Formatting USB or Partition with "vfat" and "ext3" file system.

A. How to format USB or other partitions, so that we can access them in to Windows.


Steps :




Here I am using my 4GB USB drive for demo which is detected by “fdisk –l” command as “/dev/sdb” device file. Note that the device USB or the partition to be formatted should be unmounted. You can check it by “mount” command, if mounted use “umount <mount point OR device file name>”.

  1.                       
  2. Now with the help of below command we are going to format this USB with a “vFat” partition, because windows supports either FAT32 or NTFS .

                          
After the above command executed successfully, your USB or any partition will be ready to use with Windows compatibility.



B. How to format USB or other partitions with "ext3" filesysystem.

“ext3” is the main file system type in the Linux systems. So to format USB or a partition with “ext3”, follow below steps.

Steps:

  1. Here I am using my 4GB USB drive for demo which is detected by “fdisk –l” command as “/dev/sdb” device file. Note that the device USB or the partition to be formatted should be unmounted. You can check it by “mount” command, if mounted use “umount <mount point OR device file name>”.

                        
  2. Follow the below command with care as in your system the device file name “/dev/sdb” can be different. After execution it’ll ask for confirmation, so press “y” + Enter. Note that, before unmounting any partition or USB you have to come out of the mounted directory.

                         
Here your USB is ready to mount & use.

You can mount “ext3” partition or USB with command,

                                    

To unmount partition or USB device,
                             
                                    
                                             

Done :)

Recover or restore initramfs file in RHEL or CentOS 7

What if "initramfs" file is deleted or corrupted on your RHEL or CentOS 7 ? Lets know what is initramfs image ? The INITial RAM Disk (initrd) is an initial root file system that usually get mounted prior to when the real root file system gets available. The "initrd" image is also known as "initramfs (Initial RAM FileSystem)" from RHEL 6.x onwards. The initrd/initramfs gets bound to the kernel and loaded as part of the kernel boot procedure. The kernel then mounts this initrd/initramfs as part of the two-stage boot process to load the modules to make the real file systems available and mount's the real root file system. Initrd/Initramfs image provides the capability to load a RAM disk by the boot loader. This RAM disk can then be mounted as the root filesystem and programs can be run from it. Afterwards, a new root file system can be mounted from a different device. The previous root filesystem which was mounted from initrd/initramfs is then

Space reclamation / UNMAP on RHEL or CentOS 7

What is Space Reclamation? This feature supports Thin Provisioned environment, and it is the process of freeing space from the storage system that has already been freed from the host file system. A host file system contains metadata to keep track to know which blocks are available to store new data and which blocks contain actual data and must not be overwritten. This metadata is stored within the LUN. When a file is deleted in the host file system, the file system metadata is updated to mark that file's blocks as free space. Total file system free space is then recalculated to include the newly-freed blocks. To the storage system, these metadata updates appear no different than any other writes being performed by the host. Therefore, the storage system is unaware that any deletions have occurred. What is Unmapping? Unmapping is a process which de-allocates relationship between LBA and a physical block in a logical unit. Reclamation within RHEL and CentOS: RHEL / Ce
