3. LVM (Logical Volume Manager) (Official site)
LVM provides a way to manage disk drives and storage by combining multiple physical disks into a single logical volume. It allows for dynamic disk management, making it easier to resize, move, and manage storage without downtime.
Installation
sudo apt install lvm2Usage
- Create a physical volume:
sudo pvcreate /dev/sdb - Create a volume group:
sudo vgcreate my_volume_group /dev/sdb - Create a logical volume:
sudo lvcreate -n my_logical_volume -L 10G my_volume_group
4. Filesystem Utilities (mkfs, fsck) (Official site)
Linux provides a variety of filesystem utilities to create and check filesystems. The mkfs command is used to create a filesystem, while fsck is used to check and repair filesystems.
Installation
No additional installation is required as these utilities come pre-installed with most Linux distributions.
Usage
- Create a filesystem:
sudo mkfs.ext4 /dev/sdb1 - Check a filesystem:
sudo fsck /dev/sdb1
5. rsync (Official site)
Rsync is a powerful tool for synchronizing files and directories between storage locations. It is particularly useful for backups and reducing bandwidth usage when transferring files over a network.
Installation
sudo apt install rsyncUsage
- Synchronize a directory:
rsync -av /source/directory/ /destination/directory/ - Backup a remote directory:
rsync -avz /local/directory user@remote:/path/to/destination
Troubleshooting Common Issues
- Ensure you have sufficient permissions (
sudo) to manage partitions. - Check for unmounted partitions before resizing them.
- If a filesystem check fails, use
fsckin rescue mode.
Summary Checklist
- Install your chosen tools using the package manager.
- Understand basic commands and options for each tool.
- Backup important data before making changes to your disk layout.
- Utilize rsync for efficient backups and transfers.
