See EBS Volume Types . One of the most common problem in Redhat Linux is “read only root filesystem” when there is issue with hardware or SAN sub-systems .To fix the “read only filesystem” issue ,you need to reboot the server.But while rebooting the server, you will definitely encounter many issues and that requires a manual intervention by logging in with the root. The main operation system has been shut down with the the quick start mode enabled. Click Skip to mount the volumes in the read-only mode. However, to make it usable as storage inside the instance, you need to mount it to a specific folder. If you need to mount the partition in read-write mode and are not able to or willing to boot into Windows and shut it down completely there is a third option.
Solution. Volumes have several advantages over bind mounts: The Third Option. Follow the steps given below carefully for the setup. AWS allows you to create new EBS volumes and you can attach it to instances for extra storage. A common example of this is a large number of SCSI errors on a device causing it to protect itself by going read-only. Malware will not be disinfected in this mode. EBS volumes mimic ordinary hard drives, except that their capacity can be manually increased on demand (but not decreased), and can be converted from one volume type to another without shutting down the system. However you will not be able to write to the partition or modify any files as it is in read only mode. If you need to mount the partition in read-write mode and are not able to or willing to boot into Windows and shut it down completely there is a third option. This option exists for support of the Linux autofs-based automounter.-r, --read-only: Mount the filesystem read-only. Tolerate sloppy mount options rather than failing. But I have to agree, this is a more exhaustive way to check. Use volumes Estimated reading time: 16 minutes Volumes are the preferred mechanism for persisting data generated by and used by Docker containers. This option ignores mount options not supported by a filesystem type. Choose one of the options: Click Continue to mount the volumes in the read-write mode. Creating a file will verify read+write/read-only without a doubt. A synonym is -o ro. While bind mounts are dependent on the directory structure of the host machine, volumes are completely managed by Docker.
Not all filesystems support this option.
Mount an EBS volume to EC2 Linux In this tutorial, we will teach you how to attach and mount an EBS volume to ec2 Linux instances. EBS volumes are available as both SSD and spinning platter magnetic volumes, again with tradeoffs in cost, performance, and appropriate applications. There are occasions mount can report that it is mounted read/write, but is actually read-only. However, it is not included here because it completely deletes hiberfil.sys and will cause you to lose all unsaved information in the hibernated Windows programs.
This may cause corruption of the file system.
