as a MFS like myself.

So how can you fix it?

It's unbelievably easy. Open up /etc/login.conf, then you can find

``````````````````````````````````````````````````````````````````
daemon:\
        :ignorenologin:\
        :datasize=4096M:\
        :maxproc=infinity:\
        :openfiles-max=1024:\
        :openfiles-cur=128:\
        :stacksize-cur=8M:\
        :tc=default:
``````````````````````````````````````````````````````````````````

Change the datasize into a bigger number, like 16384M.

Voila! Problem solved.
