I know this is probably a somewhat 'dumb' question :)

I have an AWS (small) instance and I just noticed that there is a ~150gb volume attached at /mnt, is this normal?

It kinda freaked me out, I was thinking maybe someone was trying to capture whatever I mount in /mnt, there is the entry in my fstab too (and I found that others have this by googling)... the entry is as follows

/dev/xvdb   /mnt    auto    defaults,nobootwait,comment=cloudconfig 0   2

I don't have any volumes this large in my AWS volumes section though. I was just trying to understand this and be sure that someone is not trying to 'get in'... as there are many attempts daily.

Thanks
