EC2 Filesystem / Files stored on the wrong partiton after launching new instance from AMI
- by Philip Isaacs
Today I set up a new EC2 Instance from and AMI I created from an older EC2 instance. When I launched the new instance I took the AMI that was on a small instance and launched with a medium instance. From what I can tell this is pretty standard stuff. But here's the stang part.
According to AWS these are the differences
Small Instance (Default) 1.7 GB of memory, 1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit), 160 GB of local instance storage, 32-bit or 64-bit platform
Medium Instance 3.75 GB of memory, 2 EC2 Compute Units (1 virtual core with 2 EC2 Compute Units each), 410 GB of local instance storage, 32-bit or 64-bit platform
Okay now here's where I'm having an issue. I when I log into the new bigger instance it still reports only having 1.7 GB of ram.
The other strange part is that all my old partitions are still their in the same configurations. I see a new larger partition /mnt which is essential empty.
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 7.9G 5.9G 1.6G 79% /
none 846M 120K 846M 1% /dev
none 879M 0 879M 0% /dev/shm
none 879M 76K 878M 1% /var/run
none 879M 0 879M 0% /var/lock
none 879M 0 879M 0% /lib/init/rw
/dev/sda2 335G 195M 318G 1% /mnt
/dev/sdf 16G 9.9G 5.1G 67% /var2
This EC2 is a web server and I was serving files off the /var2 directory but for some reason the instance is storing everything on /
Okay here's what I'd like to do. Move all my website files to /mnt and have the web server point to that.
Any suggestions? If it helps here is what my fstab looks like as well.
root@myserver:/var# mount -l
/dev/sda1 on / type ext3 (rw) [cloudimg-rootfs]
proc on /proc type proc (rw,noexec,nosuid,nodev)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
none on /dev type devtmpfs (rw,mode=0755)
none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
none on /dev/shm type tmpfs (rw,nosuid,nodev)
none on /var/run type tmpfs (rw,nosuid,mode=0755)
none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
/dev/sda2 on /mnt type ext3 (rw)
/dev/sdf on /var2 type ext4 (rw,noatime)
I hope this question makes sense. Basically i want my old files on this new partition.
Thanks in advance
