Linux Administration

For teams that need dependable infrastructure without hiring a full-time sysadmin.

Where we help

Setup & migration — provisioning, web/mail/DNS services, and clean migrations with minimal downtime.
Hardening — sane defaults, firewalling, SSH and access policy, TLS, and automated backups you can actually restore.
Maintenance — updates, monitoring, and being on call when something breaks.

Ceph & distributed storage

When one server’s storage isn’t enough — or a single point of failure isn’t acceptable — Ceph gives you scale-out, self-healing storage on commodity hardware: object (S3-compatible), block, and file, from a single cluster.

Design & deployment — cluster architecture, CRUSH layout, replication vs erasure coding, and sizing for the workload.
Operations & tuning — monitoring, performance tuning, capacity planning, and safe upgrades.
Troubleshooting & recovery — degraded clusters, OSD failures, slow ops, and getting back to HEALTH_OK without losing data.
