If you are getting the FSCK error fsck.ext3: Unable to resolve ‘UUID=a3e1dbca-60ee-4aa4-bf79-60cf6d96075d’ on system booting, then you can try following steps to resolve that :

1. Use following command to get the UUID of current partitions.

blkid

2. Open the /etc/fstab file and check the UUID in the fstab and the result of blkid are same.

unni[~]# grep -A 1 /dev/sda7 /etc/fstab
# /dev/sda7
UUID=a3e1dbca-60ee-4aa4-bf79-60cf6d96075d /media/olinux ext3 relatime 0 2

unni[~]# blkid | grep /dev/sda7
/dev/sda7: UUID=”9758e919-a56d-44cc-8c7e-a6ab9ff03151″ SEC_TYPE=”ext2″ TYPE=”ext3″ LABEL=”Olinux”

3. Edit the /etc/fstab and change the UUID to that got from the blkid 

That will solve the issue.
