Agree completely with Kahlid on this. I run a number a machines
with no swap at all or with zram for swap.<br>
<br>
Also:<br>
<br>
swapon -s <br>
<br>
may be helpful here to see what current swap allocations are.<br>

<div>First, why do you want swap to be used at all? If it
is used, it means RAM is not enough, and you get really
bad performance on spindle disks, less so on SSDs.<br>
<br>
</div>
Second, if you are using swap a lot, then it would shorten
the lifespan of your SSD.<br>
<br>
Third, yes, please try parted as the message says. To do
this, just type:<br>
<br>
</div>
sudo parted<br>
<br>
</div>
Then enter:<br>
print devices<br>
</div>
You will see all the drives that parted knows about.<br>

<div>My Lenovo laptop came with a 1TB HDD, and a 16gig
sSata drive. It originally shipped with Windows 8 but I
eventually wiped the whole 1TB and installed Ubuntu
13.10 on it. Runs great.</div>
<div><br>
</div>
<div>One thing I noticed is that the 16gig mSata is not
being used. I would like to use it a my /swap
partition. As it happens, there is no swap partition on
the system.</div>

<div>As you can see, there is no swap partition. I
_thought_ I set up the mSata as the swap, during the
install, but apparently not.</div>
<div><br>
</div>
<div>Please note that this machine has UEFI, but
SecureBoot is turned off. Damn Windows 8....</div>
<div><br>
</div>
<div>Does anyone have any ideas on how to set up the mSata
as the swap partition?<br>
</div>
