Linux Storage: Master Data Management and Storage Systems

Linux storage management encompasses disk partitioning, logical volume management (LVM), RAID configurations, file systems (ext4, XFS, Btrfs), network storage (NFS, iSCSI), and distributed storage systems (Ceph, GlusterFS). Proper storage management ensures data availability, performance, and reliability.

• Data Growth: Storage needs grow exponentially
• Reliability: Data loss can be catastrophic for businesses
• Performance: Storage is often the biggest bottleneck
• Flexibility: LVM and modern file systems enable dynamic management

• Linux Administrators: Manage disk and storage infrastructure
• Storage Engineers: Design enterprise storage solutions
• Database Administrators: Optimize storage for databases
• Cloud Engineers: Manage cloud storage and volumes

• Disk partitioning (fdisk, parted)
• LVM (Logical Volume Management)
• RAID configurations
• File systems (ext4, XFS, Btrfs, ZFS)
• NFS and Samba file sharing
• iSCSI and SAN connectivity
• Backup strategies
• Storage monitoring and optimization

1. Partitioning: fdisk, parted, GPT vs MBR
2. File Systems: ext4, XFS creation and management
3. LVM: Physical, volume groups, logical volumes
4. RAID: Software RAID levels and configuration
5. Network Storage: NFS, iSCSI, Samba
6. Advanced: Ceph, GlusterFS, ZFS
