Helpful Filesystem Tips

  • change reserved space on ext4 partitions to zero. Useful for drives specifically for data storage and no system recovery needed.

    # tune2fs -m 0 /dev/sdb1

  • print UUID of filesystems

    # blkid

  • remount a readonly filesystem to rewrite

    # mount -o remount,rw /

  • watch the status of dd (useful on systems without "status=progress", like Mac I think)

    # kill -USR1 $(pgrep ^dd)

  • lazy unmount an NFS mount that no longer exists on the network, if it’s hung

    # umount -l /media/bosch

  • fill entire disk with one partition, using optimized sector allocation

    # parted /dev/sdb mkpart primary 0% 100%

  • format disk partition

    # mkfs -t ext4 /dev/sdb1
