In our last post, we talked about how to check for unreleased cursors in SQL Server. Today, let’s see how to mount a disk in AWS.
Steps to mount a disk in AWS
1. Create an EC2 instance.
2. Create an EBS volume and associate it with the EC2 instance via the console (Make sure the EBS and EC2 are in the same availability zone, i.e., within the same subnet).
3. SSH into the EC2 instance and create a mount directory.
4. Perform the mount operation as follows:
##Run the following commands in the root directory: mkdir /data [root@ip ~]# df -Th Filesystem Type Size Used Avail Use% Mounted on devtmpfs devtmpfs 468M 0 468M 0% /dev tmpfs tmpfs 477M 0 477M 0% /dev/shm tmpfs tmpfs 477M 408K 476M 1% /run tmpfs tmpfs 477M 0 477M 0% /sys/fs/cgroup /dev/xvda1 xfs 20G 1.8G 19G 9% / tmpfs tmpfs 96M 0 96M 0% /run/user/1000 [root@ip ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT xvda 202:0 0 20G 0 disk └─xvda1 202:1 0 20G 0 part / xvdb 202:16 0 100G 0 disk ## Check if the volume has a file system. If the file system is missing, the volume cannot be mounted. ## Use the file -s command to get information about a specific device, such as its file system type. If the output only shows "data" (as in the example output below), it indicates that the device does not have a file system. [root@ip ~]# file -s /dev/xvdb /dev/xvdb:data ##Use Case: Mounting an empty volume. mkfs -t xfs /dev/xvdb ##Mount the volume mount /dev/xvdf /data ##After restarting the instance, the mount point will not persist. Add the following entry to /etc/fstab to ensure the device is mounted at the specified mount point upon reboot. /dev/xvdb /data xfs defaults,noatime 0 2 ##Once configured, you can reboot the server to test the setup.
