File System Basics

Remember to check out wiki.software.List.fstab

    # What Systems are mounted
    df -hT
    # Take a look at the drives
    lsblk
    # or
    blkid
    # or
    fdisk -l
    # or
    gdisk
    # or
    parted -l
    # Manage Paritioning Tool
    cfdisk

Mount the installation disk

    mkdir /mnt/repo
    lsblk
    mount -o loop /dev/sr0 /mnt/repo

How to make bootable USB

    # Take a look at the drives lsblk
    # Make a bootable drive
    sudo dd bs=4M if=input.iso of=/dev/sd<?> conv=fdatasync

How to delete a file system

    # Clear all parition tables on drive
    wipefs -a -f /dev/???
    wipefs -a -t gpt -f /dev/???

How to make a partition

  • Devices can be found listed at /dev/
  • Two tools can be used for making paritions fdisk and gdisk

How to make a file system

    # fdisk is for managing MBR partitions 

    mkfs.vfat /dev/$WHATEVER

    fsck.vfat

    df -h

    dump2fs /dev/$WHATEVER

    blkid # Get UUID of block device

    tune2fs -L LABEL_NAME /dev/$WHATEVER

    mkfs.xfs -f /dev/$WHATEVER

    mkdir /mnt/mount-location
    mount /dev/$WHATEVER /mnt/mount-location
    umount /mnt/mount-location

    xfs_info /dev/$WHATEVER

    xfs_repair /dev/$WHATEVER

    gdisk /dev/$WHATEVER

    ## To delete a parition table
    wipefs /dev/$WHATEVER

    mkfs -t ext4 /dev/$WHATEVER tune2fs -L LABEL_NAME /dev/$WHATEVER dump2fs /dev/$WHATEVER #+end_src ** Create a xfs file system #+begin_src bash
    Create a xfs parition
    mkfs -t xfs /dev/$WHATEVER
    or
    mkfs.xfs /dev/$WHATEVER
    Repair and stuff
    xfs_info /dev/$WHATEVER xfs_repair /dev/$WHATEVER

VFAT is for windows compatibility

One can run out of i nodes and not be able to write

The xfs file system is really fast and supports parallelization

Add label to drives

  • \=xfs_admin -L {NAME}} /dev/WHATEVER=
  • \=xfs_admin -l= to check label
  • \=tune2fs -L {NAME}} /dev/WHATEVER= #ext4 file name

  • Create, Mount, unmount, and Use VFAT, EXT4 and XFS File Systems

    e2label /dev/vdc1 "Backups"

Temporary Mounting

    mkdir /mnt/mount-location 
    mount /dev/$WHATEVER /mnt/mount-location
    umount /mnt/mount-location
