Good afternoon,
I am new to EC2 and have been trying to mount an EBS volume on an EC2 instance. Following the instructions at this StackOverflow question I did the following:
1. Format file system /dev/xvdf (Ubuntu's internal name for this particular device number):
sudo mkfs.ext4 /dev/xvdf
2. Mount file system (with update to /etc/fstab so it stays mounted on reboot):
sudo mkdir -m 000 /vol
echo "/dev/xvdf /vol auto noatime 0 0" | sudo tee -a /etc/fstab
sudo mount /vol
There now appears to be a folder (or volume) at /vol
but it has been (prepopulated?) with a folder entitled lost+found
, and does not have the 15GB that I assigned to the EBS volume (it has something much smaller).
Any help you could provide would be appreciated. Thanks!
UPDATE 1
After following the first suggestion (sudo mount /dev/xvdf /vol
), here is the output of df:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/xvda1 8256952 791440 7046084 11% /
udev 294216 8 294208 1% /dev
tmpfs 120876 164 120712 1% /run
none 5120 0 5120 0% /run/lock
none 302188 0 302188 0% /run/shm
/dev/xvdf 15481840 169456 14525952 2% /vol
This might indicate that I do in fact have the 15GB on /vol
. However I still do have that strange lost+found
folder in there. Anything I should be worried about?

Nothing is wrong with your /vol. It was mounted as shown by df
output.
lost+found
directory is used by filesystem to recover broken files (fsck stores recovered files there), so it's normal you can see it.
Small size problem might refer to kibibytes:
1 kibibyte = 2^10 = 1024 bytes
16G = 14.9Gib
