LVM Consulting & Administration

Logical Volume Manager (LVM) is the backbone of flexible, scalable storage on Linux — but misconfiguration or poor design can lead to downtime, performance issues, or data loss. Zwiegnet delivers expert LVM administration and consulting to maximize reliability, efficiency, and recoverability.

Our LVM services include:

• Thin Provisioning & Overcommitment – Design and manage thin pools, thin volumes, overprovisioning safely, and monitor space usage to prevent out-of-space failures.
• LVM Snapshots & Backup Strategies – Create, manage, and automate thin snapshots; integrate with backup tools (rsync, Restic, Borg) for consistent point-in-time recovery.
• RAID Integration & Striping – Combine LVM with mdadm RAID (RAID-0/1/5/6/10), optimize striping for performance, and configure RAID + LVM hybrid layouts.
• Dynamic Resizing & Online Operations – Extend/shrink logical volumes, physical volumes, and volume groups online without downtime; pvmove for seamless disk replacement.
• Performance Tuning – Stripe alignment, I/O scheduler optimization, read-ahead tuning, cache settings, and benchmarking (fio, iostat) for high-IOPS workloads.
• Recovery & Troubleshooting – Recover from LVM metadata corruption, missing PVs, failed RAID legs, and split-brain scenarios using vgcfgrestore, pvscan, and lvmcache tools.
• Migration & Modernization – Migrate LVM volumes between servers, from LVM to ZFS/btrfs, or to cloud block storage; pvmove and lvconvert for seamless transitions.
• High Availability & Clustering – LVM with Pacemaker/Corosync for shared storage failover, clustered volume groups, and tag-based management.

Ideal for: enterprises running large databases, virtualization hosts, file servers, backup systems, and high-performance workloads needing flexible, resilient storage on Linux.
