Filesystem Corruption Is Not Disk Failure: Evidence-Based Triage and Capacity Recovery Using Block-Level Diagnostics and Remapping
Keywords:
filesystem integrity, fsck, ext4, bad blocks, block device health, badblocks, device-mapper, linear mapping, capacity recovery, operational triage, CAPEXAbstract
Operational storage teams sometimes treat filesystem-check results (for example, fsck reports) as proof ofphysical disk failure, leading to premature retirement of storage devices and avoidable replacement costs. This article clarifies the critical distinction between filesystem integrity failures
