Know the moment a RAID array degrades. NexoraNAS watches array and pool state on every NAS and alerts you so a single disk failure does not become data loss.

Why RAID Needs Monitoring
RAID keeps a NAS running when a disk fails, which is exactly why a failure can go unnoticed. The array shows as working in degraded mode, users see no problem, and the only protection left is that no second disk fails before the first is replaced and rebuilt.
NexoraNAS watches RAID level and state for each array or storage pool and raises an alert the moment it leaves the healthy state, so the clock on your exposure starts when you are told, not weeks later.
RAID is redundancy, not backup. It does not protect against deletion, corruption or ransomware, and monitoring does not change that.
What NexoraNAS Shows for RAID
Array and pool state
Healthy, degraded, rebuilding or failed for every array.
Member disks
Which disks belong to the array and which one is the problem.
Rebuild progress
Rebuild status where the device reports it, so you know when protection returns.
Immediate alerts
Notification on any state change, not just on total failure.
Volume mapping
Which volumes and shares sit on which array.
History
When the array changed state and for how long.
Shorten the Window of Risk
The time between a disk failing and the array being healthy again is when you are one failure away from data loss. Fast notification, a clear view of which disk failed and rebuild status shorten that window.
- Alert on degraded, not only failed
- Failed disk identified by bay
- Rebuild status tracking
- Spare and hot-spare awareness where reported
- Same view for all NAS brands
From Alert to Healthy Array
Alert
You receive a degraded array alert.
Identify
Dashboard shows the failed disk and bay.
Check backup
Confirm a recent backup exists.
Replace
Swap the disk.
Rebuild
Track rebuild until healthy.
Array States
| State | Meaning | Action |
|---|---|---|
| Healthy | All members online | None |
| Degraded | A disk missing or failed | Replace now |
| Rebuilding | New disk being synced | Avoid heavy load |
| Failed | Too many disks lost | Restore from backup |

RAID Monitoring Software for NAS – FAQ
A degraded array is one that has lost a member disk but still works because of redundancy, for example RAID 1, 5, 6 or 10. Data stays available, but protection is reduced or gone until the failed disk is replaced and the array rebuilt. During that time another failure can cause data loss, so a degraded state should trigger action the same day.
NexoraNAS shows array state as reported by the NAS, which covers common levels such as RAID 0, 1, 5, 6 and 10 and vendor-specific pools, depending on the device. Some vendor technologies expose less detail than classic RAID. We confirm per model what the dashboard will show for your arrays during the demo.
You are alerted when the array enters a degraded or rebuilding state and again when it returns to healthy, so you see both the start and the end of the exposure. If the device reports rebuild progress, NexoraNAS shows it. If a second disk fails during rebuild, a critical alert is raised right away.
Monitoring cannot stop a disk from failing, but it can shorten the time you spend degraded and warn you about disks that are likely to fail next. Together with S.M.A.R.T. checks, temperature alerts and capacity trends it lowers the odds that one failure turns into several. It does not replace backups.
No. RAID protects against a disk failure, while a backup protects against deletion, corruption, ransomware, theft and disasters. Many data losses happen on healthy RAID arrays. Keep a separate, tested backup, ideally with one copy off-site, and use monitoring to make sure both the NAS and the backup jobs are healthy.
