NAS or RAID Storage Array: critically low free space. The operating system cannot allocate working space for updates, caches or snapshots.

The distinguishing clue

Startup and applications slow while free space approaches zero.

Checks before an assessment

Record the storage system's alerts and which bays contain which drives. Do not initialise disks, change their order or begin a rebuild before assessing the array and backup state.

Stop point: Changing drive order or initialising disks can destroy recoverable array metadata.

Workshop confirmation and repair

Device-level check: Record drive order and array state, inspect each disk and preserve configuration before replacing anything.

Targeted check: Measure real allocation, snapshots and large files before deleting data. If confirmed: Create verified free space and correct the process that consumed it.

Repair boundary: Replace only the confirmed failed member and follow the correct rebuild or recovery process for that array.

Related cause to rule out

When health warnings, read retries or increasing bad blocks appear, also consider NAS or RAID Storage Array: worn storage media before choosing a repair.

Checks after the work

After repair or replacement, check share access, redundancy state, alerts, restart and backup verification.
