Understanding /proc File system

Understanding /proc File system:

Files that contain configuration information for all the devices connected to your computer are scattered throughout the "/proc" file system. The /proc file system also contains files full of information about system resources.


1. /proc/bus/usb: This file contains all info about USB (Universal Serial Bus) devices currently plugged into your system. USB devices like mice, cameras, and serial storage devices currently connected to your computer.

2. /proc/scsi/scsi: This file contains all information about every SCSI devices currently attached to your system.

3. /proc/cpuinfo: This file contains a collection of all information about the system’s CPU.

4. /proc/crypto: The /proc/crypto file contains information about the current encryption algorithms and digital signature tools installed on your system.

5. /proc/meminfo: This file contains a wealth of information about your system’s memory resources.

6. /proc/filesystems: This file contains information about the all file system types that can be mounted on your system. Check out "/proc/filesystems" to find out what kind of drives you can mount on your system. If ntfs isn’t in the list, you can’t mount Windows drives on your Linux box.

7. /proc/bus/pci/devices: This file contains all info about PCI cards connected to your system.

8. /proc/bus/input/devices : This file contains all info about input devices like, Keyboard, mouse, webcam etc.

9. /proc/mdstat : This file contains all info about RAID device.

10. /proc/modules : This file contains all info about all the loaded modules on Linux box.

11. /proc/partitions : This file contains all info about all the available partitions.

12. /proc/swaps : This will display info about currently assigned swap space.

13. /proc/version : Will show same output as of "uname -a" command i.e. info about kernel and architecture.

14. /proc/mounts : Will show you all the mounted partitions with their respected mount points, same as by "mount" command.

15. /proc/ide/drivers : This will display info about currently added IDE devices.

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
